	abstract = {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 pollinator transformed the alfalfa seed industry in North America, tripling seed production. The most common ALCB management practice is the loose cell system, in which cocooned bees are removed from nesting cavities for cleaning and storage. Traits of ALCBs that favored their commercialization include gregarious nesting; use of leaves for lining nests; ready acceptance of affordable, mass-produced nesting materials; alfalfa pollination efficacy; and emergence synchrony with alfalfa bloom. The ALCB became a commercial success because much of its natural history was understood, targeted research was pursued, and producer ingenuity was encouraged. The ALCB presents a model system for commercializing other solitary bees and for advancing new testable hypotheses in diverse biological disciplines},

	abstract = {As with most solitary bees, larvae of the alfalfa leaf-cutting bee, Megachile rotundata Fab., eat a diet blended from pollen and nectar of unknown proportions. In this study, we developed protocols to isolate and quantify sugars from larval provision masses. The method removed free amino acids that leach from pollen and confound chromatography, but without autohydrolyzing sucrose. Pollen sugars were a negligible fraction of provision mass sugars. Glucose and fructose constituted about half of the provision fresh weight. Sucrose in alfalfa pollen and nectar is absent from the provision, presumably enzymatically hydrolyzed to glucose and fructose in the provision. Provision masses are composed of two to three times more floral equivalents in pollen than nectar. Female M. rotundata, and other solitary bees with pasty provisions, gather proportionally more pollen than nectar compared with the resource needs of colonies of social honeybees and bumblebees},
