Male Disruption Pheromone as a New Strategy in Controlling Pink Bollworm, Pectinophora gossypiella (Saunders) in Egypt

Moawad, G.M., Z.R. Sawires, M.W. Watson and A. E. Gaber


Large scale field tests were carried out in EL-Minia (6722 ha.), Assiut (5042 ha.) and Dakahlya (1050 ha.) to estimate the efficiency of PB-ROBE pheromone (polyethylene tube, hung on plant twig by hand) in suppressing and controlling the pink bollworm populations in cotton fields.

The results indicated that the reduction in the number of the male moths captured per trap reached 90-100% i the pheromone treated areas compared with insecticide treated areas. Large scale application of pheromone resulted in decreased the boll infestation percentages from 1.4, 2.8 and 3.1% to 0.8, 1.02 and 1.0% in Assiut, El-Minia and Dakahlya respectively. Consequently, the number of insecticide applications used to control the pest decreased by about 50-75% in the pheromone treated areas.
