ABSTRACT

Four experimental formulations of synthetic gossyplure were tested in the fields in Southern California, Central Arizona and West Texas. Results indicate that these formulations suppress trap capture, an indicator of mating activity, of sterile and native pink bollworm for as long as 47 days. Longevity of the pheromone varied widely among the tests based on location, time of year, and rate of application. Results were promising enough that further testing of these formulations is planned for early season tests in 2004.
