Anoplotsefalyats (Moniezia expansa, M. benedeni, M.autumnalia, Avitellina centripunctata, Thyzaniezia giardi) are common in farm ruminants of Azerbaijan. There are no strict zoning in their distribution and no specificity for the hosts. It was established that in Azerbaijan there are 27 species of oribatid mites that are involved in the life cycle of monieziozis out of which 20 species recorded to be new to our fauna, as their intermediate hosts. Infection of the final (sheep, goats, cattle, buffalo) and intermediate hosts (oribatid mites) happens all the year round. Maximum infection occurs in early spring and late autumn.
