    21 parasite species have been found in structure of variety of parasite species from hybrid sheep (mouflon × domestic sheep hybrids) contained within limited grazing territories of foothill zones of Armenia. These included 9 species of nematodes, 4 of cestodes, 3 of trematodes, 3 of ixodid ticks and larvae of nasopharyngeal gadfly Oestrus ovis and sheep ked Melophagus ovinus. An analysis of paths of circulation of larvae of some biohelminthes, particularly Dicrocoelidae and Protostrongylidae, realized through invertebrate intermediate hosts (land snails) have shown that mean infection of the latter varied from 2,5 to 8,0 %.У гибридных с муфлоном овец, содержащихся в условиях ограниченных пастбищных территорий предгорной зоны Армении, выявлен 21 вид паразитов, из которых большая часть гельминты (16 видов). Нематоды представлены 9 видами, цестоды – 4 и трематоды – 3 видами. Установлено паразитирование также 3 видов иксодовых клещей и 2 видов насекомых. Исследования путей циркуляции личиночных стадий дикроцелий и протостронгилид, осуществляемых при участии беспозвоночных животных, в частности, наземных моллюсков показали их естественную зараженность от 2,5 до 8,0%
