摘　　要：本文报告叶氏腹腔丝虫与唇乳突腹腔丝虫各期幼虫的形态鉴别特征,两者感染期幼虫头端均有两圈小乳突,前者每圈为4个,后者内圈为6个、外圈4个;叶氏腹腔丝虫感染期幼虫尾端钝圆,末端有6个小乳突呈弧行分布,唇乳突腹腔丝虫尾端呈指状,末端有3个乳突成一横排。黎氏腹腔丝虫与马腹腔丝虫的感染期幼虫头端均有两圈小乳突,每圈为4个,前者尾端基部窄,延伸如柳叶状,3个乳突均呈球形;后者尾端圆锥状,末端1个乳突球形,亚末端2乳突仅稍突出于体壁。上述4种腹腔丝虫肛比率均小于3。首次描述我国匐行恶丝虫各期幼虫的形态,感染期幼虫3个尾端乳突呈球形,互相靠近,肛比率小于2。This is the first report on the morphology of the larva stages Of Setaria erschovi and S. labiato papillosa. The infective larvae of S. erschovi have 2 circles of 4 small papillae in the anterior end, while those of S. labiato papillosa have an inner circle of 6, and an outer circle of 4 papillae. The posterior terminal of S. erschovi is bluntly round with an are of 6 small papillae, and that of S. labiato papillosa is digit-like with a row of 3 papillosa. Different from the above 2 species, there are 2 circles of 4 small papillae on the anterior end of the infective larvae of S. leichu-ngwingi and S. equina. The posterior end of S. leichungivingi is willow-like with 3 ball-shaped papillae, and that of S. equina is conical with 1 pap-illa on the tip and 2 slightly protrusive on the sub-tip. Anal ratio of the above mentioned 4 species is less than 3. For the first time in China, the morphology of different larva stages of Dirofilaria repens is described. There are 3 closely located spherical caudal papillae in the infective larvae, and the anal ratio is less than 2.
