The International Society of Chemical Ecology (ISCE) exists to promote the understanding of interactions between organisms and their environment that are mediated by naturally occurring chemicals. Research areas covered by this include the chemistry, biochemistry and function of natural products, their importance at all levels of ecological organization, their evolutionary origin and their practical application.My particular interest in chemical ecology is in the application of sex pl~cronionesto control Helicoverpa armigera in cotton and other crops.
