摘　　要：昆虫病原线虫Ｓｔｅｉｎｅｒｎａｍａｃａｒｐｏｃａｐｓａｅ种的Ａ２４品系对４种常用杀虫剂的抗药性测定表明，该线虫对氧化乐果、灭杀毙、辛硫磷均有较强的抗性，而甲基异柳磷对该线虫有较大的毒性。室内试验表明，该线虫分别与氧化乐果及灭杀毙混用对蛴螬（ＨｏｌｏｔｒｉｃｈｉａｄｉｏｍｐｈａｌｉａＢｔｅｓ）的毒杀均有明显的增效作用，它与氧化乐果混用的共毒系数略高于与灭杀毙混用。A study on the effect of S.carpocapsae mixed with some insecticides on grub H.diomphalia was carried out under laboratory experiment.The result showed that Stainernema carpocapsae strain A24 was resistant to omethoate,phoxim,mieshabi and both of CTC(co-toxicity coefficient) from the nematode mixed with omethoate and mieshabi were higher than 100.
