Blue orchard bees (BOBs) are increasingly being used to pollinate California fruit and nut crops. Still, they are often trapped annually in the wildlands of Utah, Washington, and California rather than propagated where they are used as pollinators. This makes it critical to understand the adaptability of populations to new and warming environments because BOBs are currently moved to areas with temperatures warmer than within natal ranges. Local climate adaptation may be seen in future generations when the bees remain in crops locally. Compared to first generation bees whose parents were newly imported, second and third generations may have higher survival and developmental phenology that better aligns with the timing of crop bloom. However, the potential negative impact of warming temperatures on local and transported BOB populations could be decreased bee fitness and pollination efficacy. We found that population location did change pollination efficacy; those populations closer to CA ambient temperatures were more effective at pollination. Additionally, development timing, body size and emergence rates were all effected by original population sources. However, emergence timing was more aligned by generation rather than the population in year two. Therefore, development timing was based on environmental pressure rather than on genetics.
