绿色威雷防治毛竹卵圆蝽的试验

Experiment on control of Hippotiscus dorsalis with 8% Cypermethrin

绿色威雷 (触破式微胶囊水悬剂 )是防治大型害虫的新型药剂。通过防治卵圆蝽 H ippotiscusdorsalis( Stal.)若虫小区试验和大田试验 ,施药后 42天小区试验平均死亡率达 96.8% ,大田试验虫株率为 0 ,防治效果显著 ,并克服了“竹腔注射”防治法降低竹材质量的缺点 ,有较好的推广应用前景。

The experiment shows Cypermethrin MC has a significant contro l effect on Hippotiscus dorsalis(Stal. ).The average mortality is 96.8% and the attacking rate is zero 42 days after sp raying,so it should be popularized.
