小麦吸浆虫属于双翅目瘿蚊科,主要以幼虫潜伏在小麦颖壳内吸食正在灌浆的麦粒汁液,造成秕粒、空壳,导致小麦减产、品质下降,一般发生田块可减产10%—30%,严重的减产达70%以上,甚至绝收,是小麦上的一种毁灭性的害虫。多年来,小麦吸浆虫由于其调查方法的繁杂和防治技术的特殊性,给小麦吸浆虫的防治带来一定的困难。本文借鉴大量研究文献,对几种小麦吸浆虫的调查新方法:袋筛箩瓷盘淘土法、粘板诱 Belonging to Diptera, Apodemus divaricatus, the larva lurks mainly in the wheat glume shell and ingests the grain-filling grain juice, resulting in grains and shells, which leads to the decrease of wheat yield and the quality decline. Generally, 10% 30%, a serious reduction of more than 70%, or even income, is a devastating pest on wheat. For many years, due to its complicated survey methods and the particularity of the prevention and control technology, the midge of wheat has brought certain difficulties to the control of the midge of wheat. This article draws on a large number of research literature, the new method of investigation of several kinds of wheat midge insects: bag sieve porcelain pan and earthenware method,
