Abstract The continuous use of gossyplure‐baited traps in 1974–1975 for monitoring infestations of the pink bollworn moth in cotton fields succeeded in reducing the percentage of infested bolls to less than 5% in the Hagilboa and Beth‐She an regions of Israel. The average number of insecticidal treatments necessary to control the pest was likewise reduced from 5.8 in 1974 to 1.64 in 1975 in Beth‐She’ an and from 2.9 to 2.21 in Hagilboa. The monitoring threshold of 8 males captured per trap per night to determine the need for pesticide treatment, instituted in 1975, proved, as expected, to be a less accurate yardstick than the threshold of 5 males per trap per night previously recommended. Crude or distilled cottonseed oil was more efficient for use in the trap cups than the aqueous detergent solution used heretofore, and the traps themselves were considerably improved by providing a plastic rooflet above the cups.
