|Publication abstract=Chemical control is important in the management of the tobacco whitefly, ''Bemisia tabaci'' (Gennadius) (Hemiptera: Aleyrodidae). Susceptibility of ''B. tabaci'' to insecticides may vary among different developmental stages and geographical populations. In this study, we examined toxicity of seven commonly-used insecticides to ''B. tabaci'' MED in four field populations from China. Avermectin has high level of toxicity to all stages of ''B. tabaci'' MED in all four populations. Cyantraniliprole and sulfoxaflor have high toxicity to adults. Spirotetramat, cyantraniliprole and flonicamid have high toxicity to nymphs but not adults. Acetamiprid, cyantraniliprole and sulfoxaflor have high toxicity to eggs. However, the relative toxicity of ''B. tabaci'' MED to these chemicals varied across different populations, with little consistency in population differences across developmental stages. Our findings together with some instances where LC<sub>95</sub> values were higher than field recommended dosages indicate field-evolved resistance to insecticides (such as thiamethoxam and sulfoxaflor) and stage-specific mechanisms that will influence effective control of ''B. tabaci'' MED by insecticides.
