Species of the click-beetle genus Eschscholtz are economically important crop pests distributed mainly in the Northern Hemisphere. They can inflict considerable damage on various field crops. Therefore, the detection, monitoring, and control of include the adult trapping using species-specific sex pheromones, which is a critical component of pest research. To obtain a better understanding of the detailed antennal morphology as background information for subsequent chemical ecology research, we conducted a scanning electron microscopy study of the antennal sensilla of both sexes in 10 European species. We identified 16 different sensilla in , belonging to six main types: sensilla chaetica (subtypes C1 and C2), sensilla trichodea, sensilla basiconica (subtypes B1-B9), dome-shaped sensilla (subtypes D1 and D2), sensilla campaniformia, and Böhm sensilla. We discuss their possible functions and compare the sensilla of with those of other Elateridae in order to consolidate the sensillum nomenclature in this family. Additionally, our study reveals the remarkable interspecific variability in sensillar equipment of and identifies several characters of potential importance for future use in systematic studies. The present study provides a strong preliminary framework for subsequent research on the antennal morphology of this crop pest on a wider scale.
叩头虫属埃氏叩甲的物种是具有重要经济意义的作物害虫，主要分布在北半球。它们会对各种大田作物造成相当大的损害。因此，对其进行检测、监测和控制，包括使用物种特异性性信息素诱捕成虫，这是害虫研究的关键组成部分。为了更深入了解详细的触角形态，作为后续化学生态学研究的背景信息，我们对10种欧洲物种的两性触角感器进行了扫描电子显微镜研究。我们在其中鉴定出16种不同的感器，属于六种主要类型：毛形感器（亚型C1和C2）、刚毛形感器、锥形感器（亚型B1 - B9）、圆顶形感器（亚型D1和D2）、钟形感器和博氏感器。我们讨论了它们可能的功能，并将埃氏叩甲的感器与其他叩甲科昆虫的感器进行比较，以巩固该科的感器命名法。此外，我们的研究揭示了埃氏叩甲感器装备的显著种间变异性，并确定了几个在未来系统研究中可能具有重要意义的特征。本研究为后续更广泛地研究这种作物害虫的触角形态提供了一个强有力的初步框架。
