摘要
为了探讨氟虫胺、吡虫啉、阿维菌素、毒死蜱4种药剂对红火蚁野外的毒杀效果。采用毒饵法对试验区内的红火蚁蚁巢进行处理。结果表明:0.5%氟虫胺饵剂和2.0%吡虫啉饵剂对红火蚁蚁巢的防控效果最好,校正减退率分别可达81.16%、79.17%。其次是0.8%氟虫胺饵剂,校正减退率最高可达76.79%。阿维菌素也表现出较好的灭杀效果,校正减退率达63.16%;而1.0%吡虫啉及0.4%毒死蜱微胶囊饵剂对红火蚁的效果最差。通过试验得出:0.5%氟虫胺和2.0%吡虫啉对红火蚁蚁巢的防控效果最好,为研制防治红火蚁的有效药剂之一。
To explore the control effect of four baits such as Sulfluramid, Imidacloprid, Avermectins and Chlorpyrifos on Solenopsis invicta. Four kinds of poisonous baits, Sulfluramid, Imidacloprid, Avermectins and Chlorpyrifos, were used to kill Red imported fire ant nests outdoors. The results showed that the efficiency of 0.5% Sulfluramid and 2.0% Imidacloprid were the best, and their decrease rates were 81.16% and 79.17%, respectively. And 0.8% Sulfluramid took the second place, with the decrease rate of 76.79%. Avermectins also had a good killing effect, and its decrease rate reached 63.16%. Yet, 1.0% Imidacloprid and 0.4% Chlorpyrifos were the least effective. 0.5% Sulfluramid and 2.0% Imidacloprid had the best effects on Solenopsis invicta. So, they were the materials to prevent and control Solenopsis invicta.
