Abstract
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.
Highlights
Monochamus alternatus Hope (Coleoptera: Cerambycidae) is a major vector pest insect to spread pine wood nematode, Bursaphelenchus xylophilus (Steiner & Buhrer) Nickle in eastern Asia
A variety of attractants have been developed from volatiles of host plants, which are crucial for monitoring, prevention and control of M. alternatus and to control the spread of B. xylophilus and break cycle pathways [7,8,9,10,11,12,13]
Recent field tests in China showed that two bark beetle attractants had a negative attractiveness to M. alternatus
Summary
Monochamus alternatus Hope (Coleoptera: Cerambycidae) is a major vector pest insect to spread pine wood nematode, Bursaphelenchus xylophilus (Steiner & Buhrer) Nickle in eastern Asia. Allison et al [1] note that various species of Monochamus (Coleoptera: Cerambycidae) respond to conifer volatiles and bark beetle pheromones. As one efficient and ecofriendly way to control species' population, trapping M. alternatus with an attractant is useful in the treatment of harmful species with no detriment to environment. This method has been widely utilized in forestry areas [2,3,4]. A variety of attractants have been developed from volatiles of host plants, which are crucial for monitoring, prevention and control of M. alternatus and to control the spread of B. xylophilus and break cycle pathways [7,8,9,10,11,12,13]. The results provide a theoretical basis for monitoring and controlling M. alternatus as well as inhibiting the spread of pine wilt disease
