Current Research Interests Research in my urban entomology laboratory is focused on understanding the behavioral ecology of Formosan subterranean termites and other social insect pests in order to develop new and improved control methods. My research philosophy is that better methods for control must ultimately be based on a more complete understanding of termite biology. Our control efforts are geared toward developing environmentally sound methods that take advantage of the social networking of these successful organisms. The role of juvenile hormone in caste regulation, how termites make foraging decisions, volatiles associated with termites and their nests, attractants and repellents of natural origin that can target termites or make wood inedible and fungi found useful to termites in the control of fungi that compete for cellulose are directions my laboratory is currently undertaking. In addition, I teach 4 university courses and a summer course to pest control operators. ^Back to top Selected Publications: Fei, H., and G. Henderson, 2006.
