洛南县松阿扁叶蜂发生规律及防治技术研究

Occurrence Regularity and Control Techniques of Acantholyda posticalis in Luonan

研究了松阿扁叶蜂在洛南县油松林的生活史、生活习性等规律,并筛选出有效防治方法,表明地面药剂垦复防治效果达90%以上;在郁闭度0.7以上的油松林分内,防治3龄前幼虫用药量为15kg.hm-2敌敌畏烟剂、林丹烟剂效果分别达97%;树冠喷雾40%氧化乐果乳油1000倍液、3%高渗苯氧威乳油3500倍液、25%灭幼脲悬浮剂2000倍液、蚜螨敌1500倍液、1.2%苦烟乳油2000倍液,防治效果分别在84%以上。

Based on the study of the biological character, life span and habits, effective methods to con- trol the pest was selected. The result showed that ground condition improvement would be 90% in control effect in the forest with canopy closure over 0.7, the larvae of Acantholyda posticalis before three years could be effectively controlled by 97% by means of smoky pesticide, such as DDVP and lindane. 40% oil omethoate solution at 1000 times, 3% fenoxycarb solution at 3500 times, 25% Chlorbenzurol at 2000 times, aphid killer solution at 1500 times or 1.2% insect killer at 2000 times can effectively control Acantholyda posticalis over 84 %.
