Performance of Bemisia tabaci (Hemiptera: Aleyrodidae) on healthy and Cotton leaf curl virus infected cotton
Florida Entomologist 91 (2), 249-255
Abstract: Cotton leaf curl virus (CLCuV) is a group of whitefly-transmitted Geminiviruses that cause extensive damage to cotton in India and Pakistan. Begomoviruses have a complex association with their whitefly vector. To further understand these relationships, fecundity and life history parameters of Bemisia tabaci (Gennadius) were compared on 5, 20, 35 d post inoculated (DPI), CLCuV infected and healthy cotton plants to determine the effect of virus on its vector. Cotton leaf curl virus infection increased percent egg viability of B. tabaci. Whiteflies deposited significantly fewer eggs on virus infected plants compared to healthy plants. The development time of whiteflies from egg to adulthood was significantly reduced on CLCuV infected plants with shorter nymphal and pupal duration. Male and female whiteflies had shorter longevity on CLCuV infected plants compared with healthy plants. The egg duration was similar on CLCuV infected and healthy plants regardless of DPI of plants.
