Extension Entomologist / Entomologist in the Agricultural Experiment Station
University of California, Davis
Davis, CA


Larry Godfrey is an Extension Specialist in the Department of Entomology at U.C. Davis. He has held his position since 1991. He conducts research on applied ecology and integrated management of arthropods affecting field and vegetable cropping systems and delivers research-based pest management information to clientele. He received his B.S. and M.S. degrees from Purdue University in 1978 and 1980, respectively and his Ph.D. from the University of Kentucky in 1984. Following a brief employment stint with a private company, he returned to academia first with the University of Nebraska followed by U.C. Davis. He has conducted research on several invasive insect and mite pests (silverleaf whitefly, panicle rice mite, rice water weevil and others), some of which are now fully established in California and are significant annual pests. He has authored approximately 120 publications and about twice that number of limited-distribution, regional articles. He served as President of the Pacific Branch of the Entomological Society of America in 2008 and received the Pacific Branch Award for Excellence in Integrated Pest Management in 2005. He serves as Associate Technical Editor for the Journal of Cotton Science.

Personal Statement

“Growing up on a farm in Indiana, I saw first-hand the ‘battles’ that farmers and homeowners face trying to produce crops and grow landscape plants in competition with insects. I became fascinated with insects through the typical ‘bug in a jar’ hobby. A county natural resources field day cultivated my interest in entomology and this led to enrollment in the 4-H entomology project. By the time I was several years into the 4-H project, I was transporting a dozen wooden collection boxes full of pinned insects to the county fair. My first summer job involved surveying for Japanese beetles as they progressed across Indiana. This was an invasive insect in the Midwest in the mid-1970s; this same insect is of serious concern now in California as an invasive pest that could damage many crops (such as grapes) and ornamentals (such as roses).”

Conflict of Interest Statement

I have no personal financial stake in any actions that CISAC is likely to undertake. I have received funding from the California Department of Food & Agriculture totaling approximately $50,000 over the last 10 years for research on pest management issues. I do apply for and receive funding from other governmental agencies, such as California Department of Pesticide Regulation, U.S. Department of Agriculture, and U.S. Environmental Protection Agency, in support of my research program. I also receive funding from commodity groups in response to research proposals I submit, and I have also received unrestricted gift money from industry, which I use to help fund my staff.
