摘要
分析了 1 980～ 2 0 0 0年三化螟种群数量变动情况 ,发现年度间的变动不一致 ,有明显间歇性。认为冬春气候 (气温、雨量 )、耕作制度、天敌因素等与三化螟为害密切相关 。
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.
