| 摘 要： | 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。

| Abstract: | The spatial distribution pattern of the adult of the striped flea-beetle, Phyllotreta striolata Fabricius, on vegetable fields were studied. The results showd that:(a)The spatial distribution of the insect pest confotmcd to negative binomial distribution and Neyman distribution.(b)The spatial pattern of the pest is an aggregative one and the basic component of distribution is the colony.(c)In the afternoon, on the Chinese cabbage and the flowering cabbage 81% of the pest concentrate on the youngest leaf and 2 leaves around it, and on the radish the greater pars of the pest concentrate on the back of the leaves. |
