| 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。

| 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. |
