摘　　要：文章通过对橄榄星室木虱若虫在田间的空间分布状态的调查和分析,指出橄榄星室木虱若虫在林间呈聚集分布,而其种群的聚集是由于其自身的特性与环境因素的差异性共同作用所致。橄榄星室木虱若虫在橄榄树冠上、下层之间或同一复叶不同区段之间的虫口密度差异不显著;而在同一叶片正反面的差异极显著,叶片背面的虫口密度比正面的大许多。The spatial distribution of the nymph of Pseudophacopteron canarium Yang et Li was investigated and analyzed in the article, the spatial distribution pattern of the nymph of P. canarium is an aggregative one and the basic component of distribution is the colony. biological and ecological characteristics, and the Aggregation of the nymph of P. canarium largely resulted from its environmental factors around them. The density difference of the nymph of P. canarium between the superstratum and the substratum in the crown of an olive, or between the different sections of the same olive compound leaf, is not very notable ,but it is very prominent on the different surfaces of the olive leaflet and the density of the nymph of P. canarium on the frontispiece of an olive leaflet is much more great than the reverso.
