摘要
2014 年,南非姆普马兰加省首次发现蓝莓芽螨(Acalitus vaccinii,Acari: Trombidformes: Eriophyidae),对栽培蓝莓造成了重大损害。这是在其原产地北美洲以外首次发现这种害虫。然而,当时对它的分类学描述缺乏关键细节,遗漏了对轻松准确识别非常重要的特征和生命阶段。我们采用综合分类方法,结合相衬光学显微镜、低温扫描电镜和 DNA 条形码数据,利用南非标本修订了对 A. vaccinii 的描述。以前的描述中没有包括但在此报告的其他特征是 h1(附属)刚毛、腿 I 和 II u'(中轴)刚毛以及腿 II bv(股)刚毛。报告中包括对所有生命阶段的详细描述和测量结果,以及对形态变异和生物学特性的讨论。还提供了两个共同条形码区域(核和线粒体)的 DNA 序列,以进一步帮助识别。此外,还提供了存在于越橘上的所有已知麦角螨种类的检索表。
Revised description of the blueberry bud mite, Acalitus vaccinii (Acari: Trombidiformes: Eriophyidae), and a key to all Eriophyoidea on Vaccinium
In 2014 the blueberry bud mite, Acalitus vaccinii (Acari: Trombidformes: Eriophyidae), was detected in the Mpumalanga province of South Africa for the first time causing significant damage to cultivated blueberries. This was the first detection of this pest outside of North America, to which it is native. However, its taxonomic description at that time lacked critical detail and omitted characters and life stages important for easy and accurate identification. Using an integrative taxonomic approach, we combined phase contrast light microscopy with low-temperature SEM and DNA barcoding data to revise the description of A. vaccinii using South African specimens. Additional characters not included in previous descriptions but reported here are the h1 (accessory) setae, leg I & II u’ (mesal) setae, and leg II bv (femoral) setae. Detailed descriptions and measurements of all life stages are included, along with a discussion of morphological variation and biology. Two DNA sequences of common barcode regions (nuclear and mitochondrial) are provided to further aid in identification. In addition, a key to all known species of eriophyoid mites present on Vaccinium is provided.
期刊介绍:
African Entomology (ISSN 1021-3589 – print / 2224-8854 – online) replaced the old Journal of the Entomological Society of Southern Africa in 1993. A single volume consisting of two issues (March and September) is published annually. The journal is indexed in all major abstracting journals
African Entomology is a peer reviewed scientific journal that publishes original research articles and short communications on all aspects of entomology, with an emphasis on the advancement of entomology on the African continent.
