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. Examples of research projects include: release of predatory mites for control of thirps and mites in nursery citrus, validation of pheromone traps and degree-day unites for citrus cutworm and citrus peelminer, studying the effects of insecticides on the predatory vedalia beetle (a natural enemy of cottony cushion scale) and pesticide resistance monitoring of California red scale and citricola scale.
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.
