Abstract
The vine mealybug is a severe, new vineyard pest in California.
Typical treatment relies on application(s) of organophosphate or carbamate insecticides.
We investigated the use of less-disruptive insecticides, releases of natural enemies and mating disruption as alternative control strategies.
Results show a systemic application of imidacloprid or a foliar application of buprofezin reduces crop damage.
Inoculative release of a parasite (Anagyrus pseudococci) also reduced crop damage; currently, this natural enemy is not commercially available.
Similarly, mating disruption using a synthetic sex pheromone can suppress mealybug populations, but the sprayable formulation is not yet registered in the United States.
There is great potential in both augmentation and mating disruption, which are being further developed for commercial use.
