As a chemist interested in biological and agricultural systems, I have studied chemicals that affect insect behavior. My laboratory has identified insect pheromones and other semiochemicals, including the boll weevil pheromone, which is a key component of the boll weevil eradication program. We also investigated the biochemical mechanisms by which chemical signals are produced and released by insects, and studied the behavioral responses, including learned responses, of insects to chemical cues.
More recently, we have been investigating the interactions among herbivorous insects, their host plants, and their natural enemies. We found that plants damaged by caterpillar feeding synthesize and release volatile chemicals. Small wasps use these released volatiles as cues to locate and parasitize the caterpillars. The chemical defenses of the plant are induced by a compound, which we identified and named volicitin, in the oral secretion of the caterpillars. We are now investigating the biochemical mechanisms by which volicitin triggers the plant chemical defense, the source of volicitin in the caterpillars, its role in insect metabolism, the structures of similar molecules in other insect species, and the responses of the parasitic wasps to plant volatile chemicals. Emphasis is on developing fundamental knowledge and principles that can be applied in environmentally safe pest management programs.
