Abstract

A strain of the alfalfa leafcutter bee, Megachile pacifica Panzer, that has produced less than 1% second-generation adults for 3 consecutive years was produced by selection against bivoltinism. The selection process also resulted in the production of bees that reproduced at a much higher rate than the unselected parent stock.
