Understanding distribution of Drosophila suzukii and its life cycle, ability to overwinter, best monitoring techniques, rearing of, and capability to increase in Oregon's fruits.

Taking a closer look at mealybugs, the vector of Grapevine leaf roll virus (GLRv) and mites, the contributor to short shoot syndrome (SSS) found in Oregon wine grapes
