Research:

As a chemist interested in biological and agricultural systems, I have studied chemicals that affect insect behavior as well as those that induce defenses against insect herbivores in plants. My laboratory has identified insect pheromones and other semiochemicals, 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 insect herbivore feeding synthesize and release volatile organic chemicals. Small wasps use these released volatiles as cues to locate and parasitize the caterpillars. The chemical defenses of the plant are induced by compounds in the oral secretion of the caterpillars. We have identified three different classes of elicitor compounds from different species of herbivores. We are investigating the biochemical mechanisms by which some of these, fatty acid-amino acid conjugates, trigger plant chemical defenses. We are also investigating the mechanisms by which plants perceive and respond to volatile organic compounds from neighboring damaged plants. Emphasis is on developing fundamental knowledge and principles that can be applied in environmentally safe pest management programs.

Research Interests

Chemical Ecology

Insect pheromones and other semiochemicals, biochemistry of signal production and release in plants and insects, behavioral responses of insects to chemical cues, interactions among herbivorous insects, their host plants, and their natural enemies, biochemistry of insect saliva and regurgitant, environmentally safe pest management.

Honey Bee and Pollinator Research

Dr. Tumlinson and his students are investigating the chemical ecology and behavior of the small hive beetle, a recently introduced pest of bees.  The small hive beetle is attracted to volatile organic compounds, including the honey bee alarm pheromone.  Several of these attractive compounds, including the alarm pheromone, are produced by a yeast, which is associated with the beetle and thrives on pollen in the hives.
