Impact/Purpose:
Bumble bee population declines over the last decade have stimulated strong interest in determining causative factors and necessary conservation measures. In this review we assess existing literature on the diverse role of males within bumble bee nests and their importance to queen health and fitness, as well as overall nest success.
Description:
Bumble bee population declines over the last decade have stimulated strong interest in determining causative factors and necessary conservation measures. Research attention has largely been directed toward bumble bee worker and queen health and their contributions to population stability, while male bees (i.e., drones) have typically been overlooked for their role in influencing colony fitness and longevity. In this review we assess existing literature on the diverse role of males within bumble bee nests and their importance to queen health and fitness, as well as overall nest success. The implications of reproductive measures including sperm transfer, mating behavior, mating plugs, and male immunity, among other topics are examined. Overall, bumble bee males are found to drive colony function in a unique manner. Current knowledge gaps pertaining to the role of males are discussed. We highlight the importance of drones to queen success and colony fitness in many ways, and suggest future research exploring impacts of this often-neglected caste.
