摘要

Studies on biology of cotton whitefly, Bemisia tabaci were carried out under screen house conditions on cotton (variety H-1117 and hybrid RCH 134 BG II). Whitefly exhibited three nymphal instars and a pupal stage before reaching the adult stage. The fecundity varied from 34-49 and 45-69 eggs per female on cotton variety and cotton hybrid, respectively. Total life cycle from egg to adult was varied from 19-28 and 18-27 days on cotton variety and hybrid, respectively.
