OUTSTAITDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR JULY, 1927

Scouting for the European corn borer has been in progress for onlythree days, as the seasonal development is late. Scouting up to this datehas been limited to confirmation of the presence of the borers in the coun-ties on the border of the quarantine area and the crews are reporting themin these counties in numbers at least as great as those found in 1926.

Throughout the eastern part of the United States one of the most con-spicuous features of the month was an unusual abundance of aphids on a greatvariety of crops and ornamental plants. Shade trees inmany places were al-most black with sooty mold.

The alfalfa weevil has advanced- from about 40 miles west of the nebraska-Wyoming line to about 8 miles west of that line.

The Hessian fly seems to be about normally prevalent throui1out thcwheat belt with the exception of the Kansas area, where it is estimated that20,000,000 bushels of wheat were destroyed by this insect.

Allowing for the alarm caused by the European corn borer, the commonstalk borer appears to be unusually prevalen:t throughout the Mddle Atlantic,East-Central, and West-Central States.

The black cutworm continued throughout the month to be a serious pestin the recently flooded areas of :.: ssissippi and several points.in Indianaand Nebraska.

Scouting for the Japanese beetle outside the area now under quarantinehas been in -operation about one week, It is too early to tell whether therewill be extensive spread of the general infestation but a strong movement tothe south is indicated.

In the Ohio River Valley the codling moth was somewhat later thanusual in emerging. This, coupled with the destruction of the fruit by frost,has very materially reduced the population of this insect.

An interesting note has been received from Maine reporting destructionof fruit buds by elaterit adults. This type of attack has been recorded forseveral years from the Pacific Northwest.

In Georgia the oriental fruit moth has spread from the f6w orchardswhere it was recorded in 1926 to the entire Fort Valley district.

The plum curculio has been unusually prevalent and destructive over theentire Atlantic seaboard.

Owing to unusual weather conditions the cherry maggot was so greatlydelayed as ,to render.it of no importance to the cherry crop in Michigan.

been.Mealybug infestations have/materially heavier than during last year in

the southern California citrus belt. During the month of May of this year,the Los Angeles County insectary liberated 1,612,.000 Cryptolaemus beetles,and during April another 5q0,00 were liberated to control this pest.

One of. the interesting features of the season has.been the finding ofthe Mexican fruit rorn in Texas early -in June. specimens were collected atMission, Hidalgo County and two points in Cameron County.

The Mexican bean beetle has very materially increased its area of in-festation. It has advanced eastward to T shingt.on and Frederick Counties inmaryland; in Virginia, to Norfolk and the Government Experimental Farm at

cilington near Washington, D. C.; in North Carolina, it has spread northeast--,ard to Wake and Robeson Counties; northward in Indiana to Indianapolis andRichmond and westward to Olen and Dubois Counties; in Pennsylvania, to ErieCounty; and in Michigan, to Uonroe County.

The seed corn maggot has been quite prevalent in parts of New York,

:ichigan, and Iowa.

Though unusually late in appearing in .the pepper fields of California

the pepper weevil is nowr well spread over the pepper-gro-.ing section and the

present indications arc that the loss :ill be heavy this year.

The boll weevil survived the winter in better condition than last year

in north Carolina, South Carolina, and Mississippi, while the records indicate

that survival was lower than last year in parts of Georgia, Alabama, and

Louisiana. Later reports indicate that this insect is generally more destruc-

tive than last year in North Carolina, central Georgia, Alabama, and :iss-

issippi. Little boll-weevil damage is reported from South Carolina, Louisiana,

and Texas.

The cotton flea hopper situation is decidedly better than last year,

practically no damage being reported from any part of the cotton belt.

The cotton leaf worm has stripped the cotton as far northward as San

Lrcns and eastward to Houston in Texas. In general this insect has not been

reported over the eastern part of the cotton belt as yet. A single specimen

of the leaf worm has been reported from Tcnnessee.

The tussock moth is generally more prevalent than usual over the Mid-

c10 Atlantic and East Central States extending westward to eastern Iowa and

NTbrackai.

