小麦吸浆虫是小麦生产上一种毁灭性害虫,其以老熟幼虫在土中结圆茧越夏越冬,生活历期长达10个多月,并有多年休眠习性。自2004年在我市发生以来,每年发生面积都在6万亩以上,严重发生年份造成部分地块减产,是小麦生产上一种重要虫害。小麦吸浆虫虫体极小,主要以幼虫在麦田土壤中结茧越冬,第二年4月中下旬到地面化蛹,5月初羽化为成虫,在麦穗上产卵,孵化成幼虫后钻入麦穗颖壳内吸食小麦浆液危害,致使麦粒干瘪、秕瘦。因虫体小,长年在土
Wheat midge is a devastating pest in wheat production. With mature larvae cocoon knot in the soil over the summer and winter, the life span of up to 10 months, and many years of dormancy. Since the occurrence in our city in 2004, the annual area has been more than 60,000 mu. The serious occurrence of the year resulted in the reduction of some plots. It is an important pest in wheat production. Infection of wheat midge was extremely small. The larva mainly cocooned in the wheat field soil overwintering. In the second year of April, the pupae were ground to pupate. In early May, the parasites became adults and spawned on the ears of wheat. After hatching into larva, Spikenard suck the wheat pulp slurry harm, resulting in shriveled wheat, thin skinny. Due to small insects, for many years in the soil
