Tests with colonies of Culex pipiens fatigans from six localities in Kenya and Tanzania revealed high levels (60-90%) of susceptibility to infection with Wuchereria bancrofti. Twenty-six of 30 possible crosses between these colonies were performed and revealed no cases of incompatibility. All but 2 crosses produced near-normal sex ratios of F(1) adults, with a slight excess of females in 16 of 20 detailed assessments. The implications of these results for control work and filariasis transmission are discussed. From other data it is concluded that the strain of C. p. fatigans present in Kenya and Tanzania is homologous with populations found elsewhere in Africa and in southern Asia.
对来自肯尼亚和坦桑尼亚六个地区的致倦库蚊群体进行的测试显示，其对班氏吴策线虫感染的易感性水平很高（60%-90%）。在这些群体之间进行了30次可能杂交中的26次，未发现不相容的情况。除2次杂交外，所有杂交产生的F(1)代成虫的性别比例接近正常，在20次详细评估中有16次雌性略多。讨论了这些结果对防治工作和丝虫病传播的意义。从其他数据得出结论，肯尼亚和坦桑尼亚存在的致倦库蚊菌株与在非洲其他地区和亚洲南部发现的群体同源。
