Diseases have impacts on some natural insect populations such as western tent caterpillars that experience epizootics of viral disease at peak population densities. Insect diseases have also been developed as microbial pest controls and the most widely used of these is the bacterium, Bacillus thuringiensis (Bt). In the field, disease epizootics persist for a short time and selection on populations is relaxed as densities decline In agricultural situations, where microbial control is used, strong selection can result in the development of resistance. Our research has been directed at determining the genetic and physiological basis of resistance that we have found in populations of cabbage loopers, major pests of green house grown vegetables. In addition we are exploring the immune responses that allow insects to potentially overcome infection in the field.

疾病对一些自然昆虫种群有影响，例如在高峰种群密度时经历病毒性疾病流行的西方帐篷毛虫。 昆虫疾病也被开发为微生物害虫控制，其中最广泛使用的是细菌苏云金芽孢杆菌（Bt）。 在田间，疾病流行持续很短的时间，随着密度的下降，对种群的选择也放松了。在农业环境中，使用微生物控制，强选择可能导致抗性的发展。 我们的研究一直致力于确定抗性的遗传和生理基础，我们已经在绿色室内种植蔬菜的主要害虫卷心菜尺蠖种群中发现了抗性。 此外，我们正在探索使昆虫能够克服田间感染的免疫反应。
