摘　　要：麦茎蜂是干旱和半干旱地区小麦的一种主要害虫,以幼虫钻蛀小麦茎秆为害,使植株的光合作用减弱,产量减少,籽粒的蛋白质含量下降,发芽率和出苗率降低。麦茎蜂幼虫为害隐蔽,单一的措施很难及时有效地降低其种群数量,不同防治方法的综合应用,也即害虫综合治理,已成为治理麦茎蜂的主要策略。本文以灰翅麦茎蜂和北美麦茎蜂为主,综述了麦茎蜂的为害特点、寄主选择、田间分布、造成的损失及防治措施等研究进展,并初步探讨了今后麦茎蜂害虫防控的研究和应用方向,以期为进一步有效控制其危害提供参考。Wheat stem sawflies are major insect pests on wheat Triticum spp. in arid and semi-arid areas. Larvae injure wheat plants by chewing through their stems, and thus weaken photosynthesis process, leading to crop output reduction, drop of protein content in grains, and lower germination and emergence rate of seeds. Due to cryptic damage symptoms of larval wheat stem sawflies, any single measure has proven ineffective to reduce their populations. Applications of integrated pest management （IPM） have been becoming a dominant strategy for controlling these pests. Taking two species, Cephus fumipennis Eversmann and Cephus cinctus Norton as examples, the paper reviewed the pests＇ damage extent, host preference, field distribution, yield loss caused, and control measures, etc. Furthermore, we conducted preliminary discussions on future directions for global research activities and implementation of control strategies for managing wheat stem sawflies, so as to provide references for more efficient pest control.
