Abstract

Population genetic analysis of mitochondrial DNA barcodes, comprised of a standard segment of the cytochrome c oxidase subunit I gene (COI or cox1), was conducted on Spoladea recurvalis (Fabricius), an important agricultural pest commonly referred to as the Hawaiian beet webworm. Results of genetic diversity analyses indicate significant population structure between samples mainly from Australia and nearby regions and those from North America, Africa, Europe, and Asia. Adults of the two groups are morphologically indistinguishable but are characterised by diagnostic barcode nucleotides and genetic diversity values. Factors possibly involved in driving genetic divergence in S. recurvalis in the Australian region are briefly discussed.

DNA条形码揭示了一种广泛分布的农业害虫——夏威夷甜菜网虫的种群结构。

利用细胞色素c氧化酶亚基I基因（COI或cox1）标准片段组成的线粒体DNA条形码，对夏威夷甜菜网虫（Spoladea recurvalis，简称Fabricius）进行了群体遗传分析。遗传多样性分析结果表明，主要来自澳大利亚及其附近地区的样本与来自北美、非洲、欧洲和亚洲的样本之间存在显著的群体结构。两组的成人在形态上难以区分，但其特征是诊断条形码核苷酸和遗传多样性值。简要讨论了在澳大利亚地区可能涉及的驱动S. recurvalis遗传分化的因素。

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.
