Abstract: 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.
