Vertical dispersal of the entomopathogenic nematode, Steinernema feltiae was tested with earthworms in soil columns. One of them is grey worm, Aporrectodea caliginosa and the other is reddish-brown worm, Lumbricus rubellus. Nematode vertical dispersal was estimated after a 3-week period. S. feltiae reared in the last instar of the greater wax moth, Galleria mellonella. Vertical dispersal of S. feltiae was increased in the presence of earthworms. For this motion, L. rubellus is more effective than A.caliginosa

Böcek paraziti nematod, Steinernema feltiae Rhabditida: Steinernematidae ’nin dikey dağılımı üzerine toprak solucanlarının etkisi

Öz

Böcek paraziti nematod, Steinernema feltiae’nin dikey dağılımı toprak kolonlarda, toprak solucanları ile test edilmiştir. Bu toprak solucanlarından birisi gri toprak solucanı Aporrectodea caliginosa, diğeri ise kırmızımsı-kahve renkli toprak solucanı Lumbricus rubellus’dur. Nematodun dikey dağılımı 3 haftalık bir period sonrası değerlendirilmiştir. S. feltiae büyük mum güvesi, Galleria mellonella’nın son evresinde yetiştirilmiştir. S. feltiae’nin dikey dağılımı toprak solucanlarının mevcudiyetinde artış göstermiştir. Bu hareket için, L. rubellus, A.caliginosa’dan daha etkili olmuştur
