The Asian longhorned beetle, Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae: Lamiinae), is an invasive woodborer that poses a serious threat to urban and natural landscapes. In North America, this beetle is a quarantine pest, and populations are subject to eradication efforts that consist of the identification, removal, and destruction of infested host material, and removal or prophylactic treatment of high-risk host plant species. To enhance Asian longhorned beetle eradication protocols in landscapes with extensive host availability, we assessed the dispersal potential of male and female adults of varying age, mating, and nutritional status using computerized flight mills. In total, 162 individuals were tethered to computerized flight mills for a 24-h trial period to collect information on total distance flown, flight times and velocities, and number and duration of flight bouts. Adult Asian longhorned beetles (in all treatments) flew an average of 2,272 m within a 24-h period, but are capable of flying up to 13,667 m (8.5 miles). Nutrition and age had the greatest impacts on flight, with Asian longhorned beetle adults >5 d of age that had fed having greater overall flight performance than any other group. However, mating status, sex, and body size (pre-flight weight and elytron length) had a minimal effect on flight performance. This information will be useful for refining quarantine zones surrounding areas of infestation, and for providing greater specificity as to the risk the Asian longhorned beetle poses within invaded regions.
亚洲长角天牛，学名光肩星天牛（Anoplophora glabripennis (Motschulsky)）（鞘翅目：天牛科：沟胫天牛亚科），是一种入侵性蛀木害虫，对城市和自然景观构成严重威胁。在北美，这种甲虫是检疫性害虫，其种群需要通过根除措施来控制，包括识别、清除和销毁受侵染的寄主材料，以及对高风险寄主植物物种进行清除或预防性处理。为了在寄主资源丰富的景观中加强亚洲长角天牛的根除方案，我们使用计算机化飞行磨评估了不同年龄、交配状态和营养状况的雌雄成虫的扩散潜力。总共162只个体被系在计算机化飞行磨上进行为期24小时的试验，以收集飞行总距离、飞行时间和速度以及飞行回合数和持续时间等信息。亚洲长角天牛成虫（在所有处理组中）在24小时内平均飞行2272米，但能够飞行高达13667米（8.5英里）。营养和年龄对飞行的影响最大，羽化超过5天且已取食的亚洲长角天牛成虫的总体飞行表现优于其他任何组。然而，交配状态、性别和体型（飞行前体重和鞘翅长度）对飞行表现的影响最小。这些信息将有助于优化侵染区域周围的检疫区，并更具体地了解亚洲长角天牛在入侵区域内所构成的风险。
