Palm weevils, spp., are destructive pests of native, ornamental, and agricultural palm species. Of the 10 recognized species, two of the most injurious species, and , both of which have spread beyond their native range, are the best studied. Due to its greater global spread and damage to edible date industries in the Middle East, has received more research interest. Integrated pest management programs utilize traps baited with aggregation pheromone, removal of infested palms, and insecticides. However, weevil control is costly, development of resistance to insecticides is problematic, and program efficacy can be impaired because early detection of infestations is difficult. The genome of has been sequenced, and omics research is providing insight into pheromone communication and changes in volatile and metabolism profiles of weevil-infested palms. We outline how such developments could lead to new control strategies and early detection tools.
棕榈象甲属的物种是原生、观赏和农业棕榈物种的破坏性害虫。在这 10 种已被识别的物种中，有两种危害最大的物种， 和 ，它们都已经扩散到了它们的原生范围之外，而且这两种也是研究最多的物种。由于其在全球范围内的传播更广，并且对中东的可食用枣椰产业造成了更大的破坏，因此 受到了更多的研究关注。综合虫害管理计划利用聚集信息素来诱捕害虫，清除受感染的棕榈树，并使用杀虫剂。然而，象甲的防治成本很高，对杀虫剂产生抗药性的问题也很棘手，而且由于早期发现虫害较为困难，项目的效果可能会受到影响。 的基因组已经被测序，而组学研究正在深入了解信息素通讯以及受象甲侵害的棕榈树挥发物和代谢物图谱的变化。我们概述了这些发展如何可能带来新的控制策略和早期检测工具。
