RESEARCH1. Host-plant Volatile Attractants

Plants emit volatiles that can serve as important cues for insect herbivores in host finding. Because plant volatile compounds play a critical role in the insect’s life, they can be a useful tool in insect pest management programs. Plant volatiles can be used as attractants in traps for monitoring and mass-trapping insect pests.

Prior to joining Rutgers University, I worked with a team of scientists from the USDA-ARS to develop attractants for the western tarnished plant bug, Lygus hesperus, and with scientists from the USDA-Forest Services and Michigan State on the development of attractants for the emerald ash borer, Agrilus planipennis. Currently, we are studying the emission of volatiles from vegetative and flowering blueberries and cranberries and the behavioral and antennal-electrophysiological responses of insects to these volatiles.

A laboratory for the study of plant volatiles and insect behavior has been established at the Rutgers Marucci Blueberry and Cranberry Research and Extension Center. This laboratory accommodates equipment for the collection and analyses of plant volatiles, electro-antennographic detection, and insect’s behavioral response to plant volatiles.
