摘要： The increasing occurrence of resistance to chemical insecticides in insect pest populations is a serious threat to the integrity of current pest management strategies, and exploring new alternative chemistries is one important way to overcome this obstacle. Fluralaner, as a novel isoxazoline insecticide, has broad spectrum activity against a variety of insect pests, but little data is available about its effect on Lepidopterans. The effects of fluralaner on Spodoptera litura Fabricius, a widespread and polyphagous pest, were evaluated in the present study. Our results showed younger larvae were more susceptible to fluralaner treatment, but feeding and topical applications were similarly effective in 3rd instar larvae. Synergism assays indicated that piperonyl butoxide (PBO) could increase the toxicity of fluralaner to S. litura to a certain degree and P450 may be involved in the detoxification of fluralaner in vivo. Sublethal developmental effects included reduced larval body weight, decreased pupation and emergence, and notched wings in adults, accompanied by changes in the transcript levels of chitinase 5 (CHT5) and juvenile hormone acid methyltransferase (Jhamt), genes vital for insect development. Above results manifested that fluralaner is highly toxic to S. litura larvae via either topical or oral application and provide an indication of how this insecticide is metabolized in vivo. Further, our results provided a foundation for further development of fluralaner as a new tool in insect pest management.
