Abstract:  Monochamus alternatus Hope is the primary vector for spreading pine wilt disease. Use of attractants in the control of M. alternatus population is effective and pollution-free. In this study, the field test was conducted to evaluate the attractiveness of M. alternatus attractant combined with six kinds of bark beetle attractants to M. alternatus adults. The results showed that there was no significant difference among the combinations of each of bark beetle attractants for Tomicus minor Hartig (3-carene-10-ol), Ips typographus Linnaeus (2-methyl-3-buten-2-ol), Scolytus multistriatus Marsham (4-methyl-3-eptanol), and T. piniperda Linnaeus (verbenol) with M. alternatus attractant (P<0.05). The combinations of attractants for either Dendroctonus brevicomis LeConte (exo-brevicomin) or D. pseudotsugae (1-methylcyclohex-2-en-l-ol) with M. alternatus attractant were less attractive to M. alternatus. Compared with M. alternatus attractant used only, the combination of either D. brevicomis or D. pseudotsugae with M. alternatus attractant was also less attractive as indicated by the species and number of wood-boring beetle individuals captured.

Key words:  Monochamus alternatus, bark beetles, attractant, trapping, wood-boring beetles
