ENTO 3740 Insect Pest Management (Fall Semester) (syllabus)
I have a 75% research appointment. My research program focuses on the integrated pest management (IPM) of grain, forage and alternative agronomic crops. I have responsibility for insect pest management of all the smaller or minor agronomic crops in Georgia with the exception of soybean. Collectively these crops represent a significant component of Georgia’s agricultural makeup. The objective is a mission-oriented effort to develop and improve biologically-based pest management systems for grain, forage and alternative agronomic crops with relevance to Georgia agriculture. Specific areas of research include:
1. Biology, management, and sampling of insect pest of grain, forage and alternative agronomic crops. Commodities include corn, wheat/cereal grain crops, grain sorghum, millet, sunflower, canola, perennial legume forage crops such as alfalfa, and winter and summer annual forage crops. Efforts include quantifying damage loss relations of pest injury and crop loss of yield and quality, development and use of economic thresholds, development and refinement of sampling procedures for key pests, examining the effect of cultural practices such as tillage, planting time, seeding rates, etc., on pest populations, and assessment of novel pesticide technology for grain and forage crops.
2. Plant resistance to insects. Recent efforts continue to cooperate with the cereal crop breeding program at UGA to develop wheat cultivars with new and effective resistance to Hessian fly. A related project examined sources of resistance for control of leaf curl mite in soft red winter wheat.
3. Plant response in insect stress and effect of insect feeding on plant physiological processes. Research has focused on understanding the effects of insect feeding injury on plant gas exchange processes in selected insect/plant systems. Previous studies have examined the effect of feeding injury by azalea lace bug on gas exchange of azalea, whitefly injury on gas exchange in poinsettias, and feeding injury by thrips on photosynthetic processes of tomato.
4. Biological control of weeds using insects. Past efforts have involved the release, monitoring, and documentation of impact of exotic weevils released for control of musk thistle and related thistle species in Georgia. No new projects are currently ongoing.
Extension / Outreach
Extension efforts (10% appointment) delivers timely research results on insect management of grain, forage, and alternative crops to county agents, pesticide dealers, crop consultants, and growers through traditional training sessions and grower meetings. Information also is delivered via annual crop production guides both in print and web format. Additionally pesticide recommendations are updated periodically in the Georgia Pest Management Handbook. My overall goal is to provide timely information to county agents, agriculturalist, crop consultants and growers of grain and forage crops that maximizes the efficacy of insect pest control while minimizing costs and environmental contamination by pesticides.
