UBC Forestry & Environmental Stewardship (FES) researchers has developed a new genomic test that can trace the Asian spongy moth—one of the biggest threats to North America’s forests—back to its source, giving officials a better chance of stopping infestations before they spread. SpongySeq is a DNA analysis tool designed to detect the Asian spongy moth, an invasive insect capable of defoliating entire forests within weeks. Unlike the European spongy moth, which has been established in North America for more than a century and spreads slowly because its females cannot fly, the Asian variety can travel long distances, feeds on a far wider range of trees—including conifers—and remains a high-risk invader with no strong natural controls. …Dr. Richard Hamelin’s team created a tool that works like a “genomic passport,” analyzing 283 specific DNA markers at once to identify a moth’s geographic origin with 97-per-cent accuracy.
