| Inhoud: |
During the growing season in 1975 traps baited with (Z,E)-9,11-tetradecadien-l-ol acetate (9,11-TDDA), the natural sex pheromone of Spodoptera (Prodenia) littoralis, were distributed in safety belts around 5,000 dunams of cotton, alfalfa, and stonefruit crops in the Upper Galilee and 1,500 dunams of cotton, alfalfa, and peanuts in the Beth-She'an Valley of Israel. Other unprotected crops in the surrounding areas served as controls. A total of 219 traps at Neot Mordechai caught almost 300,000 male S. littoralis moths during the growing season (June-September). PeaV captures at Neot Mordechai occurred in August, whereas optimum captures at Beth-She'an occurred in September. Total seasonal average captures per trap were 1300 in the Upper Galilee and 350 in Beth-She'an, the latter reflecting a much lower population density. In all experimental areas protected by the pheromone traps the number of insecticidal treatments necessary to control crop damage was much lower than the number of treatments required in control areas. |
