Abstract

Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is a super pest that seriously endangers the development of the agricultural economy worldwide. To prevent and control B. tabaci, insecticides have been used for many years, which has inevitably led to increased tolerance to chemical agents. To elucidate the development of field resistance and more scientifically and efficiently control B. tabaci, in December 2024, we conducted bioassays on B. tabaci on soybeans in Suzhou, Anhui Province, using 14 insecticides. These fourteen insecticides, namely, abamectin, spinetoram, thiamethoxam, flupyradifurone, imidacloprid, dinotefuran, acetamiprid, thiacloprid, nitenpyram, bifenthrin, deltamethrin, pyridaben, flonicamid, and emamectin benzoate, have multiple action sites and have all shown good control effects on B. tabaci . The results revealed that B. tabaci has developed high resistance to many insecticides and that some insecticides have even tended to fail, but B. tabaci is still sensitive to a small number of insecticides. Different biotypes of B. tabaci differ significantly in terms of insecticide resistance. We determined that the population of B. tabaci on soybean in Suzhou was the MED (Q) biotype. It carried the TYLCV virus, with a virus carrying rate of 60%, but did not carry ToCV or CCYV.
