摘　　要：2009年5月对江苏省5个地区的22个县市小麦孢囊线虫病发生情况进行了初步调查,共采集76份含根系和根际土壤的样本,经分离与鉴定表明,小麦禾谷孢囊线虫(Heterodera avenae,CCN)在徐州、连云港、宿迁和盐城等地区都有分布,检出率为35%。徐州的沛县、丰县、邳州和睢宁等4个县市的小麦孢囊线虫病检出率超过90%。其中,丰县华山镇、沛县河口镇和丰县城东的田块孢囊密度较大,每100 mL土壤的平均孢囊数分别为161、159个和112个,每个孢囊的平均含卵量分别为187、190粒和174粒。这是小麦孢囊线虫病在江苏省发生的首次报道。In May of 2009, a preliminary survey of the cereal cyst nematode （CCN） was carried out in wheat fields in 22 counties of Jiangsu Province in China. A total of 76 samples with roots and soils were collected. The results of extraction and identification demonstrated that Heterodera avenae was distributed in Xuzhou, Lianyungang, Suqian and Yancheng districts. The incidence rate was 35%. The CCN incidence rates in wheat growing areas of Peixian, Fengxian, Pizhou and Suining counties of Xuzhou were higher than 90%. The cyst densities in the fields in Huashan Town （Fengxian）, Hekou Town （Peixian） and suburban Fengxian were higher than that in other areas investigated. The average cyst and egg numbers in these areas were 161, 159 and 112 cysts/100 mL soils, respectively, and 187, 190 and 174 eggs/cyst, respectively. This is the first report of CCN distribution in Jiangsu Provnce.
