摘要
为探明南方小花蝽(Orius similis)对西花蓟马(Frankliniella occidentalis)的控制潜能,进行了不同寄主植物下南方小花蝽对西花蓟马捕食的功能反应及寻找效应的研究。结果表明,南方小花蝽在5种寄主植物上对西花蓟马的捕食量大小关系依次为菜豆>辣椒>茄子>黄瓜>番茄,南方小花蝽对西花蓟马的功能反应均符合HollingⅡ圆盘方程。以瞬时攻击率和寻找效应为评价指标发现,南方小花蝽在菜豆和辣椒上的瞬时攻击率(a')最高,分别为1.048 9和0.860 5,寻找效应较好;在黄瓜和番茄上的瞬时攻击率(a')最低,分别为0.7199和0.5687,寻找效应较差。
The functional response and searching efficiency of O. similis to F. occidentalis were studied at five kinds of host plants to approach the controlling effect of O. siznilis to F. occidentalis. The results showed that the predation of O. similis to F. occidentalis on five kinds of host plants followed by common bean〉 pepper 〉eggplant〉 cucumber〉 tomato. The functional responses of O. sirnilis to F. occidentalis fitted by Holling Ⅱ＇s equation. Taking instantaneous attack rate and searching efficiency as evaluation indicators, it was found that the instantaneous attack rate was maximum on common bean and the pepper for 1. 0489 and O. 8605 respectively on the cucumber and the tomato for 0. 719 9 and , and the searching efficiency was good. It was minimum O. 568 7 respectively, and the searching efficiency was
