Abstract
This study was carried out to estimate the effect of virus infection on the silver leaf whitefly, Bemisia argentifolii (Bellows and Perring). The insect spent three different generations for this study. The incubation period of insect which did not significantly affected in this study ranged from 2 – 5 days for the different insect state and generations. However, there were not clearly observed differences between the different insect life cycle of the two insect sexes in the different three generations. The lowest duration period in different tested replicates was recording 11 days in case of healthy insect state in the third generation and the highest value was recorded 18 days. However, the longevity period of the adult female was highly significant between the different insect three generation and this effect was not recorded between the different healthy insects and infected once. The lowest longevity period of adult males was recorded 8.2 days in the case of healthy insects of the third generation. But the longest longevity duration period of insect 19 days was determined when the adult females were exposed the infection with the virus.
