摘　　要：红火蚁(Solenopsis invicta Buren)是危害极大的外来入侵害虫,对入侵地区的公共安全、农林产业和生态环境等方面构成严重威胁。本文在实验室条件下测定了不同饥饿程度和食物供给条件对红火蚁工蚁取食含0.05%茚虫威的大豆油后死亡率的影响。结果表明,非饥饿状态的工蚁(断食0 d)取食含茚虫威的大豆油后的校正死亡率显著低于饥饿状态的工蚁(断食3 d和10 d);提供人工凝胶食物的工蚁取食含茚虫威的大豆油后的校正死亡率显著低于提供对照空白凝胶的工蚁。本研究表明饥饿程度和食物供给条件可能影响毒饵法防治红火蚁,为科学合理使用毒饵诱杀该蚁提供理论依据。Red imported fire ant,Solenopsis invicta Buren,is a highly invasive pest,posing severe threats to public safety,agricultural and forestry industries,and ecological environments in invaded areas.The ef-fect of starvation status and food supply conditions on the mortality of S.invicta workers fed by soybean oil containing 0.05%indoxacarb was studied in laboratory.In general,the corrected mortality of non-starved S.invicta workers(starved for 0 d)was significantly lower than that of the starved S.invicta workers(starved for 3 or 10 d)when fed with soybean oil containing indoxacarb.Additionally,the corrected mortality of S.invicta workers provided with artificial gel food was significantly lower than that of S.invicta workers provided with control gel food after being fed with soybean oil containing indoxacarb.These results indicated that starvation status and availability of other food sources might influence the ef-fectiveness of the oil-based bait against S.invicta,providing insights into the fire ant control.
