本文用南京株和合肥株淡色库蚊以及广东株致倦库蚊分别人工感染广东株周期型班氏丝虫，并对其易感性进行比较。用一名微丝蚴密度为２４条／６０μｌ的班氏丝虫微丝蚴血症者血液感染南京株淡色库蚊３３４只，合肥株淡色库蚊１３９只和致倦库蚊２４１只，Ｌ３阳性率分别为１２．５７％、５．７６％和５．８０％。结果表明上述三株库蚊均对广东株班氏丝虫易感，以南京株淡色库蚊的易感性为最高，合肥株淡色库蚊与致倦库蚊的易感性处于同一水平上，这提示在丝虫病的防治后期和监测工作中应加强对来自原疫区的外来人口的监测，及时发现和消除输入性传染源，以巩固丝虫病防治成果。
In this paper, Nanjing strains and Hefei strains of Culex pipiens pallens and Culex pipiens pallens strains of Guangdong were artificially infected with Guangdong strains of periodic line Bancroftian filarial, and its susceptibility were compared. A blood bank of microflora of Bancroftian filariasis with a microfilament density of 24/60 μl was used to infect 334 Culex pipiens pallens from Nanjing, 139 Culex pipiens pallens from Hefei and 241 Culex pipiens quinquefasciatus, with positive L3 Rates were 12.57%, 5.76% and 5.80% respectively. The results showed that the above three Culex pipiens were susceptible to Guangdong strain Wuchereria tenuis and the highest susceptibility to Culex pipiens pallens from Nanjing strain was the highest, while susceptibility to Culex pipiens pallens from Culex pipiens pallens was the same as that from Culex pipiens pallens In the later stage of prevention and treatment of filariasis and monitoring, the monitoring of migrants from the original endemic areas should be strengthened to detect and eliminate imported sources of infectious agents in time to consolidate the achievements of prevention and control of filariasis.
