Effect of European Hylesinus Beetle Attractants on Monochamus Alternatus Hope (Coleoptera: Cerambycidae) in China Forests

In this study, we firstly performed a comparative analysis of five attractants, four European products and one Chinese product, for their attraction to adult Monochamus alternatus Hope and other insects in the forestry area in Fuyang, Zhejiang, China. Research results show that among these 5 different lures to trap M. alternatus, Seudenol trapped the largest amount and species of insects. In terms of efficiency, M-99 (the Chinese product) and exobrevicomin are the best, Seudenol, 2-Methyl-3-buten-2-ol and ipsenol, ipsdienol and cis-verbenol the second, while the control group is the worst. Based on the attractive effect, 2-Methyl-3-buten-2-ol is distinctly different from the other four lures according to the statistical analysis, while there is no significant difference among the other four lures. This is probably due to factors such as the lure composition, natural environment, host plant, geographical difference, and geographical isolation of Monochamus alternatus Hope. These five lures not only showed effect on the Monochamus alternatus Hope, but also had attraction to borer pests, such as Spondylis buprestoide and Monochamus bimaculatus Gahan. Among them, Seudenol trapped the largest amount of S. buprestoides and M. bimaculatus Gahan.
