1976年莱西县原周格庄公社管道大队的大片麦田发生麦拟根蚜危害。该虫生活于小麦根际,为害根部,造成叶片由基部逐渐向上部枯黄,受害严重者不能抽穗,严重影响小麦产量。据调查在烟台地区部分县受害亦为严重。关于该虫国内尚无报导,为此我们对其形态特征。生物学特性进行了研究。麦拟根蚜属蚜科Aphididae绵蚜亚科Eriosomatinae根蚜族Fordini,ParacletusCimiciformis Hegden,在烟台地区属不全周期型。现先将其形态特征介绍如下,以供各地
In 1976 Laxi County, the original week grid commune pipe brigade tragedy occurred in wheat wheat aphid harm. The insects live in the wheat rhizosphere, root damage, causing the leaves gradually from the base to the upper part of the yellow, serious victims who can not heading, seriously affecting wheat yield. According to the survey, some counties in Yantai also suffered serious injuries. There is no report about this pest in our country, for which reason we have its morphological characteristics. Biological characteristics were studied. Aphididae Aphididae Aphididae Aphid subfamily Eriosomatinae root aphid family Fordini, ParacletusCimiciformis Hegden, in the Yantai region is not complete cycle type. Now its morphological characteristics are introduced below, for all over
