| 摘 要： | 为明确蠼螋对草地贪夜蛾的捕食作用，在温度（26±1）℃，相对湿度（75±5）%，光周期16L：8D的实验室条件下，观察了蠼螋5龄若虫对草地贪夜蛾卵、1~6龄幼虫和成虫的捕食行为和对6龄幼虫的捕食功能反应。结果表明：蠼螋5龄若虫对草地贪夜蛾卵和1~6龄幼虫均有捕食行为，对飞行能力弱的草地贪夜蛾成虫也具有捕食能力。蠼螋5龄若虫对草地贪夜蛾捕食过程中，并不取食完其整个虫体，而是咬食至猎物不动时，继续搜索捕食周围其他猎物。蠼螋5龄若虫对草地贪夜蛾6龄幼虫的捕食功能拟合HollingⅡ模型，日平均捕食量为2.85头，对入侵的草地贪夜蛾的为害具有一定的防控潜能。

| Abstract: | Predation of Labidura riparia Pallas preying on Spodoptera frugiperda was investigated by observing the predatory behaviors of 5th instar nymphs of L. riparia to the eggs and 1―6th instar larvae and adults of S. frugiperda and measuring the predation functional response of 5th instar nymphs of L. riparia to 6th instar larvae S. frugiperda at the conditions of (26±1) ℃, (75±5)% RH and a photoperiod of 16L:8D. The results demonstrated that the 5th instar nymphs of L. riparia showed strong predation capacity to the eggs, larvae and even the flightless adults of S. frugiperda. When L. riparia preyed on S. frugiperda, L. riparia did not eat up S. frugiperda completely; instead, L. riparia bited S. frugiperda until the preys could not move and then transferred to attack other preys. The predatory functional response of the 5th instar nymphs of L. riparia to 6th instar larvae S. frugiperda fitted well with Holling II model, with average preying number of 2.85 per day. L. riparia can be used as a potential local natural enemy to control the invasive pest S. frugiperda in the future. |
