    THE IMPACT OF BREEDING HONEYBEES IN DIFFERENT REGIONS OF SERBIA AND BOSNIA AND HERZEGOVINA ON THEIR MORPHOMETRIC PARAMETERS

    In order to facilitate better comparative analysis, a sample of bees originating from Slovenia was also analyzed. A comparison was made between the values of the morphological parameters of the front wings of bees from the following locations: Svojnovo (I), Ražanj (II), Prokuplje (III), Zlatar (IV), Negotin (V), Čajniče (VI), Tuzla (VII), Višegrad (VIII), Bijeljina (IX) and Slovenia (X). The aim of the study was to determine the existence of differences between bees from various sites. The standard methodology included the measurement andanalysis of 11 angles on the front wing (A4, B4, D7, E9, J1, J16, K19, L13, N23, G18 and O26), wing length and width, and cubital index on samples of 15 bees each. Univariate statistical analysis was performed, and comparisons were made between locations using Duncan's Studentized Multiple Range Test. Based on the results of the statistical analysis, a highly significant difference was found between location I and locations II, IV, VII, VIII, and IX for angles A4 and B4. When comparing the value of angle E9, a statistically significant difference (p<0.01) was found between location IV and all other locations. In addition to the established differences between bees from individual localities, there are similarities that indicate the maintenance of a stable population of A. m. carnica in the region.
