小麦吸浆虫,属双翅目瘿蚊科,为世界性害虫,也是危害小麦的主要害虫之一。国内发生有十几种,危害小麦的主要有麦红吸浆虫和麦黄吸浆虫两种,其中以前者发生最普遍,危害最严重。以幼虫吮吸麦粒浆汁,造成瘪粒甚至成空壳而减产,一般损失10%～20%,严重的减产60%～80%,甚至绝收。危害特点两种吸浆虫均以幼虫潜伏在小麦颖壳内,吸食正在灌浆的麦粒汁液为害,被吸浆虫为害的小麦,其长势和穗型大小不受影响,且由于麦粒被吸空,麦秆表现直立不倒,具有假旺盛的长势。受害小麦粒浆液被吸食而变瘦,出现瘪粒,甚至成空壳。
Wheat midge, belonging to the Diptera family of mosquitoes, is a worldwide pest, but also one of the major pests endangering wheat. There are dozens of domestic occurrences, the main wheat endangered wheat Midge and Apodemus two, of which the former occurred the most common, the most serious harm. To larvae sucking grain juice, resulting in shriveled even empty shell and reduced production, the general loss of 10% to 20%, a serious cut of 60% to 80%, or even absolute. Harmful characteristics of two kinds of midges are larvae lurking in the wheat glume shell, smoking is being grouted grain juice damage, to be inhaled askew-infested wheat, its growth and panicle size is not affected, and because the grains are sucked empty, straw Upright performance does not fall, with a strong exuberant growth. Victims of wheat pulp slurry was thin and lean, appear shriveled, and even into the empty shell.
