Areas of Specialization/Research

Seth Johnson is the author of more than 80 publications (five book chapters and refereed bulletins, 40 in refereed journals, 10 refereed invited proceedings and 28 technology transfer papers and published abstracts), earlier leading a broadly based research program on the ecology of Lepidoptera row crop pests and now biological control of insects and aquatic weeds. Field and laboratory ecological and other studies were conducted on spatial distribution, life tables, parasites, phase variation, reproductive biology, feeding behavior, population genetics, mating behavior, flight potential, and migration of multiple species of Lepidoptera. Currently his research is focused on the biological control of red imported fire ants, citrus pests and aquatic invasive weeds and the biology and ecology of the agents involved.

Service includes work on numerous university, professional and national organization committees, as well associate editorship for the Entomological Society of America. International service has included assignment in Jamaica on an USAID institutional development project at the College of Agriculture and leading a Study Abroad group on Tropical Agriculture in Jamaica.

In addition to serving as major professor for 11 graduate students (and on 30 committees), formal instructional courses taught in the College of Agriculture include a graduate course in insect population ecology, the entomology section of a team-taught course in introductory pest management and the biological control half of a graduate course in insect pathology and biological control.
