摘　　要：在实验室条件下,研究了黑胫突眼隐翅虫幼虫和成虫对不同密度的桃蚜的捕食功能,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、Watt所提供公式作模拟,经卡方检验,其理论值与实测值无统计学差异。The functional response of Stenus macies to its prey, Myzus persicae, and to itsown density was simulated using Holling and Watt models. The functional response ofthe adult and the larve of the predator to the prey and to its own population densitycan be described by the models of Holling and Watt. A X^2 lest showed that thetheoretical expectation fits the observed value (P>O.05).
