The number of spermatozoa in drones of Apis Mellifera Carnica Poll. Reared from inbreed colonies and colonies infested with Varoa jacobsoni oud.

Influence of inbreeding and varroa mite infestation on a number of spermatoza in Carniolan honeybee drones (Apis mellifera carnica) was investigated. Noninbreed drones from clonies treated against varroa represented control group. The number of spermatozoa was counted by the method described by Koeniger et al. (1990). Influence of varroa mite and inbreeding significantly (p<0, 05) decreased the number of spermatozoa in comparison to control group. Significantly higher influence on spermatozoa development has inbreeding than varroa mite (p<0, 05).
