摘要/Abstract

摘要： 昆虫病原线虫与体内细菌共生，专性寄生在昆虫体内，在害虫生物防治中发挥着重要作用。昆虫病原线虫致病性研究是其高效应用的基础，涉及线虫及其共生细菌对昆虫的交互作用。本文针对斯氏属和异小杆属线虫的致病因子及这类线虫与寄主昆虫互作机制进行了综述，为昆虫病原线虫的致病机制研究和应用提供参考。

Abstract: Entomopathogenic nematodes (EPN) are symbiotic with bacteria and play a vital role as biological control agents against pests.The research of pathogenicity of EPN is fundamental for the efficient application of EPN,involving the interaction between nematodes and their symbiotic bacteria on insects.In this paper,we reviewed the pathogenic factors of the EPNs of Steinernema spp.and Heterorhabditis spp.and the interaction mechanism between nematodes and host insects.The review would provide reference for further theoretical research and application of EPN.

Key words: entomopathogenic nematodes, pathogenicity, secreted protein, immunosuppression
