Do Varroa mites preferentially infest specific age groups of bees?

• A. Yes, only older bees
• B. No, they infest all ages equally
• C. Yes, they prefer drone brood and older bees
• D. No, they avoid old bees

Answer: (C)

Varroa mites have a distinct preference for certain age groups of bees, particularly drone brood and older bees. This preference stems from the fact that Varroa mites thrive in the brood cells where developing bees, especially drones, are present. Drones provide an ideal environment for the mites to reproduce, as their longer development time compared to worker bees allows for more opportunity for the mites to multiply. Additionally, adult bees, especially older ones, are more susceptible to mite infestation because they spend more time outside the hive, foraging and coming into contact with other infested bees. The lifecycle of the Varroa mite is closely linked to the development of its bee hosts, making drone brood an optimal target as well as younger bees. Understanding this preference is crucial for beekeepers as it informs monitoring and management strategies. It highlights the importance of regular inspections and interventions, especially during times when drone brood is present, to control mite populations effectively. Recognizing the dynamics between Varroa mites and different bee age groups enables better management of bee health and colony strength.
