我区主要的地下害虫有蝼蛄、金针虫、金龟子(幼虫是蛴螬)等。这些害虫之间并不难识别,但是每种害虫中又有许多不同种类,例如蝼蛄分华北蝼蛄和非洲蝼蛄;金针虫分沟金针虫和细胸金针虫;金龟子有大黑金龟子、黄褐色金龟子、黑绒金龟子、无翅黑金龟子、阔胸金龟子等。它们的形态不同,习性和防治方法也不完全一样,所以下面介绍一下这几种害虫的形态特征,以便于对它们进行鉴别分类,做到及时防治,促进农业丰收。
The main underground pests in our area are 蝼 蛄, golden needle insects, chafers (larvae 蛴 螬) and so on. These pests are not hard to discern, but there are many different species in each pest, such as 蝼 蛄 in North 蝼 蛄 and African 蝼 蛄; Gingerworms ditches and fine-lipped insects; chafers have big black chafer, brown chafer , Black velvet beetle, wingless black beetle, wide chest beetle and so on. Their morphology, habits and control methods are not exactly the same, so the following describes the morphological characteristics of these pests in order to facilitate their classification, timely prevention and control to promote agricultural harvest.
