Méhvérzés

Méhvérzés is a Hungarian term that translates to "bee bleeding" and refers to a phenomenon observed in honey bee colonies where adult bees appear to exude a reddish fluid from their bodies. This fluid is not blood in the mammalian sense, as insects do not have a circulatory system with red blood cells. Instead, the substance is likely hemolymph, the insect equivalent of blood, mixed with other internal fluids and possibly digestive material.

The exact causes and implications of méhvérzés are not fully understood, and it can be a symptom of various underlying issues within a colony. It is often associated with disease, particularly viral infections like Deformed Wing Virus (DWV), which can weaken bees and lead to internal damage. Pesticide exposure is another suspected cause, as certain chemicals can disrupt bee physiology. Stress from environmental factors such as poor nutrition, extreme temperatures, or overcrowding may also contribute.

Observing méhvérzés in a bee colony is generally a cause for concern for beekeepers. It indicates that something is compromising the health and vitality of the bees. While not a disease in itself, it is a visible sign of distress that warrants further investigation into potential causes like pathogens, parasites (such as Varroa mites), or environmental stressors. Addressing the root cause is crucial for the survival and well-being of the colony.
