THE INFLUENCE OF ENERGY FOOD INTAKE AND QUANTITY OF UNCOVER LARVAE ON POLLEN COLLECTION EFFICIENCY
The purpose of the paper is to observe the interrelations that are established between the quantity of pollen collected by bees and some internal factors of the bees family: the amount of energy food, cover and uncovered brood. The methods used consisted of observing the internal situation of the bees families, taking pictures, putting pollen collectors, collecting raw data, statistical interpretation of obtained data. Four eperimental plots were organized, each with different contributions of honey and uncovered brood. Colonies had the same power. The collection period using pollen collectors was 24 hours. Pollen from each family was linked to its internal situation. The internal situation of the family was expressed both in cell number and percentage. Numerical results have given quite large variations due to the multitude of internal fluctuating factors of any family. The quantities of pollen obtained were between 25.60 and 262.40 grams. We applied Fisher and Tukey tests. Multiple correlation test revealed positive correlation between the amount of brood and pollen intake, and negative correlation between the amount of honey in the hive and pollen intake. There were also situations in which the absence of juveniles lead to increased intake of honey and pollen.
