ES-生物烯丙菊酯与氯菊酯联合作用的研究

Joint action of ES-bioallethrin and permethrin

目的评价ES-生物烯丙菊酯与氯菊酯对淡色库蚊、家蝇的联合作用,为卫生杀虫剂的合理应用提供参考。方法分别采用圆桶喷雾法、玻璃瓶药膜法测试药剂对淡色库蚊、家蝇的击倒和致死性能,采用共毒系数法评价击倒的联合作用,采用增效效果法评价致死的联合作用。结果当ES-生物烯丙菊酯与氯菊酯的配比为3∶100~4∶100时,对蚊的击倒性能表现相加作用,5∶100~7∶100时表现增效作用;当3∶100~7∶100时对蝇的击倒性能均表现增效作用;3∶100~7∶100时对蚊蝇的致死性能均表现为相加作用。结论当选择ES-生物烯丙菊酯与氯菊酯复配时,宜选择5∶100~7∶100等具有增效作用的配比。

Objective To evaluate reasonable application of the joint action of ES-bioallethrin and permethrin.Methods The knocked or killed activity was tested by bucket-spray for Culex pipiens pallens and thin coating of glass bottle for Musca domestica.The joint knocked action was evaluated by cotoxicity coefficient and the joint killed action was evaluated by synergistic effect.Results For mosquito,the joint knocked actions were addition at 3∶ 100-4∶ 100 of ES-bioallethrin and permethrin,and synergy at 5∶ 100-7 ∶ 100.For housefly,the joint knocked actions were synergy at 3∶ 100-7∶ 100.For mosquito and housefly,all joint killed action was addition.Conclusion 5∶ 100-7∶ 100 is better proportion for the mixture of ES-bioallethrin and permethrin.
