松原木松墨天牛和松小蠹熏杀试验

Experiment on Smoking Monochamus alernatus Hope and Ortnomicus erosus Wollaston of Pine Log

采用熏蒸箱或帐幕法,投药量每立方松原本使用50g敌敌畏、添加450g助燃剂,防治木材害虫松墨天牛幼虫和松小蠹幼虫、成虫,熏蒸5d后的死亡率,帐幕法分别为33.42%和65.96%,熏蒸箱法分别为15.21%和96.20%,防治效果较差。敌敌畏烟剂防治木材内的蛀虫尚需进一步试验。

USing fumigation chamber or tent method with 50g/m^3 nuvan and 450g com-bustion-supporting agent to control Monochamus alernatus Hope larva, Ortnomicus erosus Wolla-ston larva and adult on pine log showed that the mortality after 5 days fumigation was res-pectively 33.42% and 65.96% for tent method, 15.21% and 96.20% for fumigation chamber.Moth inside timber controlled by nuvan smoking agent need to be more studies.
