Now, scientists have announced a plan to map the genomes of at least 100 of these species, representing each of the major bee taxonomic groups in the U.S. The project “will help researchers answer the big questions like what genetic differences make some bee species more vulnerable to climate change or whether a bee species is likely to be more susceptible to a pesticide,” entomologist Jay Evans with the ARS Bee Research Laboratory in B…
