Sažetak
Honeybee queen quality control is estimated by monitoring of spermatheca morphological characteristics. Three queens were taken from 28 Croatian queen breeders. The quality control was carried out on Croatian native honeybee queens (Apis mellifera carnica). Diameter of spermatheca and number of spermatozoa were analyzed. After dissection bronchial net was removed from spermatheca. Calibrated Dino Capture camera was used to measure diameter of spermatheca. The average measured value of diameter was 1.0233 + 0.056 (min. 0.934 mm, max. 1.197 mm). Content of spermatheca was dispersed in 0.5 ml saline solution. The number of spermatozoa was counted in Neuebauer haemocytometer. The average measured value of spermatozoa number in 1 ml was 3 856 000 + 1 976 (min. 700 000, max. 11 600 000). One unfertilized queen was determined in 64 observed samples.
