My research revolves around integrated pest management (IPM) using cultivar resistance and a blend of cultural, biological, and insecticidal control tactics. I have collaborative research with plant breeders and molecular biologists in the Applied Genetics Technology laboratories in the College of Agricultural and Environmental Sciences, and my students and I have been involved in:
- Mapping of insect resistance (IR) genes in soybean using marker assisted selection. We have identified at least five IR QTLs (quantitative trait loci).
- Developing insecticidal transgenic soybean and canola expressing a Cry 1Ac toxin derived from Bacillus thuringiensis (Bt).
- Developing high yielding soybean cultivars pyramided with Bt and one or more native resistance genes.
- Vulnernability of soybean possessing value-added traits such as enhanced oil and protein quality, vitamins, enhanced taste, etc.
- Evaluating the genetic interaction of insect resistant genes and negative agronomic traits, particularly reduction in yield.
- Using soybean cultivars pyramided with insect resistance with selected cultural, biological, and insecticidal control tactics in cost effective IPM programs.
I also have collaborative research with industrial plant breeders in developing insecticidal transgenic maize and cotton. Thus, my students and I have access to some of the most advanced insect-resistant crop lines in the world to conduct thesis research on IPM and ecological interactions of these plants with pest and beneficial insects.
I have always been interested in the influence of cultural practices on creating environments for increased or decreased hazard for pest problems in crops, particularly use of conservation tillage. We were among the first to study insect and natural enemy interactions in conservation tillage systems and have multiple field research projects every year around Georgia with maize, soybean, and cotton that my students utilize in their thesis research. I also do considerable research in development of new insecticide technologies and involve my students (particularly my MPPPM students) in these projects. My philosophy is that whether you approve or disapprove of pesticides you should have at least some experience using them in practical IPM programs as a foundation for forming an opinion, and my students have this opportunity.
Iteach Insect Pest Management, Integrated Pest Management, and Pesticides and Transgenic Crops. I am the graduate coordinator of the Master of Plant Protection and Pest Management Program (MPPPM) and advise students in the undergraduate Integrated Pest Management certification program at UGA. The MPPPM program is a professional masters degree program between the departments of Entomology, Crop and Soil Sciences, and Plant Pathology. The program is designed to produce graduates with comprehensive, multidisciplinary training in Integrated Pest Management (IPM) of insect, plant disease, and weed pests of commercial and home commodities. MPPPM graduates are trained for employment as IPM professionals in the pest control industry, pesticide and fertilizer services, cooperative extension, and regulatory agencies. The goal of the MPPPM program is to train students to be proficient in solving the types of pest management problems routinely encountered by growers and other agricultural professionals, as well as urban pest control. IPM using a blend of pest control strategies including pesticides, transgenic crops, cultural operations, and biological control is stressed in classwork. The MPPPM program is not a research-oriented degree, but graduates have successfully pursued Ph.D. degrees related to IPM. There is no thesis requirement in MPPPM, but an IPM-oriented internship is part of the program of study.
