摘要
试验表明:当年生产的规格为300 mL的瓶装蛀干类害虫引诱剂,林间诱捕松墨天牛的持效时间在23 d以上;在阴凉干燥密封条件下,储存1或2 a,其林间持效时间基本无影响;储存1 a对林间诱捕松墨天牛成虫效果无影响;储存2 a诱捕效果是新药的77.78%。不同方向诱捕效果不同;设置在东西走向山脊线上的诱捕器诱捕效果南面最高,东面次之,北面、西面较差;东、南两个方向的诱捕量占总诱捕量的68%;西面与北面的诱捕率间的差异不显著,而其余每两个方向之间的诱捕率均存在极显著差异。
rapping experiment on Monochamus alternatus with the borer attractant （M-99 attracrant） was made and the result showed the lasting time of the bottled attractant （300 mL） produced in the same year was above 23 days in the forest, Storing for one or two years in the cool, dry and airtight condition had little influence on the lasting effect. Storing for one year didn＇t influence the trapping effect while the trapping effect of the attractant stored for 2 years was 77.78 % of that of the newly produced one. The trapping effects were different in each direction. The traps placed in the south and east attracted more beetles than traps in the other two directions.
