Study on the Use of Attractant to Control Monochamus alternatus

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.
