NOSEMA DISEASE

​

 

Nosema disease is a fungal infection that affects honeybees. It is caused by the microsporidian parasites Nosema Apis and Nosema Ceranae, which can have a severe impact on the health of individual bees and the overall strength of a colony. Nosema disease is a common problem that beekeepers face, and understanding its symptoms, treatments, and prevention measures is essential for maintaining healthy hives.

​

NOSEMA CERANAE

This is a fungal disease that affects honeybees, specifically the midgut epithelial cells. It is caused by a unicellular parasite called Nosema Ceranae. This disease was first discovered in Asia, and it has since spread globally.

​

Symptoms: One of the primary symptoms of Nosema Ceranae is dysentery. Dysentery is when honeybees are unable to control their excrement, and they defecate within the hive. This can lead to the death of the colony. Honeybees that are infected with Nosema Ceranae may also have a shorter lifespan, reduced food consumption, and lower brood production.

​

Treatments: There are several treatments available for Nosema Ceranae, but the most effective is using Fumagilin-B. This medication should be administered in the fall or winter before brood production begins. Other treatments include thymol, which can be used as a food supplement or as a fumigant. Oxalic acid is also effective at controlling Nosema Ceranae, but it should not be used during the honey flow season.

​

Prevention measures: Preventing Nosema Ceranae is critical in maintaining a healthy colony. One prevention measure is to keep the hive clean and dry. This can be done by removing any dead bees or debris from the hive and ensuring adequate ventilation. Feeding colonies with clean, high-quality pollen supplements can also help prevent Nosema Ceranae. Other prevention measures include maintaining a low-stress environment for the colony and keeping the colony free of other diseases and pests.

​

Cures: There is no cure for Nosema Ceranae, but it can be controlled using various treatments as discussed above. It is important to detect the presence of Nosema ceranae in the hive early on to prevent the spread of the disease. Beekeepers should regularly inspect their colonies for signs of Nosema Ceranae and other diseases.

​

Nosema Ceranae is a fungal disease that affects honeybees and can lead to dysentery, reduced food consumption, and lower brood production. Fortunately, there are treatments available, including Fumagilin-B, thymol, and oxalic acid. Prevention measures, such as keeping the hive clean and dry, feeding colonies with clean pollen supplements, and maintaining a low-stress environment, can also help prevent the disease.

​

NOSEMA APIS

This is a fungal parasite that infects the digestive system of honeybees. The parasite can cause a significant impact on the health and productivity of honeybee colonies. Nosema Apis is one of the most prevalent diseases of honeybees, affecting colonies worldwide.

​

Symptoms: The symptoms of Nosema Apis infection may not be immediately visible, but they become more evident as the disease progresses. Infected bees may exhibit a reduced lifespan, decreased vigour, and weakened immune system. The most noticeable symptom of Nosema Apis is dysentery, which is the presence of dark streaks or spots of faeces near the entrance of the hive. Bees with this disease may also show a reduced ability to forage for food.

​

Treatments: To treat Nosema Apis infection, beekeepers should first confirm the diagnosis by sending a sample of infected bees to a laboratory for analysis. A range of treatments is available for Nosema Apis, including natural and synthetic remedies.

​

One effective treatment for Nosema Apis is fumagillin, which is an antibiotic. Fumagillin is administered to the bees by mixing it with sugar syrup, which is then fed to the colony. Fumagillin is an effective treatment that can be applied at any time of year, but it should not be used if honey supers are present on the hive.

​

Prevention measures: Prevention is the best defence against Nosema Apis infection. Beekeepers can take several measures to minimize the risk of infection in their colonies. These include:

​

• Keeping the colony in a healthy condition by providing a well-balanced diet and proper ventilation

• Avoiding the transfer of used equipment from an infected colony to an uninfected one

• Reducing stress factors such as overcrowding, poor nutrition, and frequent transportation

• Re-queening the colony with a queen that has been selected for disease resistance

• Providing bees with access to clean water sources

• Cleaning and sanitizing beekeeping equipment regularly

​

Cures: While there is no cure for Nosema Apis, effective treatments are available to manage the disease. Additionally, beekeepers can take preventive measures to reduce the risk of infection in their colonies.

​

Nosema Apis is a significant disease that can have a significant impact on the health and productivity of honeybee colonies. Beekeepers must remain vigilant to identify and manage this disease promptly. With proper treatment and preventive measures, beekeepers can reduce the risk of Nosema Apis infection and keep their colonies healthy and productive.
