摘要： An actinomyce (S07) isolated from a cyst of Heterodera filipjevi was characterised as Streptomyces anulatus by morphological, physiological and biochemical criteria and 16S rRNA analysis. The biocontrol potential of S07 was evaluated against both Heterodera avenae and H. filipjevi. After an initial assay of S07 culture filtrates on egg hatch in vitro and juvenile survival, the effect on these cereal cyst nematodes (CCN) was evaluated in the greenhouse using naturally infested soil and in the field over two consecutive years. The results showed that S07 significantly reduced the population densities of CCN females in wheat, concurrently increasing grain yield. It is concluded that S07 offers potential as a commercial biocontrol agent.
