我国谷子主产区粟叶甲为害现状与防治

针对我国谷子主产区谷子粟叶甲近年来发生为害及造成的损失和日趋渐重的现状,在发生、为害、药剂和综合防治措施等方面进行了综述,以期为该虫的适时防治和谷子产业的良性发展提供参考与指导。近10 a来,粟叶甲在我国北方谷子作物上普遍偏重发生,产量损失可达10%～15%,已上升为谷子的主要害虫之一。旱作秸秆覆盖起到了积极的稳产作用,但给害虫提供了适宜的繁衍温床,加重了粟叶甲为害的发生几率。现有谷子栽培品种间粟叶甲有虫率存在程度不同的差异,应重视这些品种的利用和改良,在此基础上深入开展谷子抗虫育种方面的工作,将成为抗粟叶甲危害的捷径和方向。

Current Situation of Millet Oulema Tristis Herbst and Control Techniques in the Main Producing Areas

In viewof increasingly serious damage status of the millet in main producing areas,millet leaf beetle damage and losses caused in recent years,infection,damage,comprehensive chemical control and control measures were reviewed to provide timely prevention for millet industry.In the past decade,millet leaf beetle as one of the major pests of millet,in northern China became popular serious and brought yield losses up to 10%-15%.Strawmulch has played a positive role for stable production,but to provide pest suitable multiply breeding ground and increased millet leaf beetle hazard occurrence.There are varying degrees in parasite rate for available millet cultivatar varieties existing,so,importance should be attached to these varieties' utilization and improvement.In-depth millet insect resistance breeding work will become shortcuts and direction for the anti-poppy leafA hazard.
