氟虫胺毒饵对黄胸散白蚁的室内毒性和引诱性研究

目的测定氟虫胺毒饵对黄胸散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%氟虫胺毒饵对黄胸散白蚁具有良好的毒杀效果,二者致死全部供试白蚁的时间分别是13和9 d;0.05%和0.08%氟虫胺毒饵对黄胸散白蚁均有良好的引诱效果,其引诱率均高于85%。结论实际配制毒饵采用浓度为0.05%氟虫胺防治白蚁即可起到较好的防制效果。

Toxicity and attractive effect of sulfluramid baits on the workers of Reticulitermes flaviceps

Objective To test the toxicity and attractive actions of sulfluramid baits on the workers of Reticulitermes flaviceps.Methods The toxic effects of sulfluramid baits on the workers of R.flaviceps were tested by the method of filter paper-dipping chemical solution,and the attractive action of sulfluramid baits on the workers of R.flaviceps were tested using agar as the barrier.Results The 0.05% and 0.08% sulfluramid baits had high toxicities on the workers of R.flaviceps and 100% mortalities were at 13 days and 9 days after treatment respectively.The 0.05% and 0.08% sulfluramid baits had good attractive action on the workers of R.flaviceps and the rates of workers visiting these two baits were at least 20% higher than that of the control baits(pine wood).Conclusion It is recommended to use 0.05% sulfluramid bait for termite control in the field.
