Research Specialization – integrated pest management. My research program studies strategies for integrated pest management of San Joaquin Valley citrus. We establish or verify economic thresholds for key pests, study the efficacy of natural enemies, 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 thrips and mites in nursery citrus, validation of degree-day units and pheromone traps for citrus cutworm monitoring, study of the effects of insect growth regulators on vedalia beetle a natural enemy of cottony cushion scale, and pesticide resistance monitoring of California red scale.
