Abstract

This study presents the first record of Miyalachnus sorini Kanturski & Lee, 2024 (Aphididae: Lachninae) in South Korea, thereby extending its known distribution beyond Japan and identifying a new host plant, Prunus sargentii (Rosaceae). We describe diagnostic morphological traits across multiple life stages and compare them with those of Japanese populations. Comparative analyses with Japanese populations demonstrated consistent morphological differentiation, notably elevated ratios of the ultimate rostral segment to antennal segments across multiple morphs in the Korean population, indicating potential ecological adaptation. DNA barcoding using the mitochondrial cytochrome c oxidase I gene revealed low intraspecific divergence (average 0.2%) and interspecific divergence (average 10.5%) between Miyalachnus sp. and M. sorini. Haplotype analysis was performed to investigate the relationship between host plants and cryptic genetic diversity. These findings enhance our understanding of the morphological and genetic diversity of M. sorini and underscore the importance of monitoring its spread for informed pest management strategies.

韩国樱桃树寄主植物关联及隐遗传多样性揭示（蚜科：蚜科）

本研究提出了Miyalachnus sorini Kanturski & Lee， 2024在韩国的第一个记录（蚜虫科：Lachninae），从而将其已知分布扩展到日本以外，并确定了一个新的寄主植物Prunus sargentii（玫瑰科）。我们描述了诊断形态特征跨越多个生命阶段，并与那些日本人口进行比较。与日本种群的比较分析显示了一致的形态分化，特别是韩国种群中多个变种的最终吻端节与触角节的比例升高，表明潜在的生态适应。利用线粒体细胞色素c氧化酶I基因进行的DNA条形码分析显示，Miyalachnus sp.和M. sorini的种内差异（平均为0.2%）和种间差异（平均为10.5%）较低。采用单倍型分析研究寄主植物与隐型遗传多样性的关系。这些发现增强了我们对sorini的形态和遗传多样性的理解，并强调了监测其传播对知情虫害管理策略的重要性。

期刊介绍： Established in 1910, the internationally recognised Bulletin of Entomological Research aims to further global knowledge of entomology through the generalisation of research findings rather than providing more entomological exceptions. The Bulletin publishes high quality and original research papers, ''critiques'' and review articles concerning insects or other arthropods of economic importance in agriculture, forestry, stored products, biological control, medicine, animal health and natural resource management. The scope of papers addresses the biology, ecology, behaviour, physiology and systematics of individuals and populations, with a particular emphasis upon the major current and emerging pests of agriculture, horticulture and forestry, and vectors of human and animal diseases. This includes the interactions between species (plants, hosts for parasites, natural enemies and whole communities), novel methodological developments, including molecular biology, in an applied context. The Bulletin does not publish the results of pesticide testing or traditional taxonomic revisions.
