species (Lepidoptera, Lasiocampidae), are the most serious phytophagous pests of coniferous forests worldwide. feed intensively on needles, leading to considerable economic loss and ecological damage. Notably, the outbreak of is a somewhat periodic pattern, and those outbreaks cause rapid and large-scale destruction of pine forests, with those forests observed to look like "Fire without smoke". Sex pheromones play an important role during insect mating and reproduction, and there has been extensive research into the pheromone of . The pheromone components of several have been identified, and functions of two most important pheromone recognition genes, pheromone-binding proteins (PBPs) and pheromone receptors (PRs), were clarified. The evolution of PBP gene sequences is in good agreement with the trends in structural changes of the sex pheromone components in several species, and it is interesting that PRs of spp. occupy a novel lineage of PRs tuned to Type I pheromones in Lepidoptera. We present the current state of research into the sex pheromone of these important forest pests and highlight the emerging topics, to clarify future urgent work into .
[该昆虫的学名（鳞翅目，枯叶蛾科）]是全球针叶林最严重的植食性害虫。它们大量取食针叶，导致可观的经济损失和生态破坏。值得注意的是，[该昆虫的学名]的爆发呈一定的周期性模式，这些爆发会对松林造成迅速且大规模的破坏，这些森林看起来就像“无烟之火”。性信息素在昆虫交配和繁殖过程中起着重要作用，并且对[该昆虫的学名]的性信息素已有广泛研究。已鉴定出几种[该昆虫的学名]的性信息素成分，并且阐明了两个最重要的性信息素识别基因，即性信息素结合蛋白（PBPs）和性信息素受体（PRs）的功能。PBP基因序列的进化与几种[该昆虫的学名]物种中性信息素成分的结构变化趋势高度一致，有趣的是，[该昆虫的学名]属的PRs在鳞翅目中占据了一个新的、针对I型性信息素的PRs谱系。我们介绍了对这些重要森林害虫性信息素的研究现状，并突出了新出现的主题，以阐明未来针对[该昆虫的学名]的紧迫工作。
