研究了南方小花蝽 (Oriussimiliszhong)各龄若虫在不同烟蚜密度下的捕食量与其发育速率的关系。结果表明 :在一定范围内 ,南方小花蝽各龄若虫的捕食量与其发育速率均为线性关系 ,符合Beddington模型。南方小花蝽各龄若虫的捕食量与产卵量也呈近线形关系。
The relationship between the predation rate and the developmental rate of each instar nymphs in Orius intermedius at different density of aphids was studied. The results showed that: within a certain range, the predation amount and developmental rate of each instar nymphs of S. niger were linear, which accorded with Beddington model. The predation amount and spawning amount of Nymphis nymphaea in each instar also showed a nearly linear relationship.
