Gregarinida and Mermithida parasitism in the Pterostichus melanarius (Coleoptera, Carabidae) in Dnipropetrovs’k region

Viable parasitic Mermithidae nematodes were revealed in the abdominal cavity of ground beetles imago Pterostichus melanarius (Illiger, 1798). Some unicellular parasites of suborder Eugregarinina were found in the intestinal tract of the P. melanarius . The percentage of nematodes and sporozoa invasion in P. melanarius was assessed for the conditions of Dnipropetrovs’k region. The carabus ability to be a host in the life cycles of nematodes and gregarines was analyzed.
