ABSTRACT
Studies were conducted to compare host preference, fecundity and longevity of Bemisia tabaci on brinjal and tomato. Results revealed that the highest number of eggs (76.41), nymph (14.5) and adult (9) of whitefly were on brinjal than tomatoes and found it suitable for feeding and oviposition. Significantly more B. tabaci adult females (81.32) were found feeding on brinjal than tomato (27.50). The longevity of developmental stages of B. tabaci was slightly higher on brinjal than tomato while the longevity of 2nd and 3rd instar nymphs was higher on tomato than brinjal. Females laid an average of 142.60 ± 3.01 eggs over their lifetime on brinjal and 98.41 ± 1.96 eggs on tomato.
Keywords: Bemisia tabaci, brinjal, fecundity, host preference, tomato.
