Research Specialization

My research group conducts basic and applied research aimed at developing environmentally and economically sustainable Integrated Pest Management programs.  Currently the lab is studying the biology, ecology, and management of the carob moth, a key pest of ripening date fruit.  This research is centered on elucidating the seasonal life cycle of moths on dates, the impact of currently used pesticides, the natural enemy complex that exists in the date garden, and mating disruption with a pheromone mimic.  We also are studying the management of the date mite using biological and chemical control methods integrated with new sampling strategies.  Additionally we are conducting research on the newly introduced Bagrada bug, which is causing devastating losses to vegetable growers in the desert regions of southern California and Arizona.  We have studied the host range of this pest and are beginning to look at the seasonal biology and temperature-related developmental rate.  Finally, we continue studies on the epidemiology of arthropod-borne plant pathogens and are studying sharpshooter-vectored Xylella fastidiosa, the causal agent of Pierce’s disease of grapevines.
