partial cytochrome b sequences for six hymenoptera of the eastern united states.	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 si ...	2001	11948223
visitation by wild and managed bees (hymenoptera: apoidea) to eastern u.s. native plants for use in conservation programs.	addition of floral resources to agricultural field margins has been shown to increase abundance of beneficial insects in crop fields, but most plants recommended for this use are non-native annuals. native perennial plants with different bloom periods can provide floral resources for bees throughout the growing season for use in pollinator conservation projects. to identify the most suitable plants for this use, we examined the relative attractiveness to wild and managed bees of 43 eastern u.s. ...	2008	18559176
commensal nematodes in the glands, genitalia, and brood cells of bees (apoidea).	seven species of bees from the eastern united states, representing four families in the apoidea, were dissected and examined for nematode associates. dufour's glands in females of halictus ligatus, augochlora pura mosieri, and augochlorella gratiosa (halictidae) from florida were infested with dauer juveniles of aduncospiculum halicti (diplogasteridae). the dufour's glands of colletes thoracicus (colletidae) females from maryland were infested with dauer juveniles of a new species of koerneria s ...	1990	19287704
