摘要
通过对稻粉虱Aleurooybotus indicus及其天敌时间生态位和空间生态位的调查,测定了生态位宽度、生态位重叠和生态位比例相似性。在此基础上,构建时空二维生态位,并分析了稻粉虱及其天敌的发生规律和相互关系。
The niche breadth , the niche overlap , the proportional similarity of niche of Whitefly and its natural enemies were estimated by means of investigating their single dimension-al temporal niches and spatial niches, basing on which the two dimensional niches of time and space niches were constructed, the occurrence law and mutual relation were analysed.
