Abstract

In Egypt. the honeydew moth, Cryptoblabets gnidiella Miller (Lepidoptera: Pyralidae) is a polyphagous serious pest in fruit orchards as well as in vegetable and field crops. The seasonal abundance of moths population was studied In mango, grapevine and citrus orchards at She-bin El-Kanater, Kalubia Governorate using sex pheromone traps during two successive years, 1997 and 1998. Moths started activity from the 2nd half of April, 2ndhall of May and 1st or 2nd half of October in man­go, grapevine and citrus orchards, respectively. Two to four, three and three peaks of moths activity were recorded in the respective orchards. but the latest peaks were the largest owing to the fruit maturity and ri­pening.
