Abstract

Most of the current understanding of the orientation and communication of jewel beetles arose from research on the Asian emerald ash borer (EAB), Agrilus planipennis, which has become one of the most destructive invasive forest insect pests in history following its introduction to North America and European Russia. From a European perspective, a number of jewel beetles have a high invasive risk similar to that of the emerald ash borer, including the potential threat of the bronze birch borer Agrilus anxius, the goldspotted oak borer Agrilus auroguttatus, and the twolined chestnut borer Agrilus bilineatus. Native jewel beetles expanding their geographic range include the cypress jewel beetle Ovalisia festiva and the black-banded oak borer Coraebus florentinus. Other native species are increasing in their importance, including the flathead oak borer Coraebus undatus, the two-spotted oak borer Agrilus biguttatus, the flatheaded beech borer Agrilus viridis and Agrilus cuprescens. Commonly used prism and multi-funnel trap designs and other promising experimental trap designs have been tested and compared in the US and in Europe. One factor considered has been colouration, typically purple and green. Another is olfactory attraction, both to plant volatiles and extracts such as (Z)-3-hexenol, Manuka oil, Phoebe oil and Cubeb oil, and also to pheromones such as (Z)-3-lactone, for emerald ash borer. Field observations have been made of mating and host-finding behaviours of oak buprestids based upon visual stimuli in North America and Europe. By using pinned dead EAB models, visual mating approaches have been observed by males of Agrilus biguttatus, Agrilus sulcicollis and Agrilus angustulus, which is a behaviour similar to that previously observed in EAB. Green plastic-covered branch-traps significantly out-performed other trap designs and caught more Agrilus jewel beetles if an artificial visual decoy that copies a beetle body was included. A higher fidelity decoy offered the same distinctive light-scattering pattern as real resting EAB females and elicited the full sequence of stereotypical male mating flight behaviour of EAB and A. biguttatus from up to 1 m away. An optimization of visual, olfactory and other possible stimuli has likely not yet been achieved. More sophisticated trap designs could lead to more sensitive detection capabilities with increased selectivity.
改进捕虫方法,加强对本地和外来物种的监测
目前对宝石甲虫的定位和交流的认识大多来自于对亚洲祖母绿灰螟(Agrilus planipennis)的研究,该昆虫自引入北美和欧洲俄罗斯以来已成为历史上最具破坏性的入侵森林害虫之一。从欧洲的角度来看,许多宝石甲虫具有与祖母绿灰螟虫相似的高入侵风险,包括青铜桦树螟虫Agrilus焦虑症,金斑橡树螟虫Agrilus auroguttatus和双线栗树螟虫Agrilus bilineatus的潜在威胁。扩大其地理范围的本地宝石甲虫包括柏树宝石甲虫Ovalisia festiva和黑带橡树蛀虫Coraebus florentinus。其他本地物种的重要性也在增加,包括平头橡树螟虫Coraebus undatus、双斑橡树螟Agrilus biguttatus、平头山毛榉螟Agrilus viridis和Agrilus cuprescens。常用的棱镜和多漏斗捕集器设计和其他有前途的实验捕集器设计已经在美国和欧洲进行了测试和比较。考虑的一个因素是颜色,通常是紫色和绿色。另一个是嗅觉吸引力,对植物挥发物和提取物,如(Z)-3-己烯醇、麦卢卡油、菲比油和cubbeb油,以及信息素,如祖母绿灰螟的(Z)-3-内酯都有吸引力。在北美和欧洲进行了基于视觉刺激的柞蚕交配和寄主寻找行为的实地观察。通过钉死的EAB模型,我们观察到了biguttatus Agrilus sulcicollis和Agrilus angustulus雄性Agrilus的视觉交配方式,这种行为与之前在EAB中观察到的行为相似。绿色塑料覆盖的树枝陷阱明显优于其他陷阱设计,如果包括复制甲虫身体的人工视觉诱饵,则捕获更多的Agrilus宝石甲虫。一个高保真度的诱饵提供了与真正休息的EAB雌性相同的独特光散射模式,并诱导了EAB和biguttatus在1米外的典型雄性交配飞行行为的完整序列。视觉、嗅觉和其他可能的刺激的优化可能还没有实现。更复杂的陷阱设计可以带来更灵敏的探测能力和更高的选择性。

期刊介绍: The journal is inclusive of all subjects, geographical zones and study locations, including trees in urban environments, plantations and natural forests. We welcome papers that consider economic, environmental and social factors and, in particular, studies that take an integrated approach to sustainable management. In considering suitability for publication, attention is given to the originality of contributions and their likely impact on policy and practice, as well as their contribution to the development of knowledge. Special Issues - each year one edition of Forestry will be a Special Issue and will focus on one subject in detail; this will usually be by publication of the proceedings of an international meeting.
