| 摘 要： | 空心莲子草叶甲成虫主要取食空心莲子草顶端幼嫩叶片,虫子的分布概率(Y)与各节叶(X)的关系是:Y=153.43-23.32X;卵在植株上的垂直分布概率以第四叶片上最高,呈抛物线Y=24.80 28.31X-3.41X~2;幼虫有群集性,多数在顶端第一、二叶叶背上取食,越老的叶片,虫数越少,两者呈负相关;Y=235-31.54X.老熟幼虫化蛹位置大部分在茎杆第五节,各节蛹的分布Y=411.56 199.81X-16.31X~2。

| Abstract: | This paper deals with the vertical distribution of different stages of alligatorweed flea beetle, Agasicales hygrophila, on the host plant in the field. It shows that adult and larval stages are active on the upper part of the plant and eggs are laid on the middle, pupation occures in the lower part of the stem. |
