Pheromone traps against American Bollworm (Helicoverpa armigera, Lepidoptera: Noctuidae) were installed at 01 m from the ground in tomato (Lycopersicun esculentum, Solanaceae). First moth, in the field was appeared during 04th and 03rd weeks of transplantations each year (1995-96) respectively. Maximum mean number of moths (11 and 09) were captured during 11th and 08th weeks of transplantations, when the average temperatures were 28.38 and 26.30 degree centigrade, each year respectively. A total mean number of 63 and 45 moths were captured during the two years of study respectively. The adult pest remained in the field till the crop was uprooted. The study strongly recommends the use of pheromones than pesticides against the said pest in tomato.
