Abstract

Honey bees play a crucial role as pollinators in balancing the elements of the floral and faunal ecosystems. In honey bee colonies, male bees (drones) are crucial for population sustainability, offspring production, and the maintenance of phenotypic and genotypic variation. However, male bees have often been overlooked in apicultural research. The viability and potency of drone sperm production are critical factors influencing the health of queen bees and their subsequent progeny. In conclusion, factors that affect drone viability will also affect the progeny within colonies. This study highlights several key characteristics, such as semen volume, sperm concentration, viability, transfer dynamics, and testicular morphology, to assess drone fertility, which would provide basic facts in assessing sperm potency and ability to fertilize the female while undergoing newer breeding methods in bees. An overview of the genes responsible for spermatogenesis in drone bees, along with the roles of metabolic constituents like glandular proteins, is necessary to understand genetic diversity in bee populations. This review underscores the necessity of drone fertility as a key determinant of colony cohesion, evolutionary fitness, and adaptive capacity of honey bee populations in changing environmental contexts.
