摘要: 1994~1998年,在塔城和哈密麦双尾蚜Diuraphis noxia (Mordvilko) 分布区的调查结果显示:小麦收获后,野燕麦、黑麦和自生麦苗是麦双尾蚜的重要替代寄主,偃麦草和羊草上有少量的麦双尾蚜发生,其它禾本科杂草上很少发生麦双尾蚜。在塔城冬、春麦混合种植区,冬麦田是麦双尾蚜的主要越冬点。从5月份开始有翅蚜不断迁移到春麦上为害,秋季主要从晚熟春麦迁移到冬麦上产卵越冬。

关键词: 麦双尾蚜, 替代寄主, 季节转移

Abstract: Several species of grasses were regularly surveyed for the existence of the Russian wheat aphid,Diuraphis noxia (Mordvilko),during 1994~1998 in Tacheng and Hami,Xinjiang Uygur Autonomous Region. Avena fatua,Secale cereale,Elytrigia repens and volunteering wheat served as the important alternate hosts for the aphid after crop harvest. In Tacheng,early-sown winter wheat provided for RWA an overwintering refuge from where the aphids transferred to spring wheat or the alternate hosts in spring,and came back in fall.

Key words: Diuraphis noxia (Mordvilko), alternate hosts, seasonal transfer
