Introduction
The use of pheromone traps to monitoring the vine mealybug, Planococcus ficus and its main parasitoid, Anagyrus sp. nr. pseudococci
in Douro Wine Region
- Transmission of Grapevine Leafroll Viruses
- Vine decay - directly due to its feeding activity
- indirectly due to the honeydew contamination of leaves and grape
clusters and development of sooty mold
Vine mealybug (VMB) Planococcus ficus
Usually it overwinters in trunk (under the bark )Biology

It can be also go on vine roots
and weeds
During spring and early summer, mealybugs move to shoots, leaves and clusters
