Timing of diapause initiation and overwintering conditions alter gene expression profiles in Megachile rotundata

Lizzette D. Cambron-Kopco, George D. Yocum, Kathleen M. Yeater, Kendra J. Greenlee Abstract Within the United States and Canada, the primary pollinator of alfalfa is the alfalfa leafcutting bee (ALCB), Megachile rotundata.
