| 摘 要： | 天敌对害虫种群的寻找效应是天敌捕食(或寄生)过程中的一种行为特征,亦有人认为是一个物种的行为特性,寻找效应的高低不仅关系到对害虫种群的抑制作用的大小,而且亦关系到天敌自身种群在自然界的繁盛程度。上述情况,无论在实验室内的试验中,田间生物防治实践中,或者在自然群落的结构组成与丰盛度的调查中均已得到证实。因此寻找效应在天敌-害虫系统中作用的重要性,近十多年来,越来越多地受到国内外生态学工作者的重视。

| Abstract: | The searching efficiency on pest population is a kind of behavioural characteristics of natural enemy in the course of predation or parasitism. Both the laboratory experiments and field observations show that the searching efficiency should be regarded as an important element in the structure of natural enemy-pest system. It is usually a function of the pest density, the natural enemy density and the climatic factors. The climatic condi-tons are rarely considered in the literatures published, though their i... |
