Gossyplure is currently used for detection and monitoring of the pink bollworm, Pectinophora gossypiella (Saunders), as well as a disruptant in the Western U.S. cotton growing areas. As a monitoring tool, formulation is less important than the quality of gossyplure used as an attractant. Significant differences in attractiveness exist between batches of gossyplure available. Success with gossyplure as a disruptant has been variable. Major success as an area-wide management tool has been achieved in the Coachella Valley of California using treatments of gossyplure in 1986 and a combination of gossyplure and sterile insects in 1987. Gossyplure is the backbone of this approach and utilizes a high rate single application for disruption.
