摘要： 拟水狼蛛的捕食功能反应是随猎物密度的增加而增大;而随其本身密度的增大而减少。它对叶蝉的捕食量大于飞虱,对成虫的捕食量大于若虫。数学模拟的理论值与观察值很接近,经X²检验后,误差不显著(<P0.05)。

Abstract: Functional response of Plrata subpiraticus to its prey density waa found to be poaaitively correlated with the prey density, and negatively correlated with its own density. As a prey, leafhopper waa preferred by P. aubpiraticua to planthopper. According to Holling and Watt\'s equations, the functional response of the predator to leafhoppera and planthoppera can be described in the following equations:(1) Na=0.863No/(1+0.0515No)(2) Na=0.705No/(1+0.0259No)(3) A=5.627P-0.674(4) A=4.925P-0.6874The theoratical value examined with X²was very close to the observed value <P=0.05).
