The alfalfa leafcutting bee, Megachile rotundata: the world's most intensively managed solitary bee.
The alfalfa leafcutting bee (ALCB), Megachile rotundata F. (Megachildae), was accidentally introduced into the United States by the 1940s. Nest management of this Eurasian nonsocial pollinatorExpand
The long summer: pre-wintering temperatures affect metabolic expenditure and winter survival in a solitary bee.
The impact of climate change on insect populations depends on specific life cycle traits and physiological adaptations. The solitary bee Osmia lignaria winters as a pre-emergent adult, and requires aExpand
Pesticide Exposure Assessment Paradigm for Solitary Bees
Abstract Current pesticide risk assessment for bees relies on a single (social) species, the western honey bee, Apis mellifera L. (Hymenoptera: Apidae). However, most of the >20,000 bee speciesExpand
Integrated Crop Pollination: Combining strategies to ensure stable and sustainable yields of pollination-dependent crops
Abstract Our growing human population will be increasingly dependent on bees and other pollinators that provide the essential delivery of pollen to crop flowers during bloom. Within the context ofExpand
Effects of Fungicide and Adjuvant Sprays on Nesting Behavior in Two Managed Solitary Bees, Osmia lignaria and Megachile rotundata
There is a growing body of empirical evidence showing that wild and managed bees are negatively impacted by various pesticides that are applied in agroecosystems around the world. The lethal andExpand
Influence of Guidelines and Passageways on Tunneling Behavior of Reticulitermes flavipes (Kollar) and R. virginicus (Banks) (Isoptera: Rhinotermitidae)
Tunneling behavior of laboratory-maintained cultures of Reticulitermes flavipes (Kollar) and R. virginicus (Banks) was examined to determine (1) if the termites build tunnels along preexisting wiresExpand
Olfactory Response of Megachilid Bees, Osmia lignaria, Megachile rotundata, and M. pugnata, to Individual Cues from Old Nest Cavities
Abstract The megachilid bees Osmia lignaria Say, Megachile rotundata (F.), and M. pugnata Say were tested for attraction to various components associated with their old nest cavities, or chemicalExpand
The Proboscis Extension Reflex Not Elicited in Megachilid Bees
A honey bee will reflexively extend its proboscis in response to antennal stimulation with sucrose solution (Bitterman et al, 1983). For decades the proboscis extension reflex (PER) of honey beesExpand
