| first detection of nosema ceranae, a microsporidian parasite of european honey bees (apis mellifera), in canada and central usa. | nosema ceranae is an emerging microsporidian parasite of european honey bees, apis mellifera, but its distribution is not well known. six nosema-positive samples (determined from light microscopy of spores) of adult worker bees from canada (two each from nova scotia, new brunswick, and prince edward island) and two from usa (minnesota) were tested to determine nosema species using previously-developed pcr primers of the 16s rrna gene. we detected for the first time n. ceranae in canada and centr ... | 2008 | 17897670 |

| flowering dynamics and pollinator visitation of oilseed echium (echium plantagineum). | echium (echium plantagineum l.) is an alternative oilseed crop in summer-wet temperate regions that provides floral resources to pollinators. its seed oil is rich in omega-3 fatty acids, such as stearidonic acid, which is desired highly by the cosmetic industry. seeds were sown in field plots over three years in western minnesota in spring (early-sown) or early summer (late-sown), and flower abundance, pollinator visitation, and seed yields were studied. initial flowering commenced 41 to 55 d af ... | 2014 | 25427071 |
