Abstract
Development and reproduction of the cotton whitefly, Bemisia tabaci (Gennadius) were studied on aubergine, tomato and potato under laboratory conditions (30°C and 55% RH). Total life cycle from egg to adult was 14.9, 20.0 and 14.2 days on aubergine, tomato and potato, respectively. Immature mortality were 12.9, 18.1 and 12.3% at the same three host plants. Females of B. tabaci oviposited means of 51.8, 60.1 and 67.5 eggs on aubergine, tomato and potato, respectively and had a mean longevity of 8, 14 and 12.9 days on the same three host plants. The net reproductive rate was 18.12, 15.06 and 27.63 and the daily intrinsic rate of increase was 0.141, 0.092 and 0.165 on aubergine, tomato and potato, respectively.
