Pink Bollworm: Trap Tests with Gossyplure123

Abstract

Studies related to control of the pink bollworm (PBW) by trapping were conducted on an 80-ha farm located in Phoenix, AZ. Initial laboratory studies of trap efficiency lead to the incorporation of 10% dicrotophos into Stickem^® used in traps (ca. 13% increased kill compared to traps with Stickem only). During the period April 29 to Sept. 15, 1975, a trapping program on 36 ha of cotton resulted in the capture of ca. 30,000 ♂ PBW. Nine percent of the acreage attained 10% or greater boll infestations during the season compared to 45–100% for the preceding 1972–74 seasons. Early fruiting cotton (plots of 4 rows × 7.6 m) was no more attractive to PBW than surrounding, less developed cotton. Early season trap catches indicated that male moths congregated in cotton fields regardless of where they emerged.
