目的研究0.25%氟虫腈.氟铃脲的复配剂对苏州乳白蚁的毒力传递能力。方法在实验室内进行毒力传递试验。结果氟虫腈:氟铃脲=1∶50时,50和100 mg/L浓度下对苏州乳白蚁的胃毒毒力传递有效次数可达到3次;0.25%氟虫腈.氟铃脲粉剂对苏州乳白蚁的接触毒力传递有效次数可达到2次。结论 0.25%氟虫腈.氟铃脲的复配剂在室内试验中对苏州乳白蚁具有较强的毒力传递能力,能够有效的防治苏州乳白蚁。
Objective To study the virulent transmission ability of 0.25% fipronil and hexaflumuron to S. termitis. Methods Toxicity test was conducted in the laboratory. Results Fipronil: hexaflumuron = 1: 50, the effective doses of gastric and virulent transmission to S. terriana at 50 and 100 mg / L were up to 3 times, and that of fipronil 0.25% Suzhou termites contact toxicity transmission effective number of times up to 2 times. Conclusion 0.25% fipronil and hexaflumuron compound have strong virulence ability in laboratory test, which can effectively prevent and control suzhou termites.
