| 中文摘要: |
| 黄芪根瘤象Sitona simillimus Korotyaev(我国于2013年首次报道该虫时误鉴为Sitona ophtalmicus Desbrochers)为我国近年在黄芪上新发现的一种优势害虫,在我国黄芪主产区的甘肃陇西、岷县、临洮等地均有分布,以成虫、幼虫为害黄芪的根、叶,严重影响黄芪的产量与品质。本文概述了黄芪根瘤象的研究概况,对其各虫态的形态特征进行了描述,并提供了成虫、幼虫、卵、蛹及雌雄生殖器的特征彩图,为该虫的正确鉴定提供资料。 |
| 英文摘要: |
| Sitona simillimus Korotyaev, misidentified as Sitona ophtalmicus Desbrochers first reported in China in 2013, was found as a dominant pest of Astragalus membranaceus. It was distributed in the main producing area of A.membranaceus in Gansu province. The adults and larvae feed on roots and leaves, which seriously affects the yield and quality of A.membranaceus. This paper summarizes the research summary of S.simillimus, describes the morphological characteristics of each stage of the pest, and provides color pictures of the adults, larvae, eggs and pupa (including male and female genitalia). |
