Capture Efficacy of 3 Longhorn Beetle Pheromones and Cubeb Oil on Cerambycidae
To screen the efficient attractants of different Cerambycidae species,and monitoring species and individuals of cerambycid beetles in pine forests,especially the population dynamics of potential vector longhorn beetles of pine wilt disease.Three cerambycid pheromones of 2-(undecyloxy)ethanol(Monochamol),(E)-6,10-dimethyl-5,9-undecadien-2-ol(E/Z-fuscumol),(E)-6,10-dimethyl-5,9-undecadien-2-yl acetate(E/Z-fuscu-mol acetate)and cubeb oil were used as attractants,supplemented by black intercept panel traps for field trapping experiments.The findings revealed that cubeb oil increased attractive effect of(E)-6,10-dimethyl-5,9-undecadi-en-2-ol(E/Z-fuscumol)+(E)-6,10-dimethyl-5,9-undecadien-2-yl acetate(E/Z-fuscumol acetate)on Lepturinae,reduced individual number of 2-(undecyloxy)ethanol(Monochamol)on Monochamus saltuarius.The combina-tion of E/Z-fuscumol+E/Z-fuscumol acetate with Monochamol and/or cubeb oil increased the number of cap-tured cerambycid species.In practical application,plant volatiles should also be selected as pheromone synergists according to specific cerambycid species.The combination of Monochamol+E/Z fuscumol acetate+E/Z fuscu-mol can be used to improve the trapping efficiency in monitoring and control of M.saltuarius and M.urussovi.To reduce the cost,a single Monochamol lure can be used in general cerambycid population monitoring survey.
