棉铃虫Helicoverpa armigera是美洲大陆的一种检疫性农业害虫。历史上H。armigera被认为在大约150万到200万年前殖民了美洲大陆，导致了现在的H。美洲大陆的玉米种群。相对较新的物种分化历史在H. zea和H.在实验室条件下进行。尽管H.虽然美洲棉铃虫已进入北美，但据信该害虫物种在两大洲都没有成功地建立重要种群。本研究通过线粒体DNA（mtDNA）细胞色素氧化酶I（COI）和细胞色素B（Cyt B）部分基因序列的测定，为该菌最近的成功入侵提供了分子证据。在巴西马托格罗索州的两个地点（Primavera do Leste和佩德拉普雷塔）发现了这种个体。在巴西血吸虫中检测到mtDNA COI和Cyt B单倍型。棉铃虫个体在整个旧大陆都很常见，因此无法确定其创始种群。结合这两个部分mtDNA基因序列表明，至少有两个matrilines存在于巴西，而列入三个核DNA外显子引物内含子交叉（EPIC）标记确定了另外两个可能的matrilines在我们的样品。经济，生物安全，抗性管理，生态和进化的影响，这种入侵进行了讨论，在美洲目前的农业实践。
The highly polyphagous Old World cotton bollworm Helicoverpa armigera is a quarantine agricultural pest for the American continents. Historically H. armigera is thought to have colonised the American continents around 1.5 to 2 million years ago, leading to the current H. zea populations on the American continents. The relatively recent species divergence history is evident in mating compatibility between H. zea and H. armigera under laboratory conditions. Despite periodic interceptions of H. armigera into North America, this pest species is not believed to have successfully established significant populations on either continent. In this study, we provide molecular evidence via mitochondrial DNA (mtDNA) cytochrome oxidase I (COI) and cytochrome b (Cyt b) partial gene sequences for the successful recent incursion of H. armigera into the New World, with individuals being detected at two sites (Primavera do Leste, Pedra Preta) within the State of Mato Grosso in Brazil. The mtDNA COI and Cyt b haplotypes detected in the Brazilian H. armigera individuals are common throughout the Old World, thus precluding identification of the founder populations. Combining the two partial mtDNA gene sequences showed that at least two matrilines are present in Brazil, while the inclusion of three nuclear DNA Exon-Primed Intron-Crossing (EPIC) markers identified a further two possible matrilines in our samples. The economic, biosecurity, resistance management, ecological and evolutionary implications of this incursion are discussed in relation to the current agricultural practices in the Americas.
