My responsibilities focus on the evaluation and management of arthropod induced stress on soybean and tobacco. These two crops rank among the top row crops in Georgia agriculture, and collectively are worth over $150 million annually. Arthropod pests are a major limiting factor in production of these crops in Georgia. My current soybean entomology research is investigating the impact of transgenic soybeans (herbicide tolerant and Bt) on insect abundance and crop damage, studying the effects of early soybean production systems on the abundance of arthropod pests, and examining soybean resistance to stink bug seed damage and caterpillar defoliation. My current tobacco research focuses on studying the population dynamics of thrips and their impact on the incidence of tomato spotted wilt virus, utilizing ELISA techniques to confirm thrips vectors and plant host reservoirs, developing insecticide control strategies that are less detrimental to the environment, and refining the economic injury levels for insect pests.
