Özet
Çalışma Muş ilinde bazı meralarda nematod fauna yapısını incelemek üzere 2015 yılında yürütülmüştür. Muş-Bingöl karayolu üzerinde bulunan meralardan her 5 km'de bir durularak toprak örnekleri alınmıştır. Toprak örneklerinden nematodların elde edilmesi için Petri kabı yöntemi kullanılmıştır. Çalışmada nematod faunasına ilişkin 27 cins ve bir tür tespit edilmiş olup, bunlardan 8 cins bitki paraziti, 9 cins bakterivor, 4 cins fungivor, 1 cins predatör ve 5 cins omnivor gruba ait nematodlardan oluşmaktadır. Bitki paraziti nematodlardan Helicotylenchus, Tylenchus, Pratylenchus ve Merlinius cinsleri; bakterivorlardan Acrobeloides, Cephalobus ve Monhystera; fungivorlardan Ditylenchus, Tylencholaimus ve Aphelenchus; predatörlerden sadece Mononchus; omnivorlardan ise Prodorylaimus ve Aporcelaimellus cinslerinin ön planda olduğu belirlenmiştir. Trofik gruplardan bitki paraziti nematodların faunadaki oranı %32, bakterivorların %33, fungivorların %32, predatör ve omnivorların oranı ise %29 olarak hesaplanmıştır. Trofik grupların dağılımının birbirine yakın değerler aldığı görülmüştür. Sonuç olarak, çalışma alanındaki bitki paraziti nematodların çeşitlilik ve yoğunluklarının yüksek olmadığı ve serbest yaşayan nematodların ise orta seviyede bir yapıya sahip oldukları söylenebilir
The study was conducted to investigate nematode faunal structure in some pastures of Muş province, in 2015. Soil samples were taken from pastures by stopping at every 5 km of Muş-Bingol road. Nematodes were reovered from soil samples by using petri-dish method. Twenty nine genera and one species fron the nematode fauna were identified.; 8 plant parasitic, 9 bacterivores, 4 fungivores, 1 predator and 5 genera belonged to omnivore groups. The prominent genera were Helicotylenchus, Tylenchus, Pratylenchus and Merlinius as plant parasitic group; Acrobeloides, Cephalobus and Monhystera as bacterivores; Ditylenchus, Tylencholaimus and Aphelenchus from fungivores; Mononchus as predators; Prodorylaimus and Aporcelaimellus as omnivores. The proportions of trophic groups in the fauna in terms of abundance were calculated as 32% plant parasitic nematodes, 33% as bacterivores, 32% as fungivores and as 29% omnivores. The results revealed that all the trophic groups had close diversity and abundance values, except the predator group which was the least in the fauna. It might be concluded that, in the study area, the diversity and abundance of plant parasitic nematodes were not very high and free-living nematodes were in a fair state
