Achelura yunnanensis is a destructive pest of forests, causing substantial damage on tree growth and severe economic losses. Additionally, as a daytime-active moth, this species also holds important scientific value for investigating the genetic mechanisms governing day-night activity patterns of Lepidoptera. To facilitate effective pest control and deepen our understanding of the diurnal behavior's genetic basis of moths, genomic data for this species are crucial. In this study, we present a chromosome-level reference genome of A. yunnanensis (368.15 Mb in 32 chromosomes; scaffold N50 = 12.61 Mb; BUSCO completeness = 98.0%). Genome annotation shows that the new assembly comprises 37.10% (136.55 Mb) repetitive elements, 1,828 non-coding RNAs, and 15,523 protein-coding genes. Genes involved in lipid metabolism and xenobiotics biodegradation and metabolism, such as cytochrome P450 families, experienced significant expansion in the A. yunnanensis genome. The chromosome-level genome of A. yunnanensis provides a valuable genomic resource for devising novel pest control strategies, and will also help to study the genetic mechanism of the shift of diurnal behavior in Lepidoptera.
云南盘蜡蝉是一种对森林具有破坏性的害虫，会对树木生长造成严重损害，并导致严重的经济损失。此外，作为一种日间活动的飞蛾，该物种对于研究鳞翅目昼夜活动模式的遗传机制也具有重要的科学价值。为了实现有效的害虫防治，并深入了解飞蛾昼间行为的遗传基础，该物种的基因组数据至关重要。在本研究中，我们提供了云南盘蜡蝉的染色体水平参考基因组（大小为 368.15Mb，包含 32 条染色体；支架 N50=12.61Mb；BUSCO 完整性=98.0%）。基因组注释表明，新组装的基因组包含 37.10%（136.55Mb）的重复序列、1828 种非编码 RNA 和 15523 个蛋白质编码基因。涉及脂质代谢和外来化合物生物降解和代谢的基因，如细胞色素 P450 家族，在云南盘蜡蝉基因组中经历了显著扩张。云南盘蜡蝉的染色体水平基因组为设计新型害虫防治策略提供了宝贵的基因组资源，也将有助于研究鳞翅目昼间行为转变的遗传机制。
