Genomic signatures of evolutionary transitions from solitary to group living
For bees, many roads lead to social harmony Eusociality, where workers sacrifice their reproductive rights to support the colony, has evolved repeatedly and represents the most evolved form of social… Expand

Osmia lignaria is a solitary bee that over-winters as a fully eclosed, cocooned, unfed adult. Our objective is to understand the effect of wintering temperature on diapause maintenance and… Expand
Effect of pre-wintering and wintering temperature regimes on weight loss, survival, and emergence time in the mason bee Osmia cornuta (Hymenoptera: Megachilidae)
Osmia cornuta adults require exposure to wintering temperatures followed by incubation in the spring to emerge. We studied winter survival, weight loss, emergence time, and post-emergence longevity… Expand
Timing of eclosion affects diapause development, fat body consumption and longevity in Osmia lignaria, a univoltine, adult-wintering solitary bee.
Most insects from temperate areas enter diapause ahead of winter. Species diapausing in a feeding stage and accumulating metabolic reserves during permissive pre-wintering conditions are expected to… Expand
Development and Emergence of the Orchard Pollinator Osmia lignaria (Hymenoptera: Megachilidae)
Abstract The solitary bee Osmia lignaria Say has been developed as an orchard pollinator in the western United States. Immatures develop through the spring and summer. By late summer, bees become… Expand
Developing and establishing bee species as crop pollinators: the example of Osmia spp. (Hymenoptera: Megachilidae) and fruit trees
Abstract The development of a bee species as a new crop pollinator starts with the identification of a pollination-limited crop production deficit and the selection of one or more candidate… Expand
Management of Osmia lignaria (Hymenoptera: Megachilidae) Populations for Almond Pollination: Methods to Advance Bee Emergence
Abstract The objective of this study was to find one or more rearing methods that would allow us to release Osmia lignaria Say populations from natal nests to pollinate February-flowering almonds,… Expand
Temporal variation in overwintering gene expression and respiration in the solitary bee Megachile rotundata.
Partial clones of Megachile rotundata HSP90, HSP70, HSC70 and actin were developed by RT-PCR. These clones were used to generate probes to screen for the expression of their respective transcripts in… Expand
