Abstract: The functional response of Propylaea japonica Thunberg (Coleoptera: Coccinellidae) to five densities of Acyrthosiphon pisum Harris (Homoptera: Aphididae) was investigated by disc method under growth chamber condition, in order to understand the controlling capability of P. japonica to A. pisum. Plotting prey density against prey killed by four larval instars, adult males and females of Propylaea japonica fit well with the typeⅡ model of Holling’s disc equation. Adult females consumed the highest number of the prey, followed by fourth instars and adult males. Based on the functional response data, the model predicts a maximum of 6.5, 20.4, 32.3, 71.4, 58.8, and 80.0 nymphs to be consumed per day by individual first, second, third instar, adult male, fourth instar, and adult female, respectively. The results indicated the predation of P. japonica on A. pisum was greater.

摘要: 为了解龟纹瓢虫(Propylaea japonica)控制豌豆蚜(Acyrthosiphon pisum)的能力,在实验室内采用圆盘法测定了不同龄期龟纹瓢虫对豌豆蚜的捕食功能反应,以期掌握龟纹瓢虫控制豌豆蚜的能力。结果表明:龟纹瓢虫4个龄期的幼虫和雌雄成虫捕食豌豆蚜的数量与豌豆蚜密度呈负加速曲线关系,符合Honing-Ⅱ型功能反应模型。龟纹瓢虫雌成虫的日捕食量最大,其次是第4龄幼虫和雄虫。模型预测了龟纹瓢虫1,2,3,4龄幼虫及雄、雌成虫对豌豆蚜的日最大捕食量分别是6.5,20.4,32.3,71.4,58.8,80.0头。综上所述,龟纹瓢虫对豌豆蚜有较强的控制能力。
