摘要
利用最近邻体法研究了朱砂叶螨若螨在棉叶上的分布。结果表明：在试验的３７个样本中，有１９个样本呈聚集分布，１２个样本呈随机分布，６个样本呈均匀分布。聚集程度随密度的降低而增加，密度增加逐渐趋向随机分布和均匀分布。
The distribution of nymph of T.cinnabarinus on cotton leaves was investigated by nearest neighbor analysis.The spatial pattern of nymph of T.cinnabarinus in 19 of 37 samples was aggregative,12 stochastic and 5 mean.The lower the density,the more aggregative the spatial pattern of nymph,and as the density increased,the spatial pattern tended to be stochastic and mean.
