Publikováno v: Journal of Apicultural Research. 37:115-123
SUMMARYThe parasitic mite Varroa jacobsoni infests the brood cells of its host Apis mellifera and reproduces in them. The distribution of the mites in the brood cells is an important aspect of the parasite's biology, with implications for the estimat
