| 摘 要： | 测定龟纹瓢虫各虫态捕食牛蒡长管蚜的功能反应和寻找效应,结果表明,其功能反应均属于HollingⅡ型圆盘方程式,寻找效应与自身密度的关系可用Hassell数学模型描述。龟纹瓢虫对牛蒡长管蚜具有较强的捕食能力。龟纹瓢虫一、二、三、四龄幼虫和成虫对牛蒡长管蚜若虫的日最大捕食量分别为16.8,24.0,58.1,84.7,76.3头。龟纹瓢虫对牛蒡长管蚜的捕食作用在一定的空间范围内受其自身的密度制约,相互间存在干扰,干扰反应符合Hassell模型。

| Abstract: | The experiment results showed that the functional response of predation on Uroleucon gobonis by the 1st、2nd、3rd and 4th instars and adult of Propylaea japonica belonged to the type of Holling Ⅱ.The daily maximum number of aphid preyed theoretically by the 1st、2nd、3rd and 4th instar larvae and adult were 16.8,24.0,58.1,84.7 and 76.3 aphids,respectively.The preying action of Propylaea japonica in a certain space was limited by its density.The mutual interference among individual predators and preys could be described by Hassell equation. |
