Beekeepers, have you considered the hidden dangers lurking within your hives? A new study by Courtney MacInnis and colleagues dives into the impacts of Nosema ceranae and Lotmaria passim, two globally prevalent honeybee gut parasites. These findings are vital for safeguarding the health and productivity of your colonies.



Key Findings from the Study:


  1. Dual Parasite Presence: Both Nosema ceranae and Lotmaria passim were found in honeybees, with L. passim being more common but less studied.


  2. Severity of Single Infections: Single infections by Nosema ceranae caused significant reductions in honeybee lifespan and heightened energetic stress compared to co-

    infections.


  3. Impact on Sucrose Responsiveness: Parasite-infected bees exhibited increased sucrose responsiveness, indicating hunger and energy depletion, which could impair foraging efficiency.


  4. Nutritional Stress Highlighted: The study emphasizes how parasitic infections lead to nutritional imbalances and physiological strain on honeybee colonies.


  5. Overlooked Threat: Lotmaria passim, though widespread, often remains under-monitored. The findings urge beekeepers to expand their parasite management strategies to include this emerging threat.


Why Should You Care?


Parasites can silently sap the vitality of your bees, impacting not just colony survival but also honey production and pollination services. By staying informed, you can make evidence-based decisions to protect your hives from these microscopic threats.


This study underscores the need for integrated management strategies, such as improving diet quality or exploring novel parasite controls. For New Zealand beekeepers and honey exporters, proactive measures to address these infections will also ensure sustainable operations and bolster the global reputation of your honey products.


Stay vigilant, stay informed, and keep your bees thriving!
