Harvesting bee products is a critical stage in apiculture that requires careful management to ensure quality, productivity, and sustainability of the beekeeping enterprise. For Agriculture and Extension professionals in Kenya, understanding how to manage bee pests and diseases and conduct thorough hive inspections is essential to maintain healthy colonies and optimize product yield. This chapter addresses the key aspects of pest and disease control and the inspection procedures that safeguard hive health, which directly impact the livelihoods of smallholder farmers and commercial beekeepers alike.
Managing bee pests and diseases is fundamental to sustaining productive beekeeping operations in Kenya. Pests and diseases can severely reduce colony strength, honey yield, and even cause colony collapse if not properly controlled. Extension officers and farmers must be equipped with knowledge to identify, prevent, and manage these challenges to maintain hive vitality and ensure continuous production of quality bee products.
Understanding the terminology related to bee pests and diseases clarifies communication and enhances effective management practices. The following key terms are frequently used in apiculture and must be clearly defined.
A bee pest refers to any external organism that infests or attacks honeybee colonies, causing harm to the bees or the hive structure. Examples include the Varroa mite and wax moth, which feed on bees or their comb, weakening the colony and reducing productivity.
A bee disease is an internal disorder caused by pathogens such as bacteria, viruses, fungi, or protozoa that infect bees or brood, compromising colony health. Common diseases in Kenya include American foulbrood and Nosema, which affect brood development and adult bee longevity.
Infestation describes the presence and multiplication of pests within a bee colony at levels that cause damage or stress to the bees. Infestation intensity can vary and requires monitoring to determine when control measures are needed.
Infection refers to the invasion and multiplication of disease-causing organisms inside the bees or brood, leading to physiological dysfunction. Infections may be chronic or acute and often necessitate specific treatment protocols.
Colony collapse is the sudden loss of the majority of worker bees in a colony, resulting in a weak or non-viable hive. This can be triggered by severe pest infestations, disease outbreaks, or environmental stressors, leading to economic losses for beekeepers.
Regular inspection of bee hives is a vital practice for early detection and management of pests and diseases. In Kenya’s diverse agro-ecological zones, timely and systematic hive inspections enable beekeepers to maintain healthy colonies and maximize honey production.
Hive inspections serve multiple purposes, including assessing colony strength, detecting signs of pest infestation or disease, monitoring queen performance, and evaluating honey stores. Effective inspections help prevent losses and inform management decisions such as treatment application or re-queening.
The timing and frequency of hive inspections depend on seasonal conditions and colony development stages. During active nectar flows, inspections should be conducted every 7 to 14 days to monitor rapid colony changes. In dry seasons or periods of low activity, monthly inspections suffice to check hive integrity and pest presence.
Proper inspection involves systematic opening of the hive, frame-by-frame examination, and careful observation of bee behavior, brood pattern, and comb condition. Essential tools include a hive tool to separate frames, a bee brush to gently remove bees, and a smoker to calm the colony. Protective clothing prevents stings during this process.
During inspections, beekeepers should look for specific indicators such as:
Identifying these signs early enables prompt intervention to safeguard colony health.

Create a free accountThis chapter focused on the management of bee pests and diseases, beginning with clear definitions of key terms and the procedures for inspecting bee hives to detect health issues early. It examined various bee pests and diseases, including viral infections, Nosemosis, Varroa mites, the Small Hive Beetle, carpenter bees, bumblebees, ants, mites, and the lesser wax moth, highlighting their impact on bee colonies. Effective methods for controlling these pests and diseases were explored, emphasizing the importance of timely intervention. The chapter also detailed the process of carrying out thorough hive inspections to monitor colony health. Additionally, it covered the preparation of accurate records for bee pests and diseases control, which is essential for tracking treatment outcomes. The practical steps involved in implementing pest and disease control measures were described to ensure colony protection. Finally, the chapter addressed the preparation of appropriate control methods tailored to specific pest and disease challenges in bee production.
