中文摘要:为探索高海拔地区生物防治的新途径，筛选可持续防控门源草原毛虫Gynaephora menyuanensis（Chou et Yan）的天敌资源，在 3 473 m 海拔条件下系统评估捕食性天敌蠋蝽 Arma custos（Fabricius）成虫对该虫低龄幼虫的捕食特征与持续控害能力。结果显示：蠋蝽成虫对门源草原毛虫2龄和3龄幼虫的捕食行为均符合Holling II型功能反应模型。蠋蝽雄成虫对门源草原毛虫2龄幼虫的瞬时攻击率最高，为5.050，对3龄幼虫的处理时间最短，为0.247，对2龄幼虫的捕食效率最高，为17.782。连续14 d的捕食试验结果表明，蠋蝽成虫在长期捕食过程中仍维持较高的捕食活性与存活水平，总捕食量达到25.8~37.2头，雌、雄成虫存活率分别在60%和70%以上。综上，蠋蝽在高寒草原生态系统中对门源草原毛虫低龄幼虫表现出较强的捕食能力，表明其在高海拔地区具备成为生物防治天敌的应用潜力。

Abstract:To explore effective biological control strategies for high-altitude regions and to identify sustainable natural enemy resources for managing tussock moth Gynaephora menyuanensis, the predation characteristics and sustained control capacity of the predatory bug Arma custos adults against earlyinstar larvae were systematically evaluated at an altitude of 3 473 m. The results showed that predation by A. custos adults on 2nd- and 3rd-instar larvae of G. menyuanensis conformed to the Holling type II functional response model. Male adults exhibited the highest instantaneous attack rate (5.050) against 2nd-instar larvae, the shortest handling time (0.247) when preying on 3rd-instar larvae, and the highest predation efficiency (17.782) against 2nd-instar larvae. Results from a 14-day continuous predation experiment indicated that A. custos adults maintained high predatory activity and survival during prolonged feeding, with a cumulative predation of 25.8-37.2 larvae and survival rates exceeding 60%-70% for females and males. Overall, A. custos exhibits strong predatory capacity against early-instar larvae of G. menyuanensis in alpine grassland ecosystem, highlighting its promise as a biological control agent in high-altitude regions.
