Extension Statement
As the entomologist in charge of field crops at the University of Kentucky, my extension programs focus principally on wheat, corn, and soybean crops for the entire state. However, as the only member of the Department of Entomology outside of the Lexington campus, I am active supporting my clientele with entomological concerns related to vegetables, fruit, ornamentals, and arthropods invading structures and of importance for human health in western Kentucky.
Clockwise starting from top: infected aphid, rice stink bug in barley, slug damage in soybeans, Dectes stem borer larva, and adult.
Applied Research
My applied research is based in building teams among specialists from various disciplines and organizations. My research program also incorporates the mentoring of undergraduate and graduate students to conduct research on issues relevant to the farmers of Kentucky. Topics currently evaluated in my program are:
- Aphid presence in the fall and spring, insecticide applications, and BYDV infections (funded by the Kentucky Small Grains Promotion Council)
- Diversity, identification and damage caused by stink bugs in Kentucky soybeans and corn (MSc. Thesis: potential student Y. Gonzalez, funded by KY Soybean Promotion Board)
- Slug damage and cover crops, insecticide seed treatments, and ground beetle relationships (not funded)
- Management of Brown Marmorated Stink Bugs: Halymorpha halys in Kentucky (MSc. Thesis: L. Fann, funded by USDA-NIFA)
- Biology, abundance, and damage caused by Dectes stem borer (MSc. Thesis, I. Gomes)
- Distribution and phenology of Kudzu bug in Kentucky.
- Ambrosia beetles: phenology and management (funded by KY Department of Agriculture)
- Sugarcane aphid on grain, forage and sweet sorghum (not funded)
Current graduate students
- Izabela Gomes, MS Student, co-advised with Ric Bessin
- Lauren Fann, MS Student, co-advised with Ric Bessin
- Yaziri Gonzalez, MS Student, co-advised with Ric Bessin
