Abstract
International commerce is an important pathway by which exotic and potentially invasive insects are introduced to new areas. Invasive insects threaten managed and natural ecosystems, especially forests. Wood boring beetles are of particular concern because immature forms may be concealed in solid wood material or consumer products and may escape detection by regulatory personnel. Insect families Buprestidae, Cerambycidae and subfamily Scolytinae are of particular interests for the damages they caused. Early detection of invasive wood boring beetles is vital to mitigating impacts and slowing their spread. Baited trapping techniques are used in many surveys, however many traps that are currently available are only effective at trapping a limited number of taxa. We assessed the effect of generic sex-attractant pheromones and host volatiles on capture of wood boring beetles by green funnel traps. We found that adding chemical attractants for the family Cerambycidae and subfamily Scolytinae to green funnel traps increased trap capture across multiple taxa. Our results may improve surveys for multiple taxa, using one trap design, thus streamlining surveys for invasive species.
