摘　　要：近20年以来,国外一些研究发现斯氏科(Steinernematidae)和异小杆科(Heterorhabditidae)的昆虫病原线虫作为生物防治制剂不仅能够主动寻找寄主、侵染有害昆虫,而且还能有效地抑制植物线虫。本课题组研究发现小杆科、小杆属Rhabditis(Oscheius)的某些昆虫寄生线虫也有抑制植物线虫的作用。关于这些研究国内报道甚少。为便于同行及相关学者的研究和资料查询,本文综述了昆虫线虫对植物线虫的抑制作用和影响因素,并对研究的意义进行了讨论,以供参考。Some research reports from foreign countries showed that EPNs from the families of Steinernematidae and Heterorhabditidae as biological control agents are not only searching host actively, infecting insect pests effectively, but also suppressing PPNs efficaciously. In the study we found that some nematode isolations from Rhabditis （Oscheius） have also the effect of suppression on PPNs. There is few reports related to this field. For the convenience of research and information citation to Chinese nematologists and other related scientists, the insectivorous nematodes suppression to PPNs, the influence factors to the suppression and the significance for the research were reviewed in this report, as reference.
