Vine mealybugs can cause severe damage in your vineyard:

  • Vine mealybugs (VMB) can deposit copious amounts of honeydew on grape bunches.
  • Honeydew serves as a substrate for black sooty mold.
  • VMB can infest bunches directly, making the grapes unfit for consumption.
  • VMB can transmit grape viruses.

After being contacted by concerned grape growers who realized the need to incorporate biological control into their pest control program, we began rearing Anagyrus pseudococci in 2010. This beneficial insect complements our Cryptolaemus beetles and gives grape growers an effective “one-two” punch to combat vine mealybug.

Anagyrus pseudococci provides up to 90% parasitism of vine mealybug in the San Joaquin Valley. This beneficial parasite is active late in the grape growing season and can reduce vine mealybug populations before the pest moves to the lower part of the trunk. We are raising the preferred strain of Anagyrus which was utilized in the UC research that showed the efficacy of this parasitoid on vine mealybug.
Some of the benefits of biological control include:

  • Decreases your dependence on pesticides
  • Eliminates much of your pesticide use reporting
  • Allows you to avoid REI’s, PHI’s, and MRL issues
  • Saves you money from reduced pesticide use
  • Increases sustainability

We suggest that implementing the two biological control options of Cryptolaemus and Anagyrus in your vineyard will allow you to decrease your dependence on chemical control agents and meet with your sustainable farming goals. Associates Insectary has over 80 years’ experience in the production of beneficial organisms and works hard to meet our growers’ needs as the agricultural industry evolves and changes.