OUTSTANDING ENTOMIOLOGICAL FEATURES IN CANADA, FOR JULY, 1927

Grasshoppers of several species are very heavily infesting open grassranges in south-central British Columbia from Ashcroft to Quesnel. Cattlecountry comprising some 2,000 square miles is badly infested and there is dan-ger of the range grasses being seriously reduced.

The clover root borer is gradually exterminating red and alsike cloversthroughout the north end of the OkanaganValley, and adjoining areas, inBritish Columbia.

A light infestation of the potato stem borer is reported thrcughoutthe southeastern counties of New Brunssaick, affecting a variety of field andgarden plants.

Reports of severe aireworm injury have been received from points insouthern " uebec, southern Manitoba, western Saskatchean, and Vancouver Island.

Observations at points in southern duebec and along the St. La'wrenceRiver show the onion-maggot infestation to be, in general, more severe than lastJ-oat,from& 40 to SO per cent of plants being infested.

The spruce budviorm is heavily infesting balsam, fir, and spruce over anarea of several hundred square miles north of Thor Lake, Ont. This outbreakhas been in progress since 1922, with the result that the fir is largely dyingor dead and. the spruce growth seriously retarded.

Eighty-eight per cent of cocoons of the larch sawfly examined in theSpruce Woods Reserve, anitoba, were found to be parasitised tith the intro-duced parasite, Hesolieus tenthredinus aorl. Adults of this parasite are be-ing liberated at points in Eastern Canada.

On the mainland east of Moose Island, in the vicinity of Lake innipeg,anitoba, the spruce bud';orm has entirely killed out mature balsam and has

weakened nhite spruce. A large percentage of the latter is being killed bythe bark beetle Ig perturbatus Eich.

The vrhite pine weevil is infesting the terminal shoots of young jackpine trees on the Sandilands For est Reserve, Manitoba.

There is a general and heavy infestation of the box elder plant louseon Mianitoba maples in Saskatchewan.

The satin moth was responsible for complete defoliation of infestedpoplar trees in the Victoria district. B. C., this summer.

:ith the completion of bark-beetle control work in the Aspen Grove dis-trict, the last of the berk-beetle outbreaks in yellow pine in British Columbiahas been brought under control, with a consequent saving of millions of dollarsworth of valuable timber.

In the Niagara peninsula, Ontario, the pear psylla heavily infestedunsprayed orchards and orchards that --ere sprayed too late.

The saskatoon sawfly, r2locamna halcyon N ort. , is abundant and wide-spread in southern Ianitoba, :here it destroyed 75 per cent of saskatoon berries.

Aphids of many species have been reported unusually abundant in -esternNova Scotia, the Niagara peninsula, Ontario, and central Saskatche-an. Seri-ous infestations of the green apple aphid on young apple trees are reported inthe Okanagan Valley, British Columbia.

Rose leafhoppers ere very abundant on roses in June and apples inJuly, in the Vernon district, British Columbia.

Severe out breaks of the apple leaf sever, Albononvna vicarialis Zell.have occurred in apple orchards of the Annapolis valley, ?ova Scctia, ;:herethe insect is more numerous than over previously recorced.

GRASSHOPPERS (Acrididae)

T. H. Parks (July 25): We anticipate no damage by grasshoppers

this year.

H. C. Severin (July 18): There are no grasshoppers to speak

of this year

M. H. Swenk (June 25 - July 25): A few reports only of injuryby grasshoppers are being received. There has been a moderate

hatch of these insects in the North Platte Valley, with some

threat of serious injury, and during the third week in July a

few reports of an abundance of grasshoppers in alfalfa fields

were received from scattered localities along the eastern

edge of the State.

WHITE GRUBS (Phvllophaa. sp.)

C. J. Drake (July 12): White-grub injury, brood "A,11 is begin-ning to show up in the entire eastern half of the State with

a few localities in the western half.

M. H. Swenk (June 25 - July 25): Since the middle of dune,scattering complaints of damage by white grubs to strawberrybeds and rose and flower gardens have been received.

