为了保护水曲柳，需要采取有效的措施。来自祖母绿白蜡树蛀虫，平翅窄吉丁虫（鞘翅目：吉丁虫科），一种入侵性的甲虫，已经杀死了数百万的北美白蜡树（白蜡树属）。树我们随机分配175灰树（直径11.5-48.1厘米）在25块位于密歇根州的三个研究地点之一，在2007年5月的7种杀虫剂治疗。处理包括1）树干注射甲氨基阿维菌素苯甲酸盐; 2）树干注射吡虫啉; 3）在有或没有Pentra-Bark（一种农业表面活性剂）的情况下，树干基部喷洒呋虫胺; 5）在有或没有Pentra-Bark的情况下，树干基部喷洒吡虫啉;或（7）对照。叶片杀虫剂残留量（酶联免疫吸附测定法）和叶片对成虫的毒力。在处理后的3-4周间隔定量扁翅目昆虫（4-D生物测定）。2007年秋季，7个街区的树木被砍伐并取样，以量化A。平翅蛾幼虫密度2008年春季，剩下的一半街区被收回。在2008年夏季重复进行生物测定和残留物分析，然后在冬季对所有树木进行采样以评估幼虫密度。甲氨基阿维菌素苯甲酸盐处理过的树木叶片对A. planipennis，幼虫密度= 2年，可以降低成本或与治疗相关的后勤问题。
Effective methods are needed to protect ash trees (Fraxinus spp.) from emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), an invasive buprestid that has killed millions of North American ash (Fraxinus spp.) trees. We randomly assigned 175 ash trees (11.5-48.1 cm in diameter) in 25 blocks located in three study sites in Michigan to one of seven insecticide treatments in May 2007. Treatments included 1) trunk-injected emamectin benzoate; 2) trunk-injected imidacloprid; 3) basal trunk spray of dinotefuran with or 4) without Pentra-Bark, an agricultural surfactant; 5) basal trunk spray of imidacloprid with or 6) without Pentra-Bark; or (7) control. Foliar insecticide residues (enzyme-linked immunosorbent assay) and toxicity of leaves to adult A. planipennis (4-d bioassays) were quantified at 3-4-wk intervals posttreatment. Seven blocks of trees were felled and sampled in fall 2007 to quantify A. planipennis larval density. Half of the remaining blocks were retreated in spring 2008. Bioassays and residue analyses were repeated in summer 2008, and then all trees were sampled to assess larval density in winter. Foliage from emamectin benzoate-treated trees was highly toxic to adult A. planipennis, and larval density was = 2 yr may reduce costs or logistical issues associated with treatment.
