摘　　要：初步调查研究了河南驻马店蚁封林场7年生美国杂交杏李李小食心虫幼虫的种群动态,结果显示,李小食心虫幼虫在美国杏李上的空间格局为聚集型,而每个果实中李小食心虫幼虫分布均匀,分布的基本成分是个体群,个体间相互吸引。不同调查时间同一枝条上李小食心虫的幼虫密度不相同。李小食心虫幼虫存在明显的扩散性和空间移动性。Preliminary investigation and analysis in ＂Meiguoxingli＂plum were conducted on the population dynamics of Grapholitha funebrana larvae. Results showed that the distribution pattern of Grapholitha funebrana larvae on ＂Meiguoxingli＂ plum belonged to aggregation distribution in general, but evenly distribution in each fruit. The basic component of the larvae distribution was the individual colony, but colonies attracted one another. The density on the same branch of the Grapholitba funebrana larvae was not the same in different time, and there were obvious diffusivity and the space mobility in population dynamics of Grapbolitha funebrana larvae.