Ohio

Illinois

Alabama

Minnesota

T. H. Parks (July 25): Aphids have had their inning this year.Almost every crop suffered more than usual. Spiraea led inthe shrub line. Potatoes and tomatoes were damaged in local-ities by 1linoia solanifolii. Ceen apple aphid appeared inmany orchards and damaged young trees. A field of sugar beetsin Lucas County was found to be almost destroyed by aphids Jb-ly 22. We have had the most severe visitation in years. Apb-ids on maple trees are now about gone, being controlled by par-asites and predators.

C. C. Compton (July 9): Many species of plant lice are unusu-ally abundant at this time. Cabbage is suffering most.

J. M. Robinson (June 30): Plant lice are showing up in spotsin central and southern Alabama. However, the paraites andpredacious forms are apparently keeping them considerably re-duc ed

A WIREWORM (Melanotus spp.) -

A. A. Mail (July 5): On a recent rrip throughout the south-western sections of the State, I found two wireworms whichappeared to be doing the heaviest damage and these I am go-ing to concentrate on as the major wireworm pest in Minne-

sota. The most abundant is the dark brown, very cylindricallarva which I think is Melanotus. In an infested field Iobtained a few 'beetles which I take to be the adults of the

. larvae. (Specimens determined by J. A. Hyslop as Melnotussp.)

CER-EA.L AND FORAGE - CROP INSECTS

MIS CELLANEOUS FEVERS

GREEN BUG (Toxoptera eraminum Rond.)

A. G. Ruggles (July 15): Toxotera graminum was found thinlydistributed over a wide area in southern Minnesota late inJune, the first ones found being isolated migrants. In a fewplaces,'on very late .,grain, there has been considerable increaseend slight injury seems likely. In most fields the grain iswell' headed and little increase of Toxoptera has occurred.

PEA APHID (Illinoia pisi Kalt.)

isconin J. E. Dudley (June.25): The general distribution and establish-.ment of aphids in pea fields, also alfalfa and clover, wouldseem tojustify the prediction that they will be more than usu-ally abundant in July, especially if the weather turns hot. Itis possible, however, that the aphid's enemies, particularlysyrphids, may be able to keep the infestation below normal.

ARMYWOPRM (Ci'rphis unipuncta Baw.)

Missouri

Nlebraska

L. Baseman (June 28): During the month two complaints were re-ceived with samples of specimens of the regular armyworm thoughno epidemic has developed

M. H. Swenk (June 25 - July 25): Reports of commercial damage bythe armyworm were not-so numerous as the cool weather seemed toindicate they would be, but the larvae were quite commonly andgenerally distributed in grass hnd grain fields over the south-estcrn part of the State.

WHEAT

'TiSSIAN FLY (Phytophaga destructcr Say). . :ende.-hall (July 6)y Clark County has about 13 per cent of

Hessian fly infestation' according to the recent wheat-field survey.(July 8): Champain .has about 8 per cent Hessian fly infestation

according to the recent "heat field survey. A reduction over last

year. So much for better cooperation in the proper time of seeding.(July 14): Logan Couty has 1 54 per cent Hessian fly infestation.

Py inspection they are found now in the "flaxseed" state or restingstage. Wheat was sown rather late but there wias a lot of volunteer

cheat ihich may be the cause.

T. H. Parks (July 25): The annual wheat survey has been com-pleted in Ohio. Thirty-four counties were inspected and thepercentage of Hessian fly infestation determined in each. Thesituation is satisfactory in the southern one-third of theState or south of a line drawn through Zanesville, Columbus,and Springfield. It increases in the north central belt, andthe northern half of the State has had a rapid increase in in-festation. Four counties in northwestern and one county innortheastern Ohio now have between 40 and 50 per cent infesta-tion of the straws. The average infestation fob the State is20.5 per cent compared with 9 per cent in 1926. The presentcrop did not suffer much owing to good growing weather and themost of the infested straws remained upright. The rapid in-crease in the infestation was due, to the presence of volunteerwheat which received the eggs of the fall brood last year andwhich was kept growing in the old stubble fields by abundantfall rains. We shall make an effort to hold off seeding thisfall and with normal fall weather, expect to win out.

R. H. Pettit (July 18): The Hessian fly appears to be comingback with us here and there. We have no facilities for mak-ing a survey over the State, but we find it in moderate numberswherever we look.

