| 摘 要： | 对中华草蛉与异色瓢虫的幼虫和成虫种间以及各虫态天敌昆虫共存情况下的竞争干扰进行研究.试验结果表明,中华草蛉幼虫与异色瓢虫幼虫竞争干扰明显,在共同捕食时中华草蛉幼虫占优势,成虫间竞争干扰以异色瓢虫捕食蚜虫优势明显大于中华草蛉.2种天敌昆虫各虫态共同捕食蚜虫时高龄幼虫及成虫捕杀低龄幼虫竞争优势明显.

| Abstract: | The competitive interference of inter-species＇ larvae and imagoes between Chrysoperia sinica and Harmonia axyridishad been studied under the condition of co-existence of all natural enemies. The result showed that the competitive interference of the larvae of these two was evident, while the larvae of Chrysoperia sinica had advantage in term of co-hunting for food. With regard to inter-imagoes＇ interference, the hunting of Harmonia axyridisfor aphids was advantage over Chrysoperia sinica. When all insect patterns of these two natural enemies captured aphids, the competitive advantage of both the elder larvae and adult imagoes capturing younger larvae was obvious. |
