ABSTRACT
Gossyplure, the true sex pheromone of the pink bollworm, was identified in 1973 and proved to be a much more effective mating disruptant than hexalure. Large-scale field trials in which gossyplure was used as a mating disruptant for the pink bollworm also were conducted in cotton in Arizona by Conrel, FRL-Albany International, Norwood, Mass., during the 1976 growing season. Only approximately 15% of the fields in this test required any insecticide, and the number of applications of insecticide in the fields that did require treatment was reduced 50% to 60% from the number to protect the control field, which was treated conventionally. The knowledge gained from the test is widely applicable to a broad spectrum of insect pests of field and vegetable crops in areas where integrated pest management programs involve conventional pesticides, biocontrol agents, and good cultural practices.
