| dc.description.abstract | The hemlock woolly adelgid (HWA), <i>Adelges tsugae</i>, is an invasive pest of <i>Tsuga</i> spp. in eastern North America. <i>Scymnus coniferarum</i> is a predaceous beetle that was collected from HWA in the western United States. Limited knowledge of this insect in its native habitat led to studies to evaluate its potential for biological control of HWA. Seasonal abundance was sampled at six sites in Tacoma, WA, twice monthly, for one year on different host trees of potential adelgid prey. Tree species included <i>Pseudotsuga menziesii</i>, <i>Pinus contorta</i>, <i>Pinus monticola</i>, and <i>Tsuga heterophylla</i>. <i>Scymnus coniferarum</i> adults were found on all conifer species, except <i>P. menziesii</i>. Each conifer species supported a different adelgid species, suggesting <i>S. coniferarum</i> feeds on multiple adelgid species. More <i>S. coniferarum</i> were found on pine than hemlock. DNA barcoding of <i>S. coniferarum</i> found two distinct clusters that differed by 6% divergence. Beetles in each cluster were co-habiting the same conifer species, and they could not be distinguished morphologically. Further taxonomic studies are needed to understand the significance of DNA barcode sequence divergence. Because <i>S. coniferarum</i> was more frequently associated with pine adelgids than HWA, and because of remaining taxonomic uncertainty, <i>S. coniferarum</i> may not be suitable for HWA biological control. | en |