M. H. Swenk (June 25 - July 25): The unusually large 1926-87winter wheat crop of Nebraska came through harvest without anycommercial damage whatever by the hessian fly.

J. W. McColloch (July 21): There has been no material changein the Hessian-fly situation since my last report. I might saythat preliminary estimates indicate that this insect reducedthe wheat crop about 20,000,000 bushels.

WEET STEM MAGGOT (Meromyza americana Fitch)

M. H. Swenk (June 25 - July 25): During the last few days inJune and the first two weeks of July, the wheat stem maggotwas responsible for some serious damage to wheat and rye inthe northeastern portion of the State, from Greeley Countynortheast to Cedar County and northwest to Boyd County. Theinjury was mostly confined to scattering heads through thefields, but one Cedar County farmer reported that the pest haddestroyed about one-fourth of his crop of fall rye.

W~E STRAW W6IN Harmolita andis Riley)

Missouri L. BAseman (June 28): Farmers have been reporting small injuryfrom the work of the straw worm. It is no more abundant thanin most seasons but has attracted some attention.

ARMYWORM (Cirphis unipuncta Ha .)

J. W. McColloch (July 20): Last month I reported the heat headarmyarorm as injurious in. several localities. Field investigationssince then have sho 'm that most of the damage was due to the truearmy;-orm which took on the' habits of the 'vheat-head army'.7orm.In all cases a fe7 "heat-head arnyworms .'ere present.

guch damage has been done to corn drop farther east and south.

H. C. Severin (July 18): No chinch bugs to speak of this year.

M. H. Swenk (June 25 - July 25); Although the mortality of thechinch bug was apparently not excessive during the past winter,and the pest started the season with a menacing abundance inmany parts of southeastern Nebraska, the protracted perio' osubnormally cool weather that occurred during May and Juneslowed up the development of the first brood, while in mostlocalities timely cold rains proved fatal to a large percent-age of the young of this brood. The net resultshas been farless serious injury by this insect than was threatened at theclose of the winter. In only one area in the State did the in-festation develop to the point of an outbreak. This area in-cluded the whole of Lancaster County, about the northwesternone-fourth of Gage County, the southern edge of Gage County,and the southern edge and northwestern corner of Cass County.In this comparatively limited area the bugs started moving onJuly 2 and the movement continued for the next 10 days. Oil-line barriers were constructed in many fields over this areaduring the period mentioned, as the bugs moved from the wheatinto the near-by cornfields. Outside of this area the chinchbug apparently did no serious or commercial ,damage to corn du-ring the migration period.

J. W. Ma Colloch (July 20): Rains have checked the chinch. bugand the injury this year is materially less than last year.Scattered reports indicate local damage in several parts of theState. The second brood is just beginning to appear.

EUROPEAN CORN BORER (Pyrausta nubilalis Hfibn.)

L. H. Worthley (June 23): Scouting for the European cor3 borerhas been in progress only three days as the seasonal develop-ment is late. Eggs are now present in the fields in consider-.able numbers and some larme are as far along as the fourthinstar. The scouting up to this date has been limited to con-firmation. of the presence of the borers in the counties on theborder of the quarantine area and the crews are reporting themin these border counties in numbers at least as great as thosefound in 1926.

SCO.THERN dORN STALK BORER (Diatraea zeacol ella Dyar)

U. R. Walton (July 29):, On July: 25th, Pr. James chutrey of theBureau of Plant Industry submitted specimens of corn stalks heaviinfested by. this species collected on fair grounds at Upper Harl-boro on.popcorn. He stated that there had occurred total destruction of from 400 to 50Q plants on experimental plots. On July25th, ,ii. James U. Dennis of Trappe, Talbot County, submitted spemens.of field corn stating that serious injury to it had been donby the insect, Both larva and pupa stages of the insect :.ere present.

C, H. Brannon (July 20): Generally destructive to late-planted-corn.

J. 0. Pepper (July 11):. Cornstalks infested by this insect havebeen sent in-from"Florence. County. In five stalks there ",ere anaverage of three larvae per stalk.

STALK.BOR R (Papaipema nebris nitela Guen.)

A. I. Bourne-(July"25): From our:indications to date, the stalkborer for some reason ;or another is anot so abundant as is usuallythe case. - ".

