Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae), a pest native to China and Korea, was discovered in North America in 1996. Currently, the only reliable strategy available for eradication and control is to cut and chip all infested trees. We evaluated various doses of the systemic insecticides azadirachtin, emamectin benzoate, imidacloprid, and thiacloprid for control of A. glabripennis in naturally infested elms (Ulmus spp.), poplars (Populus spp.), and willows (Salix spp. ) in China between 2000 and 2002. Significantly more dead A. glabripennis adults were found beneath elm and poplar trees treated with imidacloprid (in 2000 and 2001) or thiacloprid (in 2001) and beneath willow trees injected with imidacloprid or thiacloprid (in 2002) compared with control trees. In 2000, 4 mo after injection, the density of live A. glabripennis was significantly reduced in poplar trees treated with imidacloprid (90%) and in willow trees treated with imidacloprid (83%) or emamectin benzoate (71%) compared with controls. In 2001, 9 mo after injection, the density of live A. glabripennis was significantly reduced in poplar (76%) and willow (45%) trees treated with imidacloprid compared with control trees. Similarly, percentage mortality of all life stages of A. glabripennis feeding within trees was significantly higher on poplar trees 4 mo after injection with imidacloprid (64%) in 2000 and on elms (55%) and poplars (63%) 9 mo after injection with imidacloprid in 2001 compared with control trees. Imidacloprid residue levels in leaves and twigs collected at various times from 1 d to 9 mo after injection ranged from 0.27 to 0.46 ppm. Injecting A. glabripennis-infested trees with imidacloprid can result in significant mortality of adults during maturation feeding on leaves and twigs and of all life stages feeding within infested trees. Imidacloprid is translocated rapidly in infested trees and is persistent at lethal levels for several months. Although, injection with imidacloprid does not provide complete control of A. glabripennis, systemic insecticides may prove useful as part of an integrated eradication or management program.
光肩星天牛（Anoplophora glabripennis (Motschulsky)，鞘翅目：天牛科）是一种原产于中国和韩国的害虫，1996年在北美被发现。目前，唯一可靠的根除和控制策略是砍伐并粉碎所有受侵染的树木。我们于2000年至2002年期间，在中国对自然受侵染的榆树（榆属）、杨树（杨属）和柳树（柳属），评估了不同剂量的内吸性杀虫剂印楝素、甲氨基阿维菌素苯甲酸盐、吡虫啉和噻虫啉对光肩星天牛的防治效果。与对照树相比，在2000年和2001年用吡虫啉处理的榆树和杨树下方，以及2001年用噻虫啉处理的榆树和杨树下方，以及2002年注射吡虫啉或噻虫啉的柳树下方，发现死亡的光肩星天牛成虫显著更多。2000年，注射后4个月，与对照相比，用吡虫啉处理的杨树（90%）以及用吡虫啉（83%）或甲氨基阿维菌素苯甲酸盐（71%）处理的柳树中，存活的光肩星天牛密度显著降低。2001年，注射后9个月，与对照树相比，用吡虫啉处理的杨树（76%）和柳树（45%）中，存活的光肩星天牛密度显著降低。同样，2000年注射吡虫啉4个月后，在树内取食的光肩星天牛所有虫态的死亡率，在杨树上显著高于对照树（64%）；2001年注射吡虫啉9个月后，在榆树上（55%）和杨树上（63%）显著高于对照树。注射后1天至9个月不同时间采集的树叶和嫩枝中的吡虫啉残留水平在0.27至0.46 ppm之间。给受光肩星天牛侵染的树木注射吡虫啉，可导致成虫在取食树叶和嫩枝的成熟取食阶段以及在受侵染树木内取食的所有虫态出现显著死亡。吡虫啉在受侵染的树木中迅速转移，并在致死水平持续数月。虽然注射吡虫啉不能完全控制光肩星天牛，但内吸性杀虫剂可能作为综合根除或管理计划的一部分被证明是有用的。
