- Abstract
Information on species assemblages of metallic wood-boring beetles (Coleoptera: Buprestidae) in forested habitats in North America is relatively scarce, likely reflecting the difficulty of effectively trapping and accurately identifying species. We identified buprestid species captured on four baited traps placed in each of 12 sites representing four common forest cover types in five Michigan counties. Overstory vegetation was dominated by ash ( Fraxinus spp.), maple ( Acer spp.), oak ( Quercus spp.), or poplar ( Populus spp.) trees (three sites per cover type). A total of 1656 buprestids representing 28 species were captured on sticky purple prism traps baited with either cis-3-hexenol plus Manuka oil or 3R-hydroxyhexane-2-one plus ethanol from May to August 2014. Buprestid species richness ranged from 6 to 13 species per site. PERMANOVA results showed that buprestid species composition differed among forest cover types ( P < 0.005). The invasive Agrilus sulcicollis Lacordaire and the native Chrysobothris femorata Olivier species group were significant indicators of oak sites, while Agrilus obsoletoguttatus Gory was a significant indicator of maple sites. Nonmetric multidimensional scaling showed that abundance of captured buprestids was influenced by availability of fresh snags and coarse woody debris. Our results indicate that trapping can provide an efficient means to assess assemblages of phloem- or wood-boring buprestids.
