Invasive species are a perpetual threat to U.S. agriculture, natural resources, and public health, and we're seemingly inundated with new ones every time you open the news. Is progress possible, or are we destined to spin on an invasive species hamster wheel?
A team of researchers at Montana State University analyzed environmental and habitat conditions across four states in the Pacific Northwest to create a county-by-county risk rating for establishment of the invasive giant hornet Vespa mandarinia.
When scientists discovered specimens of the invasive giant hornet Vespa mandarinia on both sides of the border between Washington and British Columbia in 2019, they sought to find out how they arrived from Asia. Analysis of their mitochondrial DNA provided an interesting twist: The hornets on each side of the border likely did not come from the same location in Asia.
A new key to the genus Vespa includes dozens of close-up photos to help users sort through and ID potential invasive species like the Asian giant hornet.
