利用引诱剂监测林木主要蛀干害虫

Using attractants monitor main trunk-boring insects in forest

于2004-2006年间对浙江省乐清市林木蛀干害虫种类进行调查,结果显示该辖区共有47种蛀干害虫,隶属于8科41属。重点对松墨天牛Monochamus alternatus Hope、削尾材小蠹Xyleborus mutilatus Blandford等的成虫活动期林间种群数量动态进行监测。结果表明,松墨天牛林间活动期为4月下旬至11月中旬,6月上旬为高峰期,其诱获的成虫数占监测总数的41.1%,初步显示该虫在浙南地区松林内的种群数量变化规律。同时,还初步了解到削尾材小蠹成虫的活动规律。

The forest tree trunk-boring insect pests on forest trees were investigated during 2004 - 2006, a total of 47 species belonging to 1 order, 8 families and 41 genera were found in Yueqing City, Zhejiang Province. The adult population dynamics of Monochamus alternatus and Xyleborus mutilatus in forest trees were monitored. The results showed that the adult active period of M. a/ternatus in forest trees were late April to mid November, and the peak period were early June, the trapped adult specimens occupied 41.1% of the monitored total specimens. Meanwhile, population dynamics of X. mutilatus was preliminarily monitored.
