A. glabripennis, the Asian longhorned beetle, is a high profile invasive pest species capable of inflicting severe damage on its hosts, which include many important orchard, ornamental, and forest tree species. a Life cycle (adapted from Michael Bohne, used with permission; image of adult female courtesy of Barbara Strnadova, used with permission). b Wood dissected to expose feeding A. glabripennis larva (image courtesy of Kelli Hoover, used with permission). c, d Adult A. glabripennis (images courtesy of David Lance, used with permission). Early stage larvae are specialized wood-borers, feeding in galleries under the bark of host trees (in the subcortical tissue and phloem). Larger, later stage larvae tunnel deep into the heartwood (mature xylem) of their hosts, where they continue feeding and complete development [4]. Adults are comparatively short-lived external feeders, consuming small amounts of tissue from host leaves and twigs. A. glabripennis is broadly polyphagous on woody angiosperms. It is native to eastern Asia but has recently become established in several countries in North America, Europe, and beyond via solid wood packing material. A. glabripennis is a globally significant pest whose economic impact in the US alone, if uncontrolled, has been conservatively estimated at $889 billion (adjusted for inflation, May 2016) [5]. It is capable of attacking both healthy and susceptible trees [77] and is broadly polyphagous, feeding on at least 100 species of woody angiosperms worldwide [4, 78, 79]
