Abstract : In Egypt, the honeydew moth, C. gnidiella (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 Shebin El-Kanater, Kalubia Governorate (Egypt) using sex pheromone traps during two successive years, 1997 and 1998. Moths started their activity from the 2nd half of April, 2nd half 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 last peaks were the highest due to fruit maturity and ripening.
