| Abstract: | The population dynamics of Tryporyza incertulas in years from 1980 to 2000 were analysed. The result showed that the annual numbers of T.incertulas are different and obviously intermittent. The weather (temperature, rainfall) of winter and spring,the cropping system and natural enemies were the most important factors affecting the number of T. incertulas. Some practical methods for controlling this insect species are introduced in this paper. |
