褐稻虱具有长距离迁飞特性.掌握其迁飞的时期、条件与成灾作用,对认识这一稻虫的发生规律和制定防治对策是极为必要的.我们在研究褐稻虱地方发生规律的同时,探讨了褐稻虱的迁飞规律.本文就建阳地区近两年来褐稻虱迁入和迁出的一些观察,阐述迁飞特性,研究迁飞规.通过海捕、空捕、高山网捕都有力地证明褐稻虱具有长程迁飞的特点.但要确定其迁入或迁出某一具体地域,并给这个地区可能带来的影响,还必须立足一个具体地区深入研究迁入或迁出的规律.近两年来,我们从建阳一个地区的角度探讨迁飞的地面征象,结果有如下十个方面:
Brown rice louse has the characteristics of long-distance migration.Get its migration time, conditions and disaster effects, to understand the occurrence of this rice pest and to develop prevention and control measures is extremely necessary.We study the law of brown planthopper At the same time, we discussed the migration rules of brown planthopper (BPH) .In this paper, we observed the migration of brown planthopper (BPH) in Jianyang area in recent two years, Alpine netting is a powerful demonstration of the long-range migration of brown planthopper, but it must also be based on a specific area for further studies to determine its impact on migration into or out of a particular area In the past two years, we explored the ground signs of relocation from the perspective of a region in Jianyang. The results have the following ten aspects:
