Pheromone Technology for the Control of Helicoverpa armigera in Okra
Muhammad Faheem Malik,
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.
