Gossyplure, the pink bollworm, Pectinophora gossypiella (Saunders), sex pheromone, has been readily accepted an effective trap bait. Pheromone-baited traps have been important tools for pink bollworm detection, monitoring, and survey. They have the potential for further use as decision-making instruments to determine the need for control action in integrated pest management programs. Therefore, we initiated studies at Phoenix, AZ, in 1980 to determine the relationship between male moth trap catches and pink bollworm infestations. Some of these data have been published previously (Henneberry and Clayton 1982). We also studied the relationship of early-season male moths emerging from pupae formed by overwintering larvae and early-season infestation in flowers and bolls during the first and second fruiting cycles in 1983 in the Palo Verde Valley, CA. The present paper is a report of progress of these studies.
