浏阳市北盛镇稻飞虱发生规律及防治技术研究(毕业论文7500字)
摘 要：稻飞虱是一种远距离迁飞性水稻害虫，近30年来在湖南地区发生面积扩大，暴发频率增加，给湖南的水稻生产带来了严重危害，其特点是早稻偏轻，晚稻偏重。本文通过2010年浏阳市北盛镇的农技虫情简报及其历史资料，基于昆虫学的理论与方法，对该地区的飞虱发生规律进行了研究，并通过目前主要的飞虱防治技术，应用田间药效对比试验，探索杀虫剂对飞虱的防治作用并提出科学性的飞虱防治建议。由A、B、C、D、E五种处理结果显示： 50﹪噻嗪•毒死蜱EC在实践中最具推广价值，而当虫口基数不是很大时可以适当考虑使用10%哌虫啶。

Studies on Occurrent Regularity and Control Planthopper of Beisheng Liuyang
Abstract：Rice planthopper is a remote migratory rise pest, which expanded in Hunan province in nearly 30 years.The frequency of outbreak has increased,bringing great harm to rice in Hunan . Its characteristics were light in early rice and serious in in late rice.Based on theories and methods of entomology, and conbined with agricultural technique pest briefing and historical information of Beisheng Town, LiuYang City in 2010, this paper has studied the occurrence regulation of planthopper over the region.Besides, through the present main prevention techniques , appling field efficacy contrast tests,exploring the effects of insecticides , scientific controlling countermeasures were put forward. A、B、C、D、E five kinds of processing results showed that 50% thiazine.chlorpyrifos EC have spreading value most in practice,while10% perospirone bug acetamiprid could take into account when population base was not very big.
Key words：Rice；planthopper；occurrence regulation；prevention techniques
