We are finding all life stages of VMB at Carneros and Howell Mountain sampling sites. We found all VMB under the bark.
We found evidence of parasitism and predation at the Carneros site--both empty and full mummies, and mealybug destroyer beetle larvae.
Careful monitoring of VMB is highly encouraged. Large populations with overlapping generations can be very challenging to control. Multiple, early intervention strategies can keep VMB populations low. Rotation of insecticidal materials is also highly encouraged to decrease the potential for resistance to develop and to protect products for future use.