E. P. Felt (July 25): This insect has been unusually abundantand destructive in -idely separated sections of the State, Sorkin,in young corn and various thick-stemmed plants. Possibly a por-tion of the reports are due to the present keen interest in theEuropean corn borer andiits .ork. .' .

F. :D. Sanders (June-July): Corn has been injured seriously overthe State by the common stalk borer. Farmers are generally alarmover its presence, believing it to be; the European corn borer. Tcold rainy spring no dotibt has made parasitism ineffective in holing the stalk borer in check, as normally it is of slight concerni. this State. It also attacks dahlia and hollyhock.

.. F. Gro7ell (July 5): On June 28 the Triter noticed the com-mon stalk borer in about, the second and third instars feedingi. corn that ";as about a foot high at forth East. A report came

- 201 -

to this office on J1y 1 that this insect is doing quite a bitof damage to flower beds in Erie.

Ohio E. W. Mendenhall (July 8): The stalk borer is very badiin Cham-paign County in corn plants and some think they have the Euro-pean corn borer; but when investigation is made we find it isthe common stalk borer.

T. H. Parks (July 25): Damage from the stalk borer has been moreabundant this season than usual. Specimens have been receivedalmost every day with the fear expressed that they may be theEuropean corn borer. Larvae are about full-grown at this writ-ing.

Indiana H. F. Dietz (June 28): The common stalk borer is being reportedwithin the last few days, June 22 to June 24. Most of our rec-ords have come from Marion County where in a number of casessmall garden lots have been seriously injured by unusual num-bers of these worms. At Danville this insect was found tunnel-ling wheat, and in Madison County over 50 per cent of a half-acre plot of sweet corn was destroyed.

In city flower grdens this borer has also been reported onsuch flowering plants as cosmos, dahlias, and zinnias anf' suchtruck crops as potatoes and tomatoes.

J. J. Davis (July 19): One of the outstanding pests of the monthwas the common stalk borer. Reports were first received June22 and have continued up to the date of this record, being mostnumerous the last few days in June and first week or ten daysin July. Greatest damage reported to corn, but also 2eesteetand popcorn. Next chop in importance was tomato. Other cropsattacked included potato, wheat, oats, mint, hollyhock, dahlia,and rhubarb, most of the reports coming from the northern two-thirds of the State. The general prevalence of this borerthroughout the State and the small size of the corn ereresultedin conspicuous losses to corn growers and others.

H. F. Dietz (July 21): Reports of the stalk borer, continue tobe received from various parts of the State. The hosts, ofcourse, are quite variable and whenever the insect is found incorn the writers immediately think they have the European cornborer. Reports of this insect in dahlias, tomatoes, asters,and zinnias are common.

Michigan R. H. Pettit (July 18): This is the worst year so far that wehave ever had with the common stalk borer. It is sent in some-times a dozen times a day with the request for information con-cerning it.

C. J. Drake (July 12): The common stalk borer is unusually abutdant in Iowa this year.. Over 100 different kinds of plantshave been found infested by the stalk borer at Ames. Specimenshave been received from almost every county in the State, andin some counties a considerable quantity of corn has been badlyinjured or even entirely destroyed by the insect.

L. Haseman (,Tune 28): Throughout the month the outstanding in-sect so far as inquiriesare concerned has been our common na-tive stalk borer. Farmers have suspected that it might be theEuropean corn borer. It has been unusually abundant this month

M. H. Swenk (June 25 - July 25): Complaints of injury by thestalk borer, that began to be received during the second weekin June from southeastern iebraska, as mentioned in my last re-port, increased to the status of an.outbreak during the lastweek in June and the first three weeks in July. Complaints ofinjury were received from practically every county in Nebraskalying east of the 98th meridian, and in the Platte River Val-ley the area of injury extended west to the 100th meridian.Over one-half of the complaints ref erred to injury to corn,which in :ome instances assumed quite a serious aspect; other-wise, the-complaints referred mainly to injury to potatoes, to-matoes, and thick-stemmed flowers, like hollyhock, etc.

