Partial cytochrome b sequences for six Hymenoptera of the Eastern United States

Abstract

Mitochondrial DNA (mtDNA) haplotypes have been commonly used to determine honeybee subspecies relationships. To see if these markers would also be useful for comparisons of other Hymenoptera, we collected workers of six local species: Vespa crabro, the European hornet; Bombus impatiens, a bumblebee; Vespula germanica, the German yellow jacket; Polistes fuscatus, a paper wasp; Halictus ligatus, an alkali bee; and an unspecified Megachile, a leafcutting bee. MtDNA was isolated and digested with six endonucleases (Aval, BgIII, EcoRI, HindIII, HinfI, Xbal). The digested DNA was electrophoresed and visualized on agarose gels with comparison to a standard fragment marker and similarly treated honeybee mtDNA. The fragments obtained were also purified and sequenced. Phylogenetic relationships between six wasp and bee species, Apis mellifera, and several other similar aculeate Hymenoptera were determined. Newly defined DNA sequences were posted to GenBank (AF281169-AF281174).
