利用抗虫品种防治小麦吸浆虫已被征明是一项经济、简便,有效的措施。近几年来吸浆虫再度猖獗成灾。陕西省植保所将近年生产上种植的101个小麦品种(系)进行了田间抗虫性鉴定和抗虫机制观察。他们发现,麦红吸浆虫喜将卵产在 It is an economical, simple and effective measure to control wheat midge with insect-resistant varieties. Midge resuscitation in recent years once again rampant disaster. Shaanxi Provincial Institute of Plant Protection in recent years, the production of 101 varieties of wheat planted on the field of insect resistance identification and observation of insect-resistant mechanism. They found that miridia likes to lay eggs in it
