| 摘 要： | 室内观察测定了中华草蛉3龄幼虫对西花蓟马的捕食功能反应和搜寻效应。结果表明,26℃条件下该捕食功能反应符合HollingⅡ型方程。随着猎物密度的增加,中华草蛉3龄幼虫对西花蓟马成虫、若虫的捕食量增加,搜寻效应降低,捕食上限分别为625.0头/d和714.3头/d。 |
| 关 键 词： | 中华草蛉 西花蓟马 捕食作用 |

| Abstract: | The functional response and searching rate of 3-instar Chrysopa sinica larvae on Frankliniella occidentalis were studied in laboratory.The results showed that the functional response could be described with Holling II equation at 26℃.The predation capacity of 3-instar C.sinica larvae on F.occidentalis adults and larvae increased with the increasing density of F.occidentalis,but the searching rate decreased.The maximal predation was 625.0 individual and 714.3 individual per day,respectively. |
| Keywords: | Chrysopa sinica Frankliniella occidentalis Predation |
