(Fabricius) (Coleoptera: Dryophthoridae) is a weevil present in the Canary Islands, affecting economically important palms such as H. Wildpret and its hybrids, for which there were no trapping tools. The larvae cause the main damage by burrowing galleries in the rachis of the leaves, causing premature drying and collapse. To develop an effective trap, six trials were carried out to evaluate the effect of trap type, design, colour, height, distance and location of the trap in relation to the palm tree on captures. This study confirms that the Econex trap, green in colour, without a cover and with two ventilation holes of 2.5 cm in diameter, diametrically opposite each other and at 1 cm from the top of the base of the trap, baited with sugar cane and water, and placed between the first and second ring of green leaves of the palm canopy, is efficient in capturing . These results establish a basis for future research focused on the development of a specific trapping system based on semiochemicals to serve as a tool for detection, monitoring and mass trapping of .
（法布里修斯象甲）（鞘翅目：长蠹象科）是加那利群岛存在的一种象鼻虫，会影响经济上重要的棕榈树，如野生普雷茨椰枣及其杂交品种，此前针对这些棕榈树没有诱捕工具。幼虫通过在叶轴上挖掘虫道造成主要损害，导致叶片过早干枯和倒伏。为了开发一种有效的诱捕器，进行了六项试验，以评估诱捕器类型、设计、颜色、高度、与棕榈树的距离以及放置位置对捕获量的影响。本研究证实，Econex诱捕器颜色为绿色，无盖，有两个直径2.5厘米的通风孔，彼此相对且距诱捕器底部顶部1厘米，用甘蔗和水作诱饵，放置在棕榈树冠层第一和第二圈绿叶之间，在捕获方面效率很高。这些结果为未来的研究奠定了基础，该研究重点是开发基于信息素的特定诱捕系统，作为检测、监测和大量诱捕（法布里修斯象甲）的工具。
