【 摘 要 】

We evaluated attraction of cerambycid beetle species to blends of known cerambycidpheromones to determine whether such blends could be used as effective trap lures for detectingand monitoring multiple species simultaneously. Pheromone-baited traps captured 1,358cerambycid beetles, of which 1,101 (81.1%) belonged to three species in the subfamilyCerambycinae: Neoclytus acuminatus (F.), Neoclytus mucronatus (F.), and Xylotrechus colonus(F.). Beetles of these species were significantly attracted to synthetic blends that contained theirpheromone components (isomers of 3-hydroxy-2-hexanone and/or 2,3-hexanediol), despite thepresence of pheromone components of different species, including other isomers of 2,3-hexanediol, (E/Z)-6,10-dimethyl-5,9-undecadien-2-yl acetate, and citral. In some cases attractionwas partially inhibited by the pheromone components of heterospecific species, whereas for N.acuminatus, attraction was completely inhibited when blends contained (2R*,3S*)-hexanediol,the racemic mixture of diastereomers of its pheromone, (2S,3S)-hexanediol. Among theremaining beetles captured were three species in the subfamily Lamiinae: Astyleiopus variegatus(Haldeman), Graphisurus fasciatus (Degeer), and Lepturges angulatus (LeConte). All threelamiine species were previously known to be attracted to (E/Z)-6,10-dimethyl-5,9-undecadien-2-yl acetate, and were captured in significant numbers by blends containing that compound. Ourresults suggest that different types of cerambycid pheromones can be combined to createeffective multi-species lures for use in surveillance programs that target exotic cerambycidspecies.
