诱捕器引诱松墨天牛试验

The Trapping Experiment of Attracting Monochamus alternatus in Attracting Insects Ware

2002--2004年在厦门市的同安区西山、郭山马尾松纯林设置试验地，采用FJ-MA-02松墨天牛引诱剂对松墨天牛进行引诱。结果表明：4～6月诱虫量占整个诱虫量的83．3％，诱虫高峰期在5月。西山每个诱捕器2002～2004年每年平均分别引诱到60．6头、29．8头和12．2头，平均每667m^2林地引诱到1．9头、0．9头和0．5头。诱虫量分别比上一年下降了50．8％、59．1％。郭山每个诱捕器分别引诱到47．8头、20．6头和11．5头，平均每667m^2引诱到1．3头、0．5头和0．3头。诱虫量分别比上一年下降了57．0％、44．2％。说明引诱剂对降低松墨天牛种群密度，控制松墨天牛危害能发挥重要作用。

In masson pine pure plantation trial plots of Xishan and Guoshan, Tong＇ an District, Xiamen City, Monochamus alternatus was attracted by using FJ-MA-02 attractant from 2002 to 2004. The results indicated that the amount of attracted insects for 83.3 % of the total from April to June, and the maximum was in May. The average amount of each attracting insects was 60.6, 29. 8 and 12.2 individuals triennium, and 1.9, 0.9 and 0.5 individuals per mu （equal to 666.7 m^2） in Xishan mountain. The amount of attracted insects descended 50.8 % and 59.1% respectively compared to the previous year. The average amount of each attracting insects ware attracted 47.8 and 20.55 and 11.48 individuals triennium, and the average amount of attracted insects was 1.3, 0.5 and 0.3 individuals per mu in Guoshan. The amount of attracted insects descended 57.0 % and 44.2 % respectively compared to the previous year. It could explain that the attractant was beneficial to descend the population density of Monochamus alternatus and control the damage of Monochamus alternatus.
