Abstract
Large-scale field tests were carried out to evaluate the integrat­ed use of insecticides and pink bollworm pheromone formulations for controlling P.gossypiella in Zagazig, El-lbrahemya, and Diarb Nigm dis­tricts, Sharkia Governorate. Results obtained are summarized as follows : 1- Rope PBW formulation There were no significant differences in male moths catches in funnel traps in test fields comparable with each other until the 2nd week of June. Then, trap catches in the field treated with PBW-ROPE dispens­ers were virtually eliminated (Zero moths) until September 9th in com­parison with the untreated fields. Analysis of variance of male moths caught in pheromone traps showed that there were significant differenc­es in male moths between the different treatmets. As for the percent­age infestations of cotton bolls by P.gossypiella larvae, pheromone-insecticides treatment, revealed the lowest infestation in comparison with insecticides treated and untreated fields_ Analysis of variance be­tween the male moths caught in the traps baited with Pectinophora pheromone in the different treatments showed that there was no corre­lation between the number of male moths caught and the percentage of infestation in pheromone-insecticides treated plots. While in insecticides treated and untreated fields there was a clear positive correlation be­tween the male moths and the percentage of boll infestation.
