The effects of eight neonicotinoid seed treatments against the cotton aphid Aphis gossypii and its natural enemies in Bt cotton fields were evaluated, and the concentrations of these neonicotinoids in cotton leaves and soil were also investigated. It has been known as that B. bassiana TBI-1 have a insecticidal effect on the twospotted spider mite (Teranychus urticae) and the greenhouse whitefly (Trialeurodes vaporariorum) these days. Acyrthosiphon. Multiple applications may be needed. treatment of the parental generation with CucB and EGCG, except F1 of CU on cotton after exposed to CucB (Table3). After treatment with biological insecticide, the mean of increasing rate of aphids was at around recorded at around 0.21 while at around 0.24 in non-treated TBI-1 biological insecticide condition during 1 week. Like most aphids, A. gossypii is an important virus vector: it can transfer about 70 different types, some of which may cause more damage than the aphid itself.
