Abstract
Field studies were conducted under different conditions of Sharkia Governorate (El-Khattara region) to study the ecological aspects of Parlatoria oleae (Colvee) (Homoptera: Diaspididae) on olive trees during two successive seasons 1994 and 1995. The obtained data showed that three peaks of activity of Parlatoria oleae, in January, April and August in outer zone and in January, March, August in inner zone in the first year 1994 and in February, August, October in outer zone , and in January, March, August in inner zone in the second year 1995. The highest peak was recorded in January for all zones during the two years except outer zone, which recorded in February1995. For both years three overlapping generations were recorded in inner zone, while in outer zone two overlapping generation were showed. The powerful generation was the last generation for both zones during two years. The total percentage of parasitism in inner zone was higher than outer one in both years. Aphytis sp., Merietta connecta and Merietta picta were the main parasitoids on P. oleae. Temperature and sunny shine has almost positive significant effect on all tested stages, while R.H % with sunny shine had a significantly negative effect.
