| 摘 要： | 以斜纹夜蛾Spodoptera litura幼虫为寄主,观察了不同补充营养处理（饥饿、饲喂清水、饲喂30%糖水）和寄主密度等因素对斑痣悬茧蜂Meteorus pulchricornis的搜寻效率和寄生选择行为的影响。结果显示,不同寄主密度对斑痣悬茧蜂的搜寻效率和选择偏好有显著影响,寄生蜂明显倾向于选择高密度寄主斑块。未发现补充营养显著影响斑痣悬茧蜂的搜寻时间,说明补充营养对斑痣悬茧蜂的搜寻效率没有显著影响,但对其寄生的寄主数量具有显著影响,在5头.叶-1与15头.叶-1的寄主斑块之间具有显著差异。

| Abstract: | Experiments were conducted to evaluate effects of supplementary foods（no food,only water,and 30% g·L-1 sugar solution） and host density on foraging efficiency and parasitization selection behavior of Meteorus pulchricornis for Spodoptera litura larvae.Results indicated that host density had significant effects on foraging efficiency and selection for host patches with an obvious preference for high host-density patches.The supplementary foods tested did not affect foraging time,which suggested no significant influence on foraging efficiency,but they had influence on parasitism,which was significant when the paired-patch of 5 and 15 larvae per leaf was exposed to parasitism. |
