Dr. Gill's research focuses on three major pests of tomato; twospotted spider mite, western flower thrips and sweetpotato whitefly. Currently, the management of these major pests relies heavily on pesticides that increase the risks of resistance development and cause secondary pest outbreaks. Dr. Gill is evaluating tomato lines and hybrids for resistance to spider mites, thrips and whiteflies, with the goal of developing an ecologically based pest management tactic that alleviates concerns associated with reliance on pesticides. He is also interested in evaluating the compatibility of resistant tomato lines with natural enemies of these major pests in the tomato production systems.
