利用引诱剂诱捕松墨天牛等甲虫的研究

Study on the Use of Attractant to Control Monochamus alternatus

松墨天牛(Monochamus alternatus Hope)是马尾松、湿地松、黑松及日本赤松的主要蛀干害虫,也是台湾五针松、北美短叶松、日本冷杉、欧洲云杉、柳杉等主要蛀干害虫之一。该虫在我国分布于西藏以东、河北以南,东至台湾、南至广东;国外分布于日本、朝鲜、越南、老挝。近10年来,我国广东、广西、湖南、江西、安徽等省(区)多处发生天牛危害。

Attractants can be used to trap mass Monochamus alternatus during the period of feeding and oviposition, and also other beetles, such as Arhopalus unicolor, Hyposipalus gigaus, Shirahoshizo patruelis, etc. Compared with the attractant of Japanese product, the trapping rate through using the self-prepared attractant to the above-mentioned beetles has increased by 0.29, 2.5, and 1.2 times respectively. Having been controlled by means of the attractant in Pine stands, the population density of M. alternatus, etc, and the withered rate of Pine trees can be greatly reduced. After putting attractant I into Pine trees and keeping for two months, the trapping effect is remarkable, especially in the first month.
