FACTORS AFFECTING THE VARIABILITY OF THE HEAD DEPARTMENT MASS OF THE HONEYBEE APIS MELLIFERA L.

We studied the age variability of the head department mass and process modification under the influence of physical and chemical environmental factors. The mass of the head departments is steadily decreasing from the beginning of the imaginal stage by the end of the life. This process is intensified by low-concentration carbohydrate forage consumption, content of pollutants or anesthesia in the atmosphere of CO₂ or N₂.Reducing the mass of the head departments accompanied by decreasing their water content and the temperature of maximum hypothermia lowering.
