An Agricultural Research Service (ARS) scientist in the Pacific Northwest has joined the hunt for the infamous Asian giant hornet (AGH) — a threat to honey bees in its native territory that could also endanger honey bees in the United States if it becomes established here. AGH is also a health concern for people with bee or wasp allergies. At roughly 2 inches in length, this invasive species from Southeast Asia is the world's largest hornet. It has distinctive markings: a large orange or yellow head and black-and-orange stripes across its body. While the hornet's sting delivers a potent venom that can cause severe reactions—and in some cases, death—in some people who are allergic to bee stings, attacks against humans are rare. AGH earned its bad reputation from the way it hunts down honey bees and other insects, primarily during the late summer months when it seeks protein to feed its young.
