小麦红吸浆虫是为害麦类作物的世界性害虫,2004年在北京市顺义区首次发现,通过3年的系统监测及普查,摸清了小麦红吸浆虫的发生规律。通过不同药剂、不同配方、不同方法、不同虫态防治试验示范、总结出了适宜全区防治吸浆虫的方式方法。根据物候法找出了在小麦抽穗达到50%～70%时为最佳防治时期。筛选出了春季小麦起身拔节期防蛹,可用3%辛硫磷颗粒剂,每667m25kg均匀撒施或40%辛硫磷EC每667m2250ml加细沙15kg拌毒土均匀撒施(撒药后必须及时浇灌)。成虫防治用4.5%高效氯氰菊酯EC30ml+80%敌敌畏EC50ml用机动喷雾器或手压喷雾器喷雾防治。通过在全区开展技术培训、广泛宣传、试验示范带动等措施,推动全区小麦吸浆虫防治。全区3年累计培训2000多人次,发放宣传材料4000多份,累计防治1.12万hm2,增加小麦产量1078.2万kg,增加纯收入1420.4万元,经济效益显著。
Wheat pollosid is a worldwide pest of wheat crops. In 2004, it was first discovered in Shunyi District of Beijing. Through 3 years of systematic monitoring and census, the occurrence of wheat pollination was found out. Through different agents, different formulations, different methods, different insect prevention and control experiment demonstration, summed up the appropriate way to prevent and control Midge. According to the phenology method, it was found that when the heading of wheat reaches 50% ~ 70%, it is the best control period. Screening of the spring wheat rose at jointing stage pupae, available 3% phoxim granules, evenly spread every 667m25kg or 40% phoxim EC 667m2250ml per 667m2 plus fine sand mixed soil evenly spread (after the drug must be timely water). Adult control with 4.5% beta-cypermethrin EC30ml + 80% Dichlorvos EC50ml spray with a mobile or hand-pressure sprayer spray control. Through the region to carry out technical training, extensive publicity, pilot demonstration driven by other measures to promote the control of wheat midge throughout the region. Over the past three years, the district has trained more than 2,000 people and distributed over 4,000 propaganda materials to prevent and cure 11,200 hm2 in total. The output of wheat increased by 10,782,000 kg and the net income increased by 14,020,400 yuan, bringing remarkable economic benefits.
