氟虫胺毒饵对台湾乳白蚁的毒性和引诱性研究

目的测定氟虫胺毒饵对台湾乳白蚁的毒性及引诱性。方法采用滤纸法测定氟虫胺毒饵对白蚁的毒性,用琼脂打孔的方法测定氟虫胺毒饵对白蚁的引诱性。结果0.05%和0.08%氟虫胺毒饵对台湾乳白蚁具有良好的毒杀效果,二者致死全部供试白蚁的时间均为5 d;0.05%和0.08%氟虫胺毒饵对台湾乳白蚁均有良好的引诱效果,其引诱白蚁的比率比对照均达74%以上。结论实际配制毒饵采用0.05%氟虫胺浓度即可起到较好的白蚁防治效果。

Toxic effects and attractive action of sulfluramid baits against Coptotermes formosanus

Objective To determine the toxic effects and attractive actions of sulfluramid baits on the workers of Coptotermes formosanus. Methods The toxic effects of sulfluramid baits on the workers of C.formosanus were tested by the method of filter paper-dipping chemical solution,and the attractive action were tested using agar as the barrier.Results 0.05% and 0.08% sulfluramid baits had high toxicities on the workers of C.formosanus and the workers tested reached 100% mortalities within 5 days after treatment.0.05% and 0.08% sulfluramid baits had good attractive action on the workers of C.formosanus and the rates of workers visiting two baits were at least 74% higher than that visiting the control baits. Conclusion It was recommended to use 0.05% sulfluramid bait for termite control in the field.