J. W. McColloch (July 20): The stalk borer has been a predom-inatine insect in our ccrrbspondence this month, owing to thefact W~ratt every one is looking for the European corn corer..any farmers are reporting heavy losses from this pest. In afew cases the damage ,has been severe enough to cause abanaon-ment of the crop.,

C. J. Drake (July .29): A telegram July 29 reads "Big armywormoutbreak in Hardin and Franklin Counties."

YELLOW-STRIPED ARMYWORMI (Prodenia ornithoplli Guen.)

C. J. Drake (July 12): The cutworm Prodenia ornithopelli Guen.has been found in considerable numbers in Story, Woodbury, andWebster Counties during the first part of July.

R. W. Earned (July 25): The yellow-striped armyworm ranks sec-ond in importance among the cutworms in the overflowed areaa.Between May 16 and Jaly 21, reports with specimens were receiv-ed from Adams, Bolivar, Tallahatchie, Warren, 'ashington, andYazoo Counties.

CUTWORMS (Noctuidae)

C. J. Drake (July 12): Cutworms (various species) have been un-usually abundant in the'State this spring. A number of fieldsof corn were badly injured or even entirely destroyed.

J. J. Davis (July 19): Cutworms have been unusually abundantthe past month. Iost of them were apparently the greasy cut-worm. The first of these late cutworm reports came from Ko-komo June 27 where 20 acres of corn were said to have been de-stroyed. Late reports of damage to corn came from Peru, July2; Winamac, July 3; Muncie, July 4; Newburgh, July 6; Martins-ville, July 7; Rossville, July 9; and Terre Haute, July 14.

M. H. Swenk (June 25 - July 25): During the second and thirdweeks in July several reports were received of cornfields be-ing injured by the greasy cutworm, boring into the bottom ofthe stalks of young corn and killing the plants. This injuryassumed its most serious development in York County. One 40-acre field near Gresham had about one-third of the stand onseveral acres taken in this way, while another field of 35or 40 acres near Luhton suffered a loss of about 10 per centof the stand becaugy of this injury.

R. W. Warned (July 25): Arotis ypsilon Rott. continues to bethe most important cutworm in the counties that were recentlyflooded. Between May 25 and July 19, reports of injury by thisspecies accompanied by specimens were received from Bolivar,Yazoo, Quitman, Washington, Warren, Grenada, Tallahatchie,.dans, and Sunflower Counties.

BESSER CORN STALK BORER (Elasmopalpus lipposellus Zell.)

T. E. Holloway & "+. E. Haled (June 29): One field of corn nearGulfport was reported by various inspectors as having a pecu-liar injury. No specimens could be found by anyone, but it ap-pears that the damage was done by the lesser corn-stalk borer.The stalks were in many cases almost girdled at the surface ofthe pound, so that a strong wind caused them to fall over.

R. W. Warned (July 25): Although a month ago we were receivingcomplaints every day in regard to the lesser corn stalk borer,during the past three weeks only three lots of specimens havebeen received. These came from Newton County on July 15 withthe report that they were seriously injuring corn, and fromLee County on July 23 where they were attacking corn, and fromJefferson County on July 21 where they were attacking peas.

' LINED CORN BORER (Hadena fractilinea Grote)

E. P. Felt (June 27): We have just learned of a heavy infesta-tion in a cornfield in Broome county. (July 25): The lined cornborer has been injurious to corn on recently planted sod in Al-bany, Columbia, Rennslaer, Broome, and Oneida Counties, and insome instances caused considerable damage.

F. E. Brooks (June 27): Beetles arc unusually abundant and areat present ovipositing in apple and other host trees. The abund-ance of the beetles appocrs to be due to the scarcity of wood-pcckors in orcha rds during the past winter. A heavy crop ofbeechnuts last fall supplied intc: food for these birds and theyremained in the roods to an unusual degree. The dony woodpecker,-hich is normally destructive to these borers, scarcely left thewoods during the winter to obtain food in orchards or at artifi-cial feeding stations. In rather extensive collecting of ;roaring m-torial of these borers in early spring not an exampleof destruction by Goodpeckers was observed. Often 25 per cent ormore of the full-grown larvae are removed from their pupal quarterduring the -:intcr by woodpeckrs...

