Abstract: Cereal cyst nematodes in the Heterodera avenae group are recognized as one of the important pest of wheat in China. In order to seek for the biocontrol agents for CCN,20 parasitic fungi were isolated from CCN cysts and eggs, which was evaluated in pots.Eleven isolates (Z2 and Z4) provided good control of CCN in pots,with average control efficacy reach 50%.Z2 and Z4 strains respectively belonged to Pleosporalesand Paecilomyces sp through morphological characteristics observation and ITS sequence assayed.Then it preliminary studied on the biological characteristics of the two strains.
