Research Interests

Insect behavior mediated by semiochemicals, including pheromones, host plant kairomones, and feeding attractants. Pheromone studies focus on sex attractants. Host plant kairomone studies include the isolation and identification of host attractants and the effects of insect experience on host finding behavior. Feeding attractant studies are on wasp and moth responses to microbial fermentation odors.

Development of applications of semiochemicals in pest management, both as a means of monitoring and detecting pest populations and as a means of population reduction.

Presently, these interests include the study of codling moth, Pandemis leafroller, Lacanobia fruitworm, alfalfa looper, cabbage looper, western yellowstriped armyworm, corn earworm, Limonius wireworms, pear psylla, and social wasps.
