  1. Nesting Biology of Osmia cornifrons: Implications for Population Management

    … hornfaced bee, Osmia cornifrons (Hymenoptera: Megachilidae) is a palearctic mason bee managed for the pollination of early season fruit crops such as apple and blueberry. Since its adoption as a managed pollinator in Japan during the 1940s, a large body of literature has amassed with the goal …

    … (Andrenidae, Apidae, Colletidae, Halictidae and Megachilidae). The bee community was characterized by three distinct periods of flight activity over the four years studied (early spring, late spring/early summer, and late summer). The number of bees collected in spring was significantly higher …

  3. Nesting aggregation as a Determinant of Brood Parasitism in Mason Bees (Osmia spp.)

    … bees (members of the genus Osmia; Hymenoptera: Megachilidae) are important pollinators for agricultural systems and are vulnerable to exploitation by brood parasites, such as kleptoparasitic wasps. High levels of nesting density have the potential to increase rates of brood parasitism by …

    … Osmia cornuta (Latreille, 1805) (Hymenoptera: Megachilidae), and the wasp Polistes dominula (Christ, 1791) (Hymenoptera: Vespidae). The field studies were preceded by a re-analysis of published data on wild bee communities in different cities around the world, which showed how highly urbanised …

  5. Wild bee responses to land use change: investigating the role of bee body size

    Land use change impacts biodiversity through many facets including an alteration of habitat and the resources required to sustain species and populations. Wild bees (Hymenoptera: Apoidea) are essential pollinators for many wild and cultivated flowering plants, and exhibit marked differences in life …
