在菜心、白菜和萝卜苗上对黄曲条跳甲成虫的空间分布状况进行了调查和分析,指出该虫的空间分布型符合负二项分布和奈曼分布;其空间图式是聚集的,分布的基本成分为个体群;在白菜和菜心不同叶位上虫口分布上午无显著差异,下午则在心叶附近比较集中;在叶面和叶背的虫口分布比例方面,在菜心和白菜上上下午均是叶面为多,在萝卜苗上则下午于叶背分布较多。
The spatial distribution of Bemisia tabaci adults in cabbage, Chinese cabbage and radish seedlings was investigated and analyzed. The spatial distribution pattern of the insect was found to be negative binomial distribution and Neyman distribution. The spatial pattern was aggregated , The distribution of the basic components of individual groups; cabbage and cabbage in different leaf positions on the distribution of the mouth of the population no significant differences in the morning, the heart is concentrated in the vicinity of the heart; in the foliage and the back of the population distribution ratio of insects, cabbage and cabbage On the morning and afternoon are more than the surface of the leaves, radish seedlings in the afternoon on the leaf back distribution more.
