My research focuses on the development of ecologically-based insect pest management systems. Research studies include classical biological control, augmentation programs, insect-plant interactions, use of least-disruptive insecticides and the biology of natural enemies.

Most of my research programs have an extension component because I work closely with the commodity boards and other UC Cooperative Extension personnel. Moreover, the close collaborative ties with UC Cooperative Extension agents, Pest Control Advisors and leaders in farm management has helped to extend the developed information to a wider audience.

Each of California’s varied grape regions has different cultural practices, economic structures and pest problems providing an exciting challenge to develop programs that can be used for winegrape growers in Napa and table grape growers in the Coachella Valley. Recent research has concerned mealybug pests, including the invasive vine mealybug. Closely connected to this project is development of sustainable ant controls. In two collaborative vineyard projects, we are working with Dr. Nick Mills on changes in mite populations and with Dr. Rodrigo Almeida on the importance of leafroll viruses.

A new research project for the laboratory concerns sharpshooters, such as the glassy-winged sharpshooter, and their role in the transmission of the bacterium that causes Pierce’s disease in grapes and almond leaf scorch in almonds.

Sustainable agriculture for stone fruit (peaches, plum, and nectarines) has advanced during the past decade through the implementation of "pheromone confusion" and use of novel insecticides for moth pests. One of the last challenges is understanding biological control. We have recently worked on the biology of parasitoids that attack San Jose scale and (lepidopteran) moth pests.

Pistachios and almonds are important California crops. A number of hemipteran (or true bug) and moth pests native to North America have discovered their leaves and fruit are quite tasty and part of my research program is directed towards these pests.

A classical biological control program has been undertaken for the olive fly, a newly invasive species in California. We are collaborating with researchers in California, Hawaii, South Africa, and France by quarantine screening parasitoid species to determine their potential to control the olive fly.

Another classical biological control project is targeting pests of the lemon gum and spotted gum Eucalyptus, which are valued as ornamental trees in southern California. We are working with Timothy Paine (UC Riverside) to import and screen parasitoids of the spotted gum psyllid, a recently invasive species, which were recently collected in Australia.

Similarly, foreign exploration in China is being conducted to find natural enemies of the Asian wooly hackberry aphid. Work is conducted in collaboration with Andrew Lawson (CSU Fresno)
