The toxicities of butene-fipronil to Drosophila melanogaster were evaluated, in comparison to nine conventional insecticides. According to the mean LD50 values of the larvae from CS, w (1118) and Oregan strains, butene-fipronil, abamectin, spinosad and chlorpyrifos exhibited high levels of toxicity. Imidacloprid, alpha-cypermethrin and clothianidin showed middle levels of toxicity. And acephate, methomyl and acetamiprid had low levels of toxicity. To the adults, butene-fipronil, alpha-cypermethrin, spinosad, and chlorpyrifos were relatively more toxic, whereas acephate, methomyl, acetamiprid, imidacloprid, clothianidin and abamectin were relatively less toxic. Butene-fipronil and abamectin were more toxic to larvae. In contrast, spinosad, alpha-cypermethrin, and clothianidin were more toxic to adults. Moreover, the toxic risk assessment using a risk quotient value revealed that butene-fipronil was safe to D. melanogaster adults. Thus, our results suggested that butene-fipronil is harmful to D. melanogaster larvae, but it is relatively safe to the adults.
