Correct species identification is the cornerstone of all scientific studies that involve insects. Alongside traditional morphological identification techniques, molecular identification based on the characterization and analysis of specific mitochondrial or nuclear gene regions is becoming commonplace. Despite the good results that can be achieved, DNA extraction usually involves invasive techniques that lead to the partial or total destruction of specimens. In this work, a non-invasive DNA extraction technique is described. The technique was tested on the abdomens of dry-preserved Sarcophagidae (Diptera) specimens collected between 1889 and 2015. This allowed for the correct identification of species without impairing diagnostic morphological structures useful for further studies.
正确的物种鉴定是所有涉及昆虫的科学研究的基石。除了传统的形态学鉴定技术外,基于特定线粒体或核基因区域的特征化和分析的分子鉴定正变得越来越普遍。尽管可以取得良好的结果,但DNA提取通常涉及侵入性技术,这会导致标本部分或全部被破坏。在这项工作中,描述了一种非侵入性DNA提取技术。该技术在1889年至2015年间收集的干制麻蝇科(双翅目)标本的腹部上进行了测试。这使得能够正确鉴定物种,而不会损害对进一步研究有用的诊断形态结构。
