摘要
在观察生物学特性的基础上,通过室内和田间多种药剂不同的施药方式防治柳厚壁叶蜂幼虫试验,筛选出防治柳厚壁叶蜂最佳的药剂为40%的氧化乐果乳油1000倍液树冠喷雾和原液涂干,其次为40%的高渗久效磷乳油原液涂干和20%的毒死蜱.辛乳油1000倍液树冠喷雾,其田间校正防效均达95%以上。
On the base of observing biological characteristics and by the test of using many kinds of insecticides with different modes in the room and field in order to control pontania dolichura, the best methods are picked out by 40% omethoate 1000-fold spraying the crown and daubing the trunk with raw liquid ,the second are 40% high permeable monocrotophos to daub the trunk and 20% chlorpyrifos ＋phoxin 1000-fold to spray the crown. Their rectifying efficacies for pontania dolichura are above 95% in the field.
