摘　　要：用线虫浓度为8000 IJ/ml的斯氏线虫S.carpocapsae BJ品系侵染森林革蜱饱血雌蜱。实验期间统计饱血雌蜱的产卵量,用解剖镜观察线虫进入蜱体内的部位。结果表明,经线虫侵染后,平均每只蜱的产卵量为(327.0±11.0)个,而对照中每只蜱的产卵量为(4420.6±282.6)个;经线虫侵染后饱血雌蜱的死亡率高达90%。线虫的侵染使雌蜱的产卵量显著减少。线虫主要从蜱的口器、肛门、气门和生殖孔及节间膜处入侵。The flail blood female ticks of Demacentor silvarum were infected with Steinernema carpocapsae BJ concentration of 8000 IJ/ml, During the experiment, the statistics of fecundity of full blood female ticks and observation with anatomical lens on the part of ticks infected by the S. carpocapsae were done. The result showed that the average fecundity per tick was 327.04- 11.0,and the CK was 4 420.64-282,6 （x^-± s） after they were infected by S. carpocapsae,The mortality of full blood female ticks infected by carpocapsae was up to 90%.The fecundity of female ticks infected decreased significantly. The mouthparts, anus, spiracle, genital pore and inter-segmental membranes of ticks were main infected parts,
