Gary L. Leibee

(100% Research)

1. Education

• B.S., The Ohio State University, (Entomology), 1974
• M.S., The Ohio State University, (Entomology), 1975
• Ph.D. University of Kentucky, (Entomology), 1979

2. Employment

• Associate Professor (1985-present) U. of Florida
• Assistant Professor (1979-85) U. of Florida
• Research Specialist (1979) U. of Kentucky
• Graduate Research Assistant (1976-79) U. of Kentucky

3. Research Responsibilities

• The primary job responsibility is to conduct research to develop pest management strategies for fresh market vegetables (60%) and woody landscape ornamentals (40%) in Florida.
• The vegetable entomology program is focused around insecticide resistance management. The woody landscape ornamental program involves biology and control of insect pests of commercially grown trees and shrubs.

4. Accomplishments

• Documented cyromazine resistance and determined its mode of inheritance in the dipterous leafminer, Liriomyza trifolii.This information was instrumental in developing a strategy for managing resistance in the leafminer in celery.
• Documented resistance to fenvalerate, methomyl, and Bacillus thuringiensis subsp. kurstaki in the diamondback moth, Plutella xylostella, in Florida.This information contributed to a change in use of insecticides on cabbage in Florida which resulted in lower and more manageable infestations.
• The magnolia root borer, Euzophora magnolialis, was discovered to be causing extensive damage to commercially grown magnolia.Results of biological studies of the magnolia root borer contributed to the development of a management strategy for this insect.
