| Abstract: | The investigation was carried out in 242 wheat fields of Shandong Province in 2012 , and the occurrence ratio of cereal cyst nematode （CCN） was 50.0%.Among which, the occurrence conditions in Li-aocheng and Heze were common and severe , and those in Rizhao and Linyi were sporadic and slight .The CCN was found in 10 counties （districts） for the first time.Sixty-four wheat fields in eastern Shandong Prov-ince were investigated in 2013 , and the CCN occurrence ratio was 60 .9%.Compared with 2012 , the CCN oc-currence ratios in Qingdao and Weihai were higher , but the occurrence levels （ the densities of female or cyst population） were obviously lower.The CCN was found in 1 county （district） for the first time. |
