Oscheius rugaoensis and Pristionchus maupasi, two new records of entomophilic nematodes from Iran

摘要

A survey was carried out to determine the natural pathogens of the white grub, Polyphylla adspersa (Coleoptera: Scarabaeidae), in the Mashhad region, North East of Iran. Here, three species of entomophilic nematodes, namely Oscheius rugaoensis, Pristionchus maupasi and P. pacificus, were isolated from the white grub larvae. Measurements, illustrations, and SEM photographs of the new record are provided and their phylogenetic analyses based on 18S rDNA and ITS genes were discussed. This is the first report of Oscheius genus and P. maupasi from Iran.
