MORETTO, Geraldo  y  DE MELLO JR, Leonidas J.. Infestation and distribution of the mite varroa jacobsoni in africanized honey bee (apis mellifera) colonies. INCI [online]. 2001, vol.26, n.9, pp.394-396. ISSN 0378-1844.

Whereas in several parts of the world varroa is the major pest affecting apiculture, in others the parasite is unknown to many beekeepers because of the 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 infestation levels were assessed to determine the evolution of the pest in Africanized bee colonies in Southern Brazil. The current level of infestation was considered low, approximately two mites per one hundred adult bees. This result is similar to that obtained for the same apiary almost five years ago and for others distributed in various regions of Brazil. In the present study, on average, 61% of the total varroa population was found in the worker brood.
