摘　　要：研究了不同浓度的斯氏线虫S.carpocapsae BJ对森林革蜱饱血雌蜱产卵量的影响。用浓度为1000、3000、5 000、7 000、10000IJs/dish的线虫接种到培养皿中侵染森林革蜱饱血雌蜱,对照组用重蒸水代替。结果表明,随着线虫浓度的增加,雌蜱的死亡率不断提高（30%-95%）;处理组饱血雌蜱的产卵量显著少于对照组,低浓度时随着线虫浓度的增加,产卵量呈显著下降的趋势,而浓度5 000IJs/dish以上的3个处理组之间,雌蜱的产卵量无显著差异;低浓度时线虫浓度的增加使线虫侵入率显著提高,浓度达到一定数值后,浓度的增加对线虫的侵入率和雌蜱的产卵量都无显著影响。This research aims to analyze the effect of Steinernema carpocapsae BJ with different concentrations on fecundity of full blood female Dermacentor silvarum.S.carpocapsae BJ with inoculated concentra tions of 1 000,3 000,5 000,7 000 and 10 000 IJs/dish were inoculated on the culture dishes to infect the full blood female D.silvarum and the redistillation water was instead of S.carpocapsae BJ in CK group.Along with the S.carpocapsae BJ concentration increasing,the mortality of female ticks was unceasingly enhanced （30% -95% ）. Compared with CK group,the fecundity of the full blood female D, silvarum was significantly less, Along with the S. carpocapsae BJ concentration increasing, the fecundity showed remarkably decreasing tendency when the concentration was low, The fecundity difference was not significant among the 3 treatments with the concentration of over 5 000 Us/dish. When the concentration was low, the increase of S, carpocapsae BJ concentration caused remarkable enhancement of its infection rate, When it reached certain concentration,the increase of S. carpocapsae BJ concentration had no significant effects on its infection rate and the fecundity of the female D, silvarum.
