Baseline susceptibility of Bemisia tabaci to a new anthranilic diamide insecticide, cyantraniliprole 10 OD

摘要

Whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), is one of the most important sucking insect pests, and has more than 600 host plants worldwide, including vegetables crops like tomato, okra, chilli, legumes, eggplant and cucurbits. It not only causes direct damage by feeding on host plant but as a vector it spreads many viral diseases of economic importance in many agricultural and horticultural crops (Jesus Navas Castillo et al., 2011). B. tabaci is considered as a complex cryptic species and was recently split into at least 31 morphologically indistinguishable species, some of them are world's most damaging pests of agriculture (De Barro et al., 2011). At present, chemical control of whitefly mainly relies on extensive use of conventional and neonicotinoid insecticides by way of foliar sprays, seed treatment and soil application. But extensive use of these insecticides has led to development of insecticide resistance in B. tabaci to all major groups like organophosphates, carbamates, synthetic pyrethroids and neonicotinoids that have been used for its management in last few decades (Horowitz et al., 2005 and Kodandaram et al., 2014). Hence, there is need and great demand for new insecticide molecules with unique mode of action andtarget sites, which are an essential component of a pest and resistance management program for whitefly.
