               Background
               Honey bee males (drones) exhibit life histories that enable a high potential for pre- or post-copulatory sperm competition. With a numerical sex ratio of ∼11,000 drones for every queen, they patrol flyways and congregate aerially to mate on the wing. However, colonies and in fact drones themselves may benefit from a relative lack of competition, as queens are highly polyandrous, and colonies have an adaptive advantage when headed by queens that are multiply mated. Previous research has shown that larger drones are more likely to be found at drone congregation areas, more likely to mate successfully, and obtain a higher paternity share. However, the reproductive quality and size of drones varies widely within and among colonies, suggesting adaptive maintenance of drone quality variation at different levels of selection.

This is particularly evident when beekeepers create new colonies from packages, where many queens are immediately rejected or replaced after only a few weeks. Relatively little is known about the mechanisms that trigger supersedure in honey bees, although previous studies have shown a strong link with open brood suggesting that brood ester pheromone (BEP) may be involved. We installed new packages into hive equipment with either no treatment (Control), exposure to BEP during package transport and for the first 10 days after installation (BEP), or one frame of open brood (Brood). We found that over the course of the 12-week experiment, Control colonies grew the least, Brood colonies started stronger but leveled off similar to Control colonies, and BEP colonies grew slowly initially but continued positive growth through the end of the experiment. Moreover, we found a highly significant effect of treatment on Outcome—whether the initial queens were immediately Rejected (within 5 weeks), Superseded (after 5 weeks), or Accepted, with Brood, BEP, and Control colonies having 86.7%, 53.3%, and 33.3% acceptance, respectively. Finally, we found that the open-brood:adult-bees ratio significantly diverged 3 weeks prior to queen replacement between accepting and replacing colonies. We suggest that while BEP alone is insufficient to deter premature supersedure, there are clear benefits to queen longevity and package-installation success when establishing new colonies with frames of young brood.}, number={2}, journal={JOURNAL OF APICULTURAL RESEARCH}, author={Tarpy, David R. and Talley, Eric and Metz, Bradley N.}, year={2020}, month={Dec}, pages={220–228} }

Much of the reproductive quality of the queen, though, is a function of the mating success and quality of the drones (males). Many environmental factors can negatively impact drone semen quality, but little is known about factors that impact the drones’ ability to successfully mate and deliver that semen, or how widely drones vary. In our study, we observed the daily variation in honey bee drone reproductive quality over time, along with a number of morphological traits. Drones were reared in cages in bank colonies, and 20 individuals were dissected and measured daily. The number of viable spermatozoa in the seminal vesicles was zero at emergence and reached an average maximum of 7.39 ± 0.19 million around 20 days of life. Decline in spermatozoa count occurred after day 30, though viability was constant throughout life, when controlling for count. Older drones had smaller wet weights, head widths, and wing lengths. We predict that this is likely due to sampling bias due to a differential lifespan among larger, more reproductively developed drones. Our study shows that drones are more highly variable than previously suggested and that they have a significant variation in reproductive physiology as a function of age.}, number={1}, journal={INSECTS}, author={Metz, Bradley N. and Tarpy, David R.}, year={2019}, month={Jan} }
