摘要
目的 :掌握家蝇抗性动态变化 ,为控制抗性的发生与发展提供科学依据。方法 :微量点滴法。结果 :1995～ 1998年盐城市家蝇对敌敌畏、氯氰菊酯的抗性虽仍处在高抗水平 ,但总体上抗性呈下降趋势 ;对二氯苯醚菊酯的抗性处在中低抗水平 ,除射阳县外 ,均呈下降趋势 ;对溴氰菊酯的抗性均处于中低抗水平 ,且市区、建湖两个监测点呈逐年下降趋势 ,已接近敏感水平。结论 :根据家蝇抗性动态变化 ,及时采取综合防制、交替轮换或镶嵌用药等措施 。
Objective:To find out the dynamic of resistance in housefly and provide the scientific evidance to control the appearance and development. Method:The trace drop method was used. Results:The resistance to Dichlorovos and Cypermethrin was in high level from 1995 to 1998, but it did not develop and came to decline in the whole; The resistance to Phenothrin was modial or low level. All of them came to decline except Sheyang county; The resistance to Deltamethrin was lower in urban district of Yancheng city and Jianhu came to decline and to sensitive level. Conclusion:According to the appearance and development of the resistance the integrated prevention measures including reasonable drug used should be taken.
