“…Links have been established between tooth geometry and angle of attack, distance, obliqueness, etc., and the effects of these parameters and the forces required to cut natural materials. Research on the basic structure of insect mouthparts, type of jaw, geometry, hardness and elemental content can help solve problems such as the coating of cutting tools or more efficient cutting designs [18]. Thus, several investigations have analyzed the geometric characteristics and shapes of different insect mouthparts to enhance the performance and design of bionic cutting tools.…”

Research Highlights: The novelty of this study is the deep analysis of the morphologic, geometric and mechanical performance of longhorn beetle larvae mouthparts. Furthermore, a metal nano identification of jaw reinforced parts was made. Background and Objectives: Analysis of insect mechanical properties has shown an important application in the develop of bionic technologies such as new materials, industrial machines and structural concepts. This study aims to determine the mechanical and geometric properties of longhorn beetle (Stromatium unicolor Olivier 1795) larvae mouthparts to improve the development of innovative cutting tools. In addition, this study obtains a nano identification of metals in the cuticle of the mouthparts, which will enable the development of new nontoxic and sustainable preservation agents against xylophagous insects based on nanoparticles. Materials and Methods: five third-larval-stage samples of Stromatium unicolor were used to study its mandible morphologic, geometric and mechanical properties. To this end, mouthparts were analyzed by several microscopic techniques using a scanning electron microscope, a stereomicroscope and an optical microscope. Composition analysis was performed using with two Analytical-Inca X-ray detectors, dispersive energy spectroscopy and dispersive wavelength spectroscopy. Results: The main geometric parameters of the insect jaw are the edge angle (β = 77.3°), maximum path depth of the insect (120 μm), length (800 µm) and mouthpart movement, which were identified and measured. The chemical analysis results of the jaw tissues shows the presence of zinc and manganese. Conclusions: The geometry and angles of the mouthparts can be applied in the fabrication of bionic self-sharpening cutting tools. Molecular compounds that form the reinforcing elements in the jaws can be used to develop wood preservatives based on nanometals and metal absorption and metabolism inhibitors.

The house longhorn beetle, Hylotrupes bajulus L., is a recognized wood pest with larvae capable of infesting and damaging various wood species. The larvae’s wood-cutting capability is attributed to the metal-reinforced chitin in their mandibles, which provides enhanced mechanical strength. This reinforcement is due to the presence of metal ions such as zinc (Zn) and manganese (Mn) bound to the chitin structure. The present study investigates the potential of diethylenetriaminepentaacetic acid (DTPA), a chelating agent, to sequester these crucial metal ions thereby affecting the larvae’s feeding capability. Wood samples treated with varying doses of DTPA showed significant larval mortality, with a 100% rate at a dose of 6 g/l. Electron microscopic analyses of deceased larvae revealed an absence of Zn in their mandibles, suggesting that DTPA effectively reduces its bioavailability, hindering mandible strengthening. The toxicity profile of DTPA is lower compared to many traditional wood treatments, indicating a potential for reduced environmental impact. However, the full spectrum of DTPA’s preservation capabilities and its interactions with other organisms require further investigation.
