朱砂叶螨、侧杂食线螨在茄子、辣椒、豇豆三种蔬菜上的空间分布里聚集型分布,这是由它们的生物学特性造成的.朱砂叶螨在茄子和辣椒不同叶层上的虫口密度是中部>下部>上部;在豇豆上则上、中、下部的密度相差不大.侧杂食线螨在茄子和豇豆不同叶层上的虫口密度是中部>上部>下部,在辣椒上则是上部>中部>下部.
Tetranychus cinnabarinus and Tetranychus urticae were clustered in the spatial distribution of eggplant, peppers and cowpeas, which were caused by their biological characteristics. The density was middle> lower> upper, and on the cowpeas, the density of middle, middle and lower part was not different.The pest density of the lateral omnivorous line mites on the different layers of eggplant and cowpea was middle> top> bottom, while on pepper Upper> middle> lower.
