| 中文摘要: |
| 河曲丝叶蜂 Nematus hequensis Xiao 近年来成为北京柳树上的一种重要害虫。在检查了河曲丝叶蜂的模式标本后，发现对于雄虫的后足颜色描述有误。本文描述了各虫态的形态特征（附有彩色生态图和雌性锯腹片特征图）、调查了相关生物学特性，并提出了防治策略，重点在于树干上设置粘性胶环防治上下树的大龄幼虫和人工防治地下树干周围的茧。 |
| 英文摘要: |
| The willow sawfly Nematus hequensis Xiao is an important pest on willows recently in Beijing. The original description for color of male legs is not correct after examination of the type specimens. The present paper described its morphological characteristics of adult, egg, larva and pupa, provided with color pictures (including image of female lancet). It also includes the bionomic habits related to control. The control strategies should put emphasis on application of sticky traps for the old instar or matured larvae climbing down the tree and artificial control measures for the eonymphs and pupae in soil near the willow tree base. |
