| Abstract: | This paper deals with relative biology characteristics of rice root nematodes (Hirschmanniella oryzae): morphology feature, infection cycle, adaptive faculty to temperature and humidity and so on. The result of investigation showed that this nematodes were widely distributed in all the rice growing regions of Hunan. The occurrence and fluctuation dynamics curve showed that there were three population peaks of the nematodes in rice field of Hunan in a year. |
