Abstract: Objective To determine the contact toxicity of cyfluthrin on the workers of Coptotermes formosanus.Methods The workers of C.formosanus were contacted with the filter paper or sandy soil treated with cyfluthrin and their mortality was evaluated every 24 hours.Results Toxicity of cyfluthrin on the workers of C.formosanus was related with the time of treatment and the concentration of treatment.The mortality of workers continuously exposed to the filter paper treated by 25 mg/L cyfluthrin solution was 100% at 8 days after treatment,and the mortality of workers exposed 30 minutes to the filter paper treated by 800 mg/L cyfluthrin solution was 100% at 3 days after treatment.However,if the workers of C.formosanus were contacted with sandy soil treated with 20 mg/L cyfluthrin solution,the mortality would reach 100% at 6 days after exposure.Conclusion 5.7% cyfluthrin EC could be used for termite control.
摘要: 目的 测定氟氯氰菊酯乳油对台湾乳白蚁的触杀毒性。方法 让供试白蚁与浸药滤纸和含药沙土接触,定时观测试虫的死亡率。结果 氟氯氰菊酯对台湾乳白蚁的毒性与处理时间和处理浓度有关。连续处理时,与25 mg/L药液处理滤纸接触的台湾乳白蚁,8 d后的死亡率为100%;与浸药滤纸只接触30 min,3 d后台湾乳白蚁100%死亡所需的药液浓度为800 mg/L。土壤处理时,若药液浓度达到20 mg/L,6 d后供试白蚁会全部死亡。结论 5.7%氟氯氰菊酯乳油在生产上可用于防治台湾乳白蚁。
