Adult male cerambycid beetles of the subfamilies Cerambycinae and Lamiinae emit aggregation-sex pheromones that attract both sexes, and these chemicals can be utilized for quarantine surveillance for related exotic species which produce the same or similar pheromones. Here, we assess how attraction of 7 cerambycid species to pheromone-baited traps was influenced by the release rates of synthesized pheromones from polyethylene sachet emitters. Compounds tested included racemic 3-hydroxyhexan-2-one, the (R)-enantiomer of which is the sole or major pheromone component of numerous cerambycine species, and 2 compounds that are pheromone components of many lamiine species: (E)-6,10-dimethyl-5,9-undecadien-2-yl acetate (fuscumol acetate) and 6-methylhept-5-en-2-ol (sulcatol). We confirmed release rates of these compounds could be manipulated by varying the doses loaded into emitters. Various doses and concentrations, ranging from very dilute to the neat compounds, were then tested in field trials. Several species were most strongly attracted to the highest dose of a tested compound, one species to an intermediate dose, while another species was equally attracted regardless of dose. Our results demonstrate the importance of characterizing dose–response relationships for cerambycid species targeted by pheromone-based trapping.
