  Pheromone traps against American Bollworm (Helicoverpa armigera, Lepidoptera: Noctuidae) were installed at 1.5 m from the ground in okra (Abelmoschus esculentus L.). First moth, in the field, was appeared during 7th and 6th weeks of traps installation each year 1995 and 1996, respectively. Maximum mean numbers of moths (11th and 7th) were captured during 9th and 7th weeks of traps installation, when the average temperatures were 28.38 and 25.78oC each year, respectively. A total mean number of 24 and 17 moths were captured during the two years of study respectively. The adult pest remained in the field till 11th and 4th August 1995 and 1996, respectively. The study strongly recommends the use of pheromones over pesticides against the said pest in okra.

  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°C, 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.

  Pheromone traps of American/cotton bollworm (ACBW) (Helicoverpa armigera, Lepidoptera: Noctuidae) were installed at 4 m from the ground in apple (Pyrus malus Linn., Rosaceae: Pomoidea) canopy in the two adjacent apple orchards in Quetta, Balochistan, Pakistan. Maximum capture was through the traps, hanged at the edges of the orchards. First moth, in the orchard, was appeared on 22nd (at 16.65 oC) and 8th March (at 12.00 oC) during 1995 and 96 respectively. Population climax of the moth was observed at 19.00 (32 moths on 7th April) and 18.75 oC (36 moths on 27th March) during 1995 and 96 respectively. During 1995 the pest remained in the orchard for 29 while in 1996 for 24 days. The study reveals that pheromone traps could affectively be used for the scouting/control of the said pest in apple canopy.
