散白蚁对灭蚁粉剂的传毒能力研究

The capacity study of toxicant transmitting for Reticulitermes aculabialis

目的了解散白蚁对氟虫胺、吡虫啉和灭蚁灵的传毒能力。方法测定粉剂的触杀作用的传递效应。结果白蚁对50%的灭蚁灵粉剂均有一、二级传毒能力,对25%的灭蚁灵均有一级传毒能力;白蚁对0.1%的氟虫胺均有一级传毒能力,对0.01%的氟虫胺基本上无一级传毒能力;白蚁对1%的吡虫啉均有一级传毒能力,0.25%的吡虫啉基本上无一级传毒能力。结论白蚁对灭蚁灵的传毒能力最大,其次是氟虫胺,最小的是吡虫啉。

Objective To study the termite＇s capacity of transmitting toxicity of mirex, sulfluramid and imidaclorprid. Methods Determining the transfer capacity of contact actions of termiticides. Results Reticulitermes aculabialis had first and second toxicant transmitting ability to 50% mirex powder, to 25% mirex powder＇s treatment, all had first toxicant transmitting ability. The termite had first toxicant transmitting ability to three 0. 1% sulfluramid powder＇s treatments and hardly had first transmitting ability to 0. 01% sulfluramid powder＇s treatments. To 1% imidaclorprid powder, the termite had first toxicant transmitting ability, but nearly not to 0. 25% imidaclorprid powder, Conclusion The laboratory results indicated that in three termiticides, the termite had the most capacity of transmitting toxicity in mirex, next was in sulfluramid and the third was in imidaclorprid.
