Varroa Destructor Mite: The Causative Agent of Bee Varroosis
Morphological identification of the Varroa destructor mite under the microscope. Structural features of the causative agent of bee varroosis in veterinary parasitology.
Blood and bone marrow morphology, clinical cases and diagnostic algorithms. Most of the library is in Russian; the English section is growing.
Most of our material is written in Russian — that is the working language of the community. A few pieces exist in English; the rest of the library is one click away and the photographs need no translation.
