| 中文摘要: |
| 黏虫和劳氏黏虫往往混合发生, 给小麦、玉米和水稻等造成严重的产量损失。本文从卵、幼虫、蛹和成虫4个虫态分别描述了这两种黏虫在形态特征上的差异。两种黏虫卵无差异。低龄幼虫中黏虫刚毛基部的毛片色深, 2龄幼虫前胸背板上各条背线较明显; 劳氏黏虫毛片色浅, 2龄幼虫各背线不明显。高龄幼虫中黏虫头部有“八字纹”, 气门近圆形, 气门筛黑色有光泽; 劳氏黏虫头部除“八字纹”外唇基还有一黑褐色斑, 气门椭圆形, 气门筛黄褐色。黏虫蛹腹部背面5~7节有刻点, 臀棘着生近于平行; 劳氏黏虫蛹4~7节有刻点, 臀棘呈“八”字形。黏虫成虫前翅有环纹、肾形纹, 劳氏黏虫则无。本研究旨为两种黏虫的田间调查提供技术支撑。 |
| 英文摘要: |
| Mythimna separata (Walker) and Mythimna loreyi (Duponchel), often take place together and cause serious yield losses on wheat, maize and rice. In this study, the morphological differences in egg, larval, pupal and adult stages of these two kinds of species were described, and corresponding color photographs were provided. This may provide technical instructions for field investigation. |
