| 摘 要： | 在实验室的条件下,研究了脊胸小头隐翅虫 Philonthus rutiliventris Sharp成虫对不同密度桃蚜的捕食功能,以及捕食者自身密度对捕食作用的影响。根据试验所观测的捕食量,分别按 Holling及 Watt 公式作模拟,经卡方检验,其理论值与实测值无统计学差异。

| Abstract: | The functional response of Philonthus rutiliventris Sharp to its prey and to its own density was investigated using Moiling and Watt models. The functional response of the adult of the predator to the prey and to its own population density can be described by models of Holling and Watt. A X2 test showed that there is no statistic difference between the theoretical expectation and the observed value. |
