The bronze birch borer, Agrilus anxius, is a North American buprestid pest of stressed or weakened birch trees (Betula spp.) and is considered a major threat to European birch species as a potentially adventive insect. Laboratory bioassays and field trapping experiments were conducted to elucidate potential visual and chemical cues used in host location in this species. Birch bark and foliar volatiles (Betula papyrifera Marsh) and a pheromone attractive to the congener, A. planipennis, (3Z)-dodecen-12-olide ((3Z)-lactone), were tested along with a girdled tree treatment, with purple sticky prism traps. Only the girdled tree treatment with purple traps elicited significant attraction by adult A. anxius. Various colours of sticky traps were tested with host volatiles attractive to A. planipennis; results showed that unbaited green sticky traps were more attractive than other colours tested; none of the host volatiles tested increased trap capture with any traps. Examination of foliage and bark of B. papyrifera by GC/EAD, and GC/MS techniques has identified several EAD-active compounds with (3Z)-hexenol and (5 S,7 S)-conophthorin as the most EAD-active molecules. Neither compound, however, alone or combined, elicited significant trap capture on green sticky prism traps; these compounds may find importance as synergists once the pheromone for A. anxius is identified.

树木环剥和寄主树木挥发物为青铜白桦bore Agrilus anxius Gory（鞘翅目：Buprestidae）提供了有用的陷阱。

青铜白桦bore（Agrilus anxius）是北美重瓣或弱化桦树（Betula spp。）的黄b害虫，被认为是欧洲桦树种的主要威胁，是一种潜在的外来昆虫。进行了实验室生物测定和野外诱捕实验，以阐明该物种宿主位置中可能使用的视觉和化学线索。白桦树皮和叶面挥发物（桦木沼泽）和一种吸引同源物A. planipennis（3 Z）-十二碳烯12-内酰胺（（3 Z）-内酯），以及带有紫色粘性棱镜陷阱的环剥树处理方法进行了测试。只有用紫色陷阱进行的环剥处理才能引起成年的A. anxius的明显吸引力。测试了各种颜色的粘性捕集阱的宿主挥发物对拟南芥的吸引力; 结果显示，未诱饵的绿色粘性陷阱比其他测试的颜色更具吸引力。所测试的主机挥发物均未使用任何捕集阱提高捕集阱捕获率。通过GC / EAD和草甘膦技术对纸莎草芽孢杆菌的叶和树皮进行检测，已鉴定出几种具有（3 Z）-己烯酚和（5 S，7 S）-视黄酮为最具有EAD活性的分子。但是，无论是单独还是组合使用，都不会在绿色粘性棱镜阱上引起明显的阱捕获。一旦确定了A. anxius的信息素，这些化合物可能会作为增效剂发挥重要作用。