Snapp & Swingle (July 21): In 1925 the oriental peach moth in-festation in the Fort Valley section of the Georgia peach belt wasconfined to parts of six commercial orchards. In 1926 the insectcould be found in parts of only three of these orchards. A survey during the past veek revealed the fact that the insect hasspread this year to commercial peach orchards over practically theentire Fort Valley district. It w"as found throughout orchards toa point 12 miles north, 15 miles south, 6 miles east, and 2 milesnest from the city of Fort Valley.

Frequent rains during the fall of 1926 and the early summerof 1927 caused rapid twig growth, which furnished an abundantsupply of food for the development of the insect.

The infestation is very light throughout the area describedabove.

PLUMoe CtRCULIO (Conotrachelus nenuphar "rhst.)

A. I. Bourne (July 25): Pcobably the most serious pest of fruit -to date, at least the one that is causing the most anxiety togro-rers, is the plum curculio. It appears to be present in eves,greater abundance than last year, and even in v.ell sprayed or-chards has done a large amount of injury.

PI D. Sanders (July): The plum curculio has been unusually abund-ant this year in commercial apple and peach orchards. The failureto control it is generally attributed to the abundance of thespecies and the excessive rain during the spraying season whichtended to wash off the arsenical.

0. I. Snapp (July 20): The peach season is over in Georgia afterthe shipment of around 12,000 cars. The curculio infestation washeavier this year than at any time since 1923. There were twogenerations, the second generation attacking the Albertas. Theinsect gave the most trouble in poorly-cared-for orchards, and inthose that received an irregular schedule of sprays

L. Haseman (Juie 2v): adults of the second brood began emergingJune 25 to 20.

F. C. Bishopp (July 26): Although the first generation of theplum curculio did not appear to be especially abundant,the secondgeneration has caused heavy damage to midsummer peaches. As highas 60 per cent of the ripening fruit has been destroyed in someinstances, and many peaches were found to be infested with 3 ori4 larvae. The larvae have been emerging from peaches during the

past two weeks.

R. H/ Pettit (July 1$): An usual situation arose this year inthe case of the white-banded cherry fruit fly. Our field cages,maintained for the purpose of determining; the dates of emergenceof the adult flies in the southern part of the cherry belt, actu-ally produced adults this year after a portion of the cherries habeen picked and canned. It would seem, therefore, that the coldseason, at least on this occasion, delayed the insects more ef-fectively than it did the fruit. At any rate, no sprays -sere re-quired in the southwestern part of the State in order to hold thewhite-banded cherry fruit fly in check.

PEPPER WEEVIL (Anthonomug eagenii Cano)

J. C. Elmore (July 1): The first field infestation of the pepperweevil this year has been found near Santa Ana. Overwinteringadults were found early in April on overwintering plants, butnone have been found since in Orange County until July 1. Theinfestation referred to above is very light at this time. (July7): A 4-acre field of pimento peppers adjacent to a field ofoverintering plants where the weevils were numerous in April ofthis year was found to be infested. Thirty larvae were takenin butts. io adults were taken. About ten days of warm weatherhave had some effect on the development of the weevil no doubt.Other infestations are expected in other localities. (July 1L):The pepper weevil has been found to be well distributed over the

pepper growing section of Orange County in the last few days,and indications are that the losses will be heavy in a large num-ber of fields this year. The adults of the first spring genera-tion have just begun to emerge.

BEET EBUORM (Laphygma exim~ua Hubn.)

California J. C. Elmore (June 30): Generally distributed in pepper fieldsin the county, but numerous in certain areas. The larvae haveattacked every plant in parts of some fields, eating out the more

tender leaves and in ome cases completely defoliating the plants.1i:re d.amage is notice. near-pig.eed patches. The pupae of somedipterous parasite are cormnonly found near dead larvae of the Iarmyworm. Laphygma exigua has been found on peppers for threeyears, out not in such destructive numbers before,

. .. Es Campbell (July 1): Larvae are feeding mostly on weeds,particularly imaranthus, but to a considerable extent on youngpeppers. In several fields damage is considerable, and gTOwthwill be checked, but there is not entire defoliation. 7orms aremigrating from weeds to peppers in several places.

