Abstract
Ontogenic variations of esterase isozyrnes and biochemical genetic polymorphisms were investigated on the Syrian and Carniolan races and their hybrid genotypes. Healthy and infested samples with Varroa mites showed similar pattern for the same developmental stage. Banding pattern differs according to developmental stages. where positive bands which were present in larval and pupal stages disappeared in the adult stage.
Comparisons between the two races and their F1 hybnd p-oved the presence of considerable pattern variations The Carnlolan race preserued high levels of electrophoretic variability in all developmental stages and under dlf~erent conditions of Varroa infestation. compared to the Synan race and hybrid genotype Esterase patterns appeared along different stages in the Syrian race and hybrid genotype. Esterase patterns detected in the different stages of the SY"8n, and Carniolan races and their hybrid genotypes showed that the great majority of isozyrnes were monomorphic.
