【摘要】 本文在不同季节对采自北京 4个城区的家蝇Muscadomestica(L .)种群的乙酰胆碱酯酶 (AChE)对杀虫药剂的敏感度进行检测。结果发现 ,在 4个种群中 ,海淀区种群对敌敌畏、灭多威和残杀威 3种杀虫药剂不敏感的AChE的个体频率均为最低 ,且随季节变化不大 ;而西城、朝阳和丰台种群 ,对 3种杀虫剂不敏感的个体频率均有随季节呈上升趋势。但是这 3个种群上升的高峰期和上升的速度各不相同 ,其中丰台种群不敏感个体频率最高 ,其上升的速度也最快更多还原

【Abstract】 Sensitivity of AChE in housefly( Musca domestica )populations in Beijing were detected.The results showed that the insensitivity frequency of AChE was the lowest in Haidian population and the highest in Fengtai population.Except for Haidian population,the insensitive individual frequency in other three populations(Xicheng,Chaoyang,Fengtai)rose from Spring to Autumn.更多还原
