First record of mycetophagous nematode aphelenchus avenae in Iraq with description and testing their propagation on different fungus culture

الملخص EN

Aphelenchus avenae was isolated from the wheat crown in Summel distract- Duhok, Kurdistan region-Iraq infected by a crown rot disease which is caused by Fusarium spp; wheat's crown culturing on Potato Dextrose Agar (PDA) and incubating at 25°C A.

avenae was found associated with fungal culture which meant that fungal nematode was parasitic on crown rot fungi on wheat crown, this species was described for the first time in Iraq.

Fungal Nematode incubated with Fusarium graminearum, F.

oxysporum and Verticillium dahliae reproduce in both solid and liquid media, best results of nematode reproduction were recorded on F.

graminearum followed by F.

oxysporum and V.

dahlia respectively.

The nematode A.

avenae did not reproduce on the liquid media of these fungi.
