摘要: 麦双尾蚜Diuraphis noxia (Mordvilko)无翅孤雌蚜的体长、体宽、头宽、腹管宽、上尾片长、尾片长和触角节Ⅲ长等7个形态指标,在各龄期间差异显著。根据麦双尾蚜的翅、翅芽、触角节数、尾片形状、上尾片长与宽比值等特征作为龄期鉴别的主要指标,编制了麦双尾蚜龄期鉴定检索表。

Abstract: Under condition of 20~25℃, (80±10)% (RH) and 16∶8 (D∶L), the body length, body width, head width, siphunculus width, cauda length, supracauda length, antenna length, and third antennal segment length were significantly different among various instars and adult of the Russian wheat aphid. A key to different instars was given according to wing, wing bud, antennal segments, cauda shape, supracaudal morphs, and ratio of length to basal width of supracauda.

Key words: Russian wheat aphid (Diuraphis noxia (Mordvilko)), morphological features, key to instars and adult
