摘　　要：目的　证明河北、河南、安徽三省冈田氏绕眼果蝇对结膜吸吮线虫是否一样具易感性。方法　于 1998年～ 1999年先后对河北、河南及安徽省进行了犬感染结膜吸吮线虫调查 ,同时捕获冈田氏绕眼果蝇并分别繁殖出第二代蝇 ,以安徽的结膜吸吮线虫初产蚴进行喂饲感染 ,观察三省果蝇对该虫的易感性。结果　三省的第二代果蝇在感染后 ,于 2 2天 ,2 1天和 2 3天检查 ,河北省的 4 5只 ,阳性 2只 ,占 4 4 4 % ;河南省的 5 3只 ,阳性 3只 ,占 5 6 6 % ;安徽省的 76只 ,阳性 3只占 3 94 %。三省果蝇感染的组间差别 ,经统计学处理 (χ2 =0 19,P >0 0 5 ) ,无显著性差异。结论　证明了河北、河南。Aim To confirm Amiota okadai as the intermediate host of Thelazia callipaeda in other parts of China as well as in Anhui province Method From 1998 to 1999,we investigated dogs infected in Hebei,Henan,and rural area of Anhui respectively and A okadai were captured The newborn larvae of T callipaeda from Hefei suburb were fed to the second generation of A okadai from three provinces and the susceptibility to A okadai was observed Result A okadai from three provinces on day 22,21,and 23 after infection were examined 2 positive in 45(4 44%)from Hebei,3 positive in 53(5 66%)from Henan,and 3 positive in 76(3 94)from Anhui were found No statistically significant difference(χ 2=0 19,P>0 05)was noted among A okadai infected with T callipaeda from 3 provinces Conclusion A okadai from 3 areas have similar susceptibility to T callipaeda and are the intermediate host of T callipaeda in China
