麦类负泥虫(Lema melanopus L,)属鞘翅目叶(虫甲)科,因其仅为害麦类作物,且幼虫背部负有泥状排泄物,故名。这是阿勒泰地区近年来新发生的害虫。为了有效地控制此虫,我们从1979年开始对其进行研究,现将初步结果报道如下。 一、危害情况 麦类负泥虫主要危害燕麦、大麦、冬小麦和春小麦,阿勒泰地区的布尔津县,吉木乃县均有发生。近几年来,麦类负泥虫发生蔓延很快,如1979年一八六团一连仅有小面积小麦受害,到1980年受害面积达1,016亩,1981年发展到3,000亩。麦类负泥虫的成虫和幼虫多在麦叶正面取食上表皮和叶肉,留下下表皮,故受害处常形成平行于叶脉的长条形白色透明薄膜,有时几个受害点 Lema melanopus L, a genus of Coleoptera, belongs to the genus Coleoptera, because it is the only plant that infects wheat, and the larva carries the mud-like excrement on its back. This is a new pest in the Altay region in recent years. In order to control this pest effectively, we started to study it from 1979, and the preliminary results are reported below. First, the damage Hazard Negative pests mainly harm oats, barley, winter wheat and spring wheat, Altay Prefecture Burqin County, Jimunai County have occurred. In recent years, the spread of wheat negative insects and worms has been rapid. For example, only a small area of ​​wheat was injured in the 186th Regiment in 1979, reaching 1,016 mu in 1980 and 3,000 mu in 1981. The adults and larvae of wheat negative plasmids mostly feed the upper epidermis and mesophyll on the front of the wheat leaves and leave the lower epidermis. Therefore, the injured places often form long, thin, white transparent films parallel to the veins, and sometimes several victims
