| 摘 要： | 目的]了解烟盲蝽5龄若虫对菜蚜低龄若蚜的捕食能力。方法]在试验室条件下,分别研究了培养皿中和小纱筒中烟盲蝽5龄若虫对6个密度菜蚜低龄若蚜的捕食功能反应,并对烟盲蝽5龄若虫自身密度的干扰效应进行了观察。结果]烟盲蝽5龄若虫对低龄菜蚜的捕食功能反应可用HollingⅡ型圆盘方程拟合。其自身密度对捕食作用的干扰效应符合Hassel-Verley的干扰效应模型。结论]烟盲蝽5龄若虫对低龄菜蚜的捕食量随猎物密度的不同而有较大差异,烟盲蝽5龄若虫自身密度对功能反应存在密度制约作用。

| Abstract: | Objective] The research aimed to know the predation efficiency of 5th instars of Nesidiocoris tenuis on nymph of vegetable aphids.Method] With N.tenuis 5th instars as tested insect source,6 densities of vegetable aphid were set up to study the predacious functional response of N.tenuis to vegetable aphids.Result] All the functional responses of N.tenuis to vegetable aphids could be fitted with HollingⅡdisc equation both in petri dish and glass cylinder.The disturbance effect of self density of N.tenuis 5th instars on predacious function was obvious,which accorded to the Hassel-Verley model of disturbance effect.Conclusion] The predation of 5th instars of N.tenuis on vegetable aphid had bigger difference.And the index of predatory functional response was also depended on density of N.tenuis. |
