角质层外骨骼在促进昆虫进化成功中起着关键作用。自上世纪中叶以来，外骨骼的许多不同的生物力学特性已经被研究，总是利用当时可用的最先进的科学方法。到目前为止，关于角质层的生物力学特性的信息似乎和测量它们的方法一样多种多样。因此，昆虫角质层通常被认为是所有生物材料中最复杂和最多样化的生物力学特性。然而，尚不清楚先前研究中使用的各自的测量方法和样本处理在支持这一主张方面起到了什么作用。本文综述了用于研究昆虫外骨骼生物力学性能的检测技术，并讨论了它们在描述角质层等复杂材料的性能方面各自的优缺点。我们对当前数据的荟萃分析证实了各自的测量方法、样品处理和身体部位对所获得的机械性能的显著影响。根据我们的研究结果，我们指出了研究的差距，并指出了在未来的昆虫角质层研究中应该考虑的重要因素。
The cuticle exoskeleton plays a key role in facilitating the evolutionary success of insects. Since the mid of the last century, many different biomechanical properties of exoskeletons have been investigated, always utilizing the most sophisticated scientific methods available at the time. So far, information on the biomechanical properties of cuticle seems to be as diverse as the methods used to measure them. As a consequence, insect cuticle is often considered to exhibit the most complex and diverse biomechanical properties of any biological material. However, it remains unclear which role the respective measurement methods and sample treatments used in previous studies play in supporting this claim. This review provides a broad overview of examination techniques used to study biomechanical properties of insect exoskeletons and discusses their respective advantages and disadvantages in describing the properties of a complex material such as cuticle. Our meta-analysis of the present data confirms significant effects of the respective measurement methods, sample treatments and body parts on the obtained mechanical properties. Based on our findings, we highlight research gaps and point out important factors which should be taken into account in future studies on insect cuticle.
