Isolation and Characterization of a Parasitic Nematode, Oscheius myriophila (Nematoda: Rhabditida), Associated with European Mole Cricket, Gryllotalpa gryllotalpa (Orthoptera: Gryllotalpidae)

Avrupa Danaburnu Gryllotalpa gryllotalpa (Orthoptera: Gryllotalpidae) ile İlişkili Parazitik Bir Nematod Olan Oscheius myriophila (Nematoda: Rhabditida)’nın İzolasyonu ve Karakterizasyonu

Anematode strain was isolated from a population of European mole cricket, Gryllotalpa gryllotalpa L. (Orthoptera: Gryllotalpidae), collected from the Black Sea Region of Turkey. Based on morphometrical and molecular (ITS partial sequence) properties, it was identified as Oscheius myriophila. This species of dauer juveniles resembled with Rhabditis myriophila (Poinar, 1986), however, it differs in having larger body length (571.3-693.9) and distance from the head to the nerve ring (100-116.8), and smaller tail length (53.4-76.8) and width at anus (10.4-13.8). This stage is the third-stage juvenile enclosed in a second-stage cuticle that surrounds the nematode like a sheath. The sequences of the ITS region of rDNA confirmed this identification. The species is recorded for the first time from G. gryllotalpa
