| Abstract | ||||
| Field experiments at Sharkia governorate (El-Khattara region) carried out to study the ecology of Hemiberlesia lataniae (Signoret) Homoptera: Diaspididae) on fig trees during two successive seasons 1994 and 1995. Obtained data showed that three peaks were recorded in January, April and November during the two seasons. The highest one was in January for both seasons, with more number in the first season. The main parasitoids on Hemiberlesia lataniae were Aphytis sp. and Aspidiotiphagus sp. Percentage of parasitism during 1994, had two peaks of activity in July and September, while one peak only in June was recorded in 1995. Parasitism was more higher in spring and summer than in autumn and winter. Three overlapping generations were recorded in both seasons, the first, required about three months, the second generation required about seven months, and the third was about two months. The second generation was the weakest one, compared with other generations. Combined effect of temperature and sunny shine had a positive highly significant effect, while R.H. % and sunny shine showed a negatively significant effect on all stages. | ||||
