Conventional Management for BMSB

• ARM or full block sprays of broad spectrum materials (Rice et al. 2014; Lee 2015)

Conventional Management for BMSB

• ARM or full block sprays of broad spectrum materials (Rice et al. 2014; Lee 2015)

• Not sustainable in the long term

Recent Advances with Pheromones

• BMSB aggregation pheromone identified as two stereoisomers of 10,11-epoxy-1-bisabolen-3-ol (Khrimian et al. 2014)

• Attraction is synergized when combined with methyl decatrienoate (Weber et al. 2014)

Methyl decatrienoate (MDT) Active components of 10,11-epoxy-1-bisabolen-3-ol

Attract-and-Kill as Alternative Strategy

Attract-and-Kill as Alternative Strategy

Preliminary Work with AK

• Over 6 days, killed ~28,000 adults and ~5,000 nymphs at trees with high dose of pheromone (Morrison et al. 2016)

• High retention capacity of AK trees and low spillover into rest of orchard (Morrison et al. 2016)

•On 10 farms in 2015 & 2016

Commercial Attract-and-Kill

•On 10 farms in 2015 & 2016

•Two treatments: AK vs. grower std.

Grower Standard Attract-and-Kill Block

•On 10 farms in 2015



•On 10 farms in 2015


•Safeguard with spray triggered by monitoring trap

2016 Summary

• At harvest, statistically equivalent frequency and severity of damage in AK block interior trees compared to grower standard

• Equivalent control in perimeter trees to grower std

• Killing >40 adults per week, per AK tree during late season

Economics Comparisons of Attract-and-Kill

Attract and Kill Standard

Take Home Messages

• Attract-and-kill is an effective pest management strategy

• But: not cost effective

• Unless lure price or deployment strategy can be significantly altered, no grower will adopt this
