摘　　要：通过对3块标地资料的分析,得出锈色粒肩天牛的扩散规律遵从指数曲线y=aebx(b<0),只是在不同虫口密度下,参数a、b取不同的值,进一步确定带虫苗木调运是锈色粒肩天牛蔓延扩散的主要传播途径,加强检疫是防止锈色粒肩天牛蔓延扩散的有效手段。By analyzing of data from three sample plots, spread laws of Apriona swainsoni accorded with the equation of （b〈0）, of which a and b changed with insect density. We confirmed that carrying seedlings attacked insects was a major route of transmission. So strenthening of quarantine was avilable to spread of Apriona swainsoni.
