湖北襄阳禾谷孢囊线虫（Heterodera avenae）生活世代及发生动态研究
Study on Life Cycle and Infection Dynamics of Cereal Cyst Nematode (Heterodera avenae) in Xiangyang City
摘要
Abstract
The occurrence and distribution of cereal cyst nematode ( CCN) ( Heterodera avenae) were investigated in Hubei province .Through sampling in seriously -diseased wheat field in Xiangyang city , we observed the morphology of H.avenae at dif-ferent developmental stages , and studied its population dynamics .The results showed that this nematode distributed in Xiangyang , Tianmen, Qianjiang, Zhongxiang and Hanchuan .The most serious CCN disease occurred in Xiangyang , in which there were 12.5 living cysts in 100 mL soil sample.The 2-instar larvae of CCN began to intrude into the young wheat roots on the 20th day after so-wing, and the larvae density in the roots reached a peak on the 143rd day after sowing.The larvae in wheat roots fed, did harm, and developed to white females on the 158th day after sowing.The developed white female came out from wheat roots , and its density reached the maximum on the 174th day after sowing .关键词
