Biography

Research Statement
My research and extension program stuies strategies for Integrated Pest Management (IPM) methods to manage arthropod pests of citrus in the San Joaquin Valley of California. We establish or verify economic thresholds for key pests, study the efficacy of natural enemies, maximize the use of biological and cultural control methods, develop pheromone trapping systems, screen the efficacy and selectivity of new insecticides and test pests for resistance to insecticides.  In recent years I have focused on invasive pests such as Asian citrus psyllid and pests of export significance such as Fuller rose beetle.  

As of June 2006 I am also Director of Lindcove Research and Extension Center in Exeter California. This 175 acre Center supports research projects on citrus breeding, horticulture and pest management.

Education

Ph.D. Entomology, UC Berkeley. 1985
M.S. Entomology, Purdue University. 1980
