自从Stuckey(1917)在我国发现人体结膜吸吮线虫(Tkelazia callipaeda)病例以来,对本虫的中间宿主问题一直是寄生虫学科中人们关注的一个问题,并为此进行了大量的实验探讨。Faust(1928)曾以蟑螂(Blatella germanica)作过感染实验,未获成功,Roa(1949)和光化县人民医院等(1976)曾在家蝇体内检获线虫幼虫,并就此认为是结摸吸吮线虫的幼虫。我们自1982年以来对本虫中间宿主的调查研究中,先后检查家蝇22328只,感染线虫丝状蚴的蝇为147 Since Stuckey (1917) discovered the human case of Tkelazia callipaeda in our country, the intermediate host problem of this insect has always been a concern in the parasitology discipline and a great deal of experimental research has been done for this purpose. Faust (1928), who had previously been infected with Blatella germanica, was unsuccessful. Roa (1949) and the People’s Hospital of Guanghua County (1976) seized nematode larvae in houseflies and, in this regard, considered to be infected with nematodes larva. In our survey of intermediate hosts of this insect since 1982, we examined 22,318 houseflies and flies infected with nematode filamentous larvae at 147
