The infection behavior of Steinernema carpocapsae infective juveniles (IJ) was investigated in the presence and absence of S. glaseri. Mixed inoculation of S. carpocapsae with S. glaseri IJ significantly raised the nictation rates of S. carpocapsae IJ. Significantly more S. carpocapsae IJ migrated to the host insect in the mixed inoculation with S. glaseri IJ on agar plates. More S. carpocapsae IJ penetrated into the host insect placed 2 cm below the surface in the mixed inoculation with S. glaseri IJ. More S. glaseri than S. carpocapsae IJ penetrated into hosts placed 7 cm deep. Irrespective of host location, the male ratio of S. carpocapsae IJ established in the host body was always higher in the mixed inoculation with S. glaseri IJ.
在有和没有格氏斯氏线虫（Steinernema glaseri）的情况下，研究了小卷蛾斯氏线虫（Steinernema carpocapsae）感染性幼虫（IJ）的感染行为。小卷蛾斯氏线虫感染性幼虫与格氏斯氏线虫感染性幼虫混合接种显著提高了小卷蛾斯氏线虫感染性幼虫的nictation率。在琼脂平板上，与格氏斯氏线虫感染性幼虫混合接种时，显著更多的小卷蛾斯氏线虫感染性幼虫迁移到宿主昆虫身上。在与格氏斯氏线虫感染性幼虫混合接种时，更多的小卷蛾斯氏线虫感染性幼虫穿透到位于表面以下2厘米处的宿主昆虫体内。穿透到7厘米深处宿主中的格氏斯氏线虫比小卷蛾斯氏线虫感染性幼虫更多。无论宿主位置如何，在与格氏斯氏线虫感染性幼虫混合接种时，在宿主体内建立的小卷蛾斯氏线虫感染性幼虫的雄性比例总是更高。
