Abstract
Whereas in several parts of the world varroa is the major pest affecting ap iculture, in others the parasite is unknown to many beekeepers because of t he little damage it causes to bees. The impact of the mite Varroa jacobsoni is related to the climatic conditions and the races of Apis mellifera bees in each region where the pest exists. In the present study, the mite infes tation levels were assessed to determine the evolution of the pest in Afric anized bee colonies in Southern Brazil. The current level of infestation wa s considered low, approximately two mites per one hundred adult bees. This result is similar to that obtained for the same apiary almost five years ag o and for others distributed in various regions of Brazil. In the present s tudy, on average, 61% of the total varroa population was found in the worke r brood.
