The Asian long-horned beetle Anoplophora glabripennis , native to China and Korea, is a major pest of many hardwood trees,… The glossy black adults are large, 17—40 mm 0. The long antennae each have 11 segments and are 1. The base of each segment is pale blue-white, grading distally away from the centre of the body to black. Adults are active from April or May through October. New adults feed on twigs or leaf veins and petioles leaf stalks for approximately two weeks before mating. Adults locate host trees by using visual or chemical cues and detect mates by using both short-range and contact pheromones.

Boulevard, New Jersey. Moreover, live beetles have been found at the ports and in warehouses in several different states. Reason s Why it has Become Established: Because the ALB has an extended egg-through-larval transition, the organism remains virtually invisible for up to one year. During this period it is difficult to detect and may be easily inadvertently transported by human activity especially in wood packing materials. Once delivered to a potential colonization site in the temperate zone or North America , a ready supply of host arboreal species is virtually guaranteed.
