Forestry is raising concern about the outbreaks of European spruce bark beetle, Ips typographus, causing extensive damage to the spruce forest and timber values. Precise monitoring of these beetles is a necessary step towards preventing outbreaks. Current commercial monitoring methods are catch‐based and lack in both temporal and spatial resolution. In this work, light scattering from beetles is characterized, and the feasibility of entomological lidar as a tool for long‐term monitoring of bark beetles is explored. Laboratory optical properties, wing thickness, and wingbeat frequency of bark beetles are reported, and these parameters can infer target identity in lidar data. Lidar results from a Swedish forest with controlled bark beetle release event are presented. The capability of lidar to simultaneously monitor both insects and a pheromone plume mixed with chemical smoke governing the dispersal of many insects is demonstrated. In conclusion, entomological lidar is a promising tool for monitoring bark beetles.

树皮甲虫作为激光雷达的目标和光子监视的前景

林业引起人们对欧洲云杉树皮甲虫Ips typographus爆发的担忧，对云杉的森林和木材价值造成广泛的破坏。准确监测这些甲虫是预防疾病暴发的必要步骤。当前的商业监测方法是基于捕获的，并且在时间和空间分辨率上都缺乏。在这项工作中，对甲虫的光散射进行了表征，并探讨了昆虫激光雷达作为对树皮甲虫进行长期监测的工具的可行性。报告了树皮甲虫的实验室光学特性，机翼厚度和机翼拍频，这些参数可以推断激光雷达数据中的目标身份。呈现了瑞典森林中的激光雷达结果，其中控制了树皮甲虫的释放事件。证明了激光雷达能够同时监视昆虫和与化学烟雾混合的信息素羽，该化学烟雾控制着许多昆虫的扩散。
