Abstract

Platycorynus peregrinus (Herbst, 1783) is a leaf beetle of agricultural importance, yet its genetic diversity and population structure remain poorly understood. We analyzed mitochondrial cytochrome c oxidase subunit I (COI) sequences from 147 individuals across 19 populations in Thailand. Forty-five haplotypes were identified, showing high haplotype diversity (0.942) and moderate nucleotide diversity (0.00562). Significant genetic differentiation (Φ_ST = 0.0000-0.7857) was strongly associated with geographical distance, and this population structure was further supported by AMOVA (F_CT = 0.21925, p < 0.001). Neutrality tests and mismatch distribution analyses revealed signals of population expansion, alongside evidence of localized differentiation. The substantial genetic variability observed suggests high dispersal ability and possible cryptic lineages. These insights not only advance understanding of the evolutionary dynamics of P. peregrinus but also provide valuable guidance for developing sustainable pest management strategies.

泰国叶甲虫（Platycorynus peregrinus, Herbst, 1783）的遗传多样性、遗传结构和种群历史（鞘翅目：金甲科）。

Platycorynus peregrinus （Herbst, 1783）是一种具有重要农业意义的叶甲虫，但其遗传多样性和种群结构尚不清楚。我们分析了来自泰国19个人群147个个体的线粒体细胞色素c氧化酶亚基I （COI）序列。共鉴定出45个单倍型，单倍型多样性高（0.942），核苷酸多样性中等（0.00562）。显著的遗传分化（ΦST = 0.000 -0.7857）与地理距离密切相关，AMOVA进一步支持了这一群体结构（FCT = 0.21925, p < 0.001）。中性检验和错配分布分析揭示了种群扩张的信号，以及局部分化的证据。观察到的大量遗传变异性表明高分散能力和可能的隐谱系。这些发现不仅促进了对远山假蝇进化动力学的认识，而且为制定可持续的有害生物管理策略提供了有价值的指导。

期刊介绍： Biology (ISSN 2079-7737) is an international, peer-reviewed, quick-refereeing open access journal of Biological Science published by MDPI online. It publishes reviews, research papers and communications in all areas of biology and at the interface of related disciplines. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