C. 0. Eddy' (July 19): Boll weevil infestations small and scat-tered in the Piedmont section.

0. I. Snapp(July 1): Weevils are fairly abundant in Houston an. in adjoining and near-by counties. There has already been some

dusting with calcium arsenate in the Fort Valley section forweevil control. Some rain ;was reported on 17 days during Juno,and with a good source of weevil infestation cotton growers are

. anticipating considerable .trouble from the insect this year.(July 20): The boll weevil is more abundant than usual in MiddleGeorgia. Considerable damage is being done in some fields. Thealmost daily rains since the sixth of June have materially aidedin the development of this insect in this region.

S. P. Dent (June 27): Reports indicate a rather widespreadlight infestation of weevils near Somerville.

J. Li. Robinson (June 30): The boll weevil is very active at Aubuirn.- The first-generation adults are out feeding on and puncturing the

squares. (July 5): A summary of reports from county agents andvocational agricultural teachers shows that there is a general andunusually heavy weevil infestation in the central and southernparts of the State. In southern Alabama cotton is well advancedfor this season of the year, mature bolls being common. The firstgeneration-of weevils are emerging and some are now depositingeggs. Weather conditions and size of cotton are such as to assurealmost 100 per cent emergence of this generation of weevils. OnJuly 27 and 28 the average infestation was 11.9 per cent on dustedplates at Auburn compared to 20.4 per cent on the undusted plats.

Miss.

Infestation is norvery heavy in some sections, amounting to 50 per cent and in somefields in the wcooded sections 100 per cent. It has been very un-usual -eather for Texas. (July 13): Boll-"aeevil infestations rangefrom 0 in young cotton to 95 per cent on large plantations in theBrazos Bottom. An aeroplane company has three ships ;corking in thisarea and plans to dust 11,000 acres. Boll Norms are also just be-ginning to become abundant in many sections of central Texas. Fif-teen counties in eastern Texas report boll--eevil injury.

Bauthofer, stationed at Halsey, Nebr., arrived in Ashe-"vilde,N.C.:to study the tip-moth situation about there, with a viewto obtaining new parasites to introduce in the plantations atHalsey. Later, accompanied by :r. St. George, he left Ashevillefor Bogalusa, La. , here the tip moth has been causing severe lossesfor the past few years to the reproduction of young pine. Loblollypines were found to be the favorite host, while slash pine was 'outslightly injured. Observations seemed to indicate that longleafpine was almost immune from this type of injury, its principal in-jury seeming to be a loss in the attainment of height. Observation;swere also made on a series of trap-tree studies that have been inprogress for the last two years, to determine the aggressiveness ofcertain barkbeetles and the condition most favorable for their at-tack and the development of their broods. On May 20 Messrs. Bate-hofer and St. George conferred -ith ?. D. Forbes, Director of the -Southern Forest Experiment Station, iew Orleans, La., on currentinsect problems in the South. It was learned that tip-moth injuryhas been noted in plantations all over the northern part of Louis-iana, especially for the past t 'o or three years, indicating thatthis injury is quite general in the State.

Comparative counts of resting mosQitoes were begunJuly & and the average number per house found underneath a groupof five tenant houses for three successive weeks was as follows:July S - 1,100; July 15 - 991; July 22 - 929. The average fortwo of these houses for which comparative records for previousyears are available were 977, 8(3, and 735 for the same dates -:hilein July, 192;, the average was 1 45, and in July, l92!4, only 22.although the records for this year are above normal they werenevertheless equalled several years ago as a result of excessiverainfall during the spring and summer. However, from general ob-servations made at Tallulah and elsewhere it was evident that theincrease of anopheles has been greater in other places than at--ound. Thile t he female anopheles under normal conditions usuallydo their biting after dark they have caused considerable annoy-ance during this overflow by biting during the daytime in build-ings or in shady places out of doors. The removal of most of thedomestic animals and the consequent lack of food for so many mos-quitoes is a probable explanation for this change of habits. A

report from Bear Lake, where mcsuitoes were said to be extremelynumerous, stated that Anopheles ..ere biting out of doors in brightsunlight, "rhich is a decidedly unusual occurrence.
