2012年在山东省调查小麦田块242个,禾谷孢囊线虫( CCN )发生率为50.0%;聊城和菏泽发生普遍而严重,日照和临沂只是零星轻度发生;发现CCN新分布县/区10个。2013年在胶东地区调查小麦田块64个,CCN发生率为60.9%;与2012年相比,青岛和威海的CCN发生率升高,但发生水平明显较低;发现CCN新分布县/区1个。

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.
