Abstract
The present invention features a method and composition for attracting a target insect to a selected location. The invention is based on the discovery that negatively charged chitosan polymers, e.g., NOCC, have advantageous properties for use in a semiochemical delivery system for releasing a volatile semiochemical at a substantially sustained rate over an extended period of time to attract a target insect to a selected location. The present invention may be used for monitoring a target insect by capturing the insect. Alternatively, the present invention may be used for the management of a target insect by disrupting mating patterns of such insects.
