摘要: 目的 了解伊维菌素对台湾乳白蚁(Coptotermes formosanus)和黄胸散白蚁(Reticulitermes flaviceps)的毒杀效果,寻求对环境友好的杀白蚁药剂。方法 采用毒沙接触法和木块浸药饲喂法,在室内测定伊维菌素对台湾乳白蚁和黄胸散白蚁的毒效。结果 100mg/L浓度毒沙接触处理24h,2种白蚁的死亡率均达到100%;浸药木块对2种白蚁的毒力效果具有明显的时间效应,低浓度处理药效差异不显著,25mg/L浓度处理即显示出一定的毒杀效果。结论 伊维菌素对台湾乳白蚁和黄胸散白蚁具有良好的毒杀作用,在防治白蚁方面具有较大的开发潜能。

Abstract: Objective In order to explore the sound environmentally chemicals for termite control,the toxic effects of ivermectin against the workers of Coptotermes formosanus and Reticulitermes flaviceps were determined. Methods To let the worker termites contact with the ivermectintreated sands or feed the wood block treated by ivermectin solution. Results All of the worker termites of C.formosanus and R.flaviceps tested would died within 24 hours after treatment when they contacted with sands treated by 100 mg/L ivermectin solution. When the workers of C.formosanus and R.flaviceps were fed with the wood blocks treated by different concentrations of ivermectin solution,the mortality of termites tested increased as the time of treatment. When the concentration of ivermectin solution for the treatment of wood block was higher than 25 mg/L,most of termites fed on the wood blocks would died. Conclusion The ivermectin has good toxic effects on the workers of C.formosanus and R.flaviceps. It is suggested that ivermectin has good future in termite control
