采用树干注孔法防治分月扇舟蛾试验

Trials on Clostera anastomosis(Linaens)control with trunk syringe

将40%久效磷乳油和50%甲胺磷乳油稀释不同倍数后,用树干注射机注入树干基部,进行室外林间嫩枝接虫和采集叶片饲养室内幼虫试验结果表明:2种药剂对分月扇舟蛾均具有良好的杀虫效果,甲胺磷的防治效果优于久效磷,同一药剂,注入的浓度越高,杀虫速度越快。

By injection of monocrotophos and methamidophos solutions of different concentrations into the base of tree with trunk syringe,trial results afterwards indicate that both demonstrate favorable effects in Clostera anastomosis(Linaens)control and methamidophos excels monocrotophos effectively.And as for each preparation,the more concentrated,the faster it kills te pests.
