摘要

摘要夏威夷农业部在2018年和2019年截获的蚂蚁被确认为索氏蚁属,可能还有隐球菌,已提交给美国农业部医学、农业和兽医昆虫学农业研究服务中心,进口火蚁和家用昆虫研究单位,使用遗传和化学方法进行进一步的分类评估。2018年的样本包括1只工蚁,2019年的样本由3只工蚁组成。胸腔用于基因评估,胃用于毒液分析。从基因和化学分析中很容易确定,被拦截的蚂蚁不是隐球菌或里氏杆菌。将线粒体COX1基因序列与先前发表的索氏菌物种的数据进行比较。与2018年样本最匹配的是原产于该批货物(美国加利福尼亚州圣地亚哥)的梭梭。发现的2种主要生物碱具有双子花属植物群的特征。此外,生物碱的比例与梭梭的生物碱比例非常接近。因此,对2018年被截获的蚂蚁的生物碱分析与该蚂蚁是一名梭梭工蚁的遗传数据一致。2019年截获的COX1基因序列与双子花最接近。相应的毒液生物碱图谱也排除了隐球菌和毛滴虫的可能性。然而,1种主要生物碱是不寻常的(图2),通常只在微量中发现。我们认为,2019年的标本是双子星的一个不寻常的变种。

Genetic and Chemical Profiling of Solenopsis spp. (Hymenoptera: Formicidae) Intercepted in Hawaii
Summary Ants intercepted by the Hawaii Department of Agriculture in 2018 and 2019 identified as Solenopsis spp., and possibly S. invicta, were submitted to the United States Department of Agriculture-Agricultural Research Service-Center for Medical, Agricultural and Veterinary Entomology, Imported Fire Ant and Household Insects Research Unit for further taxonomic assessment using genetic and chemical methods. The 2018 sample consisted of 1 worker ant, and the 2019 sample consisted of 3 worker ants. Thoraces were used for genetic assessment and gasters were used for venom analyses. It was determined readily from genetic and chemical analyses that the intercepted ants were not S. invicta or S. richteri. Mitochondrial COX1 gene sequences were compared with previously published data from Solenopsis species. The closest match for the 2018 sample was S. xyloni, which is native to the shipment's origin (San Diego, California, USA). The 2 major alkaloids found were characteristic of the S. geminata species group. In addition, the alkaloid ratio closely matched that of S. xyloni. Therefore, the alkaloid analysis of the 2018 intercepted ant concurs with the genetic data that the ant was an S. xyloni worker. The COX1 gene sequences of the 2019 interceptions most closely matched S. geminata. The corresponding venom alkaloid profile also eliminated S. invicta and S. richteri as possibilities. However, 1 major alkaloid was unusual (Fig. 2) and normally is found only in trace amounts. We suggest the 2019 specimens are an unusual variant of S. geminata.

期刊介绍: Florida Entomologist is the official journal of the Florida Entomological Society. Volumes 1-3 were published under the name The Florida Buggist. The Florida Entomological Society still produces the traditionally printed version of Florida Entomologist, but you can also view, search, or print any article published since June 1917 by accessing online files. Web access is made possible by the Society’s electronic publication project begun in 1993
