摘要
在室内条件下研究了烟盲蝽5龄若虫对朱砂叶螨卵、幼若螨和成螨的捕食效能。结果表明,不同虫态不同密度分布对烟盲蝽5龄若虫的捕食效能有一定的影响。烟盲蝽5龄若虫对朱砂叶螨的卵、幼若螨和成螨的捕食反应为Holling Ⅱ型;增加空间异质性烟盲蝽5龄若虫捕食朱砂叶螨成螨的反应仍为Holling Ⅱ型。建立的模拟方程显示烟盲蝽5龄若虫对不同虫态的朱砂叶螨理论捕食量与实际捕食量吻合。
The predation efficiency of 5 - instar Nesidiocoris tenuis on egg, nymph and adult of Tetranychus cinnabarinu was studied in laboratory. The results indicated that the functional response of Nesidiocoris tenuis to Tetranychus cinnabarinu was Holling Ⅱ type both in petri dish and glass cylinder. The density of Tetranychus cinnabarinu played an important role on the predation efficiency. The simulation equation showed that the predation amount of 5 - instar Nesidiocoris tenuis on Tetranychus cinnabarinu agreed well with the theoretical amount.
