摘  要:
研究黑缘红瓢虫对朝鲜球坚蚧捕食的功能反应、干扰作用及空间异质性。结果表明 ,其各龄幼虫和成虫功能反应均属于 Holing 型 ,拟合程度较好。黑缘红瓢虫成虫存在着种内干扰 ,其捕食率随着自身密度的增加而降低。空间异质性对黑缘红瓢虫捕食作用有很大的影响 ,捕食者在捕食过程中 ,纸片数越多 ,即环境阻力越大 ,捕食作用率越低

摘  要:
The experiment was conducted to study the functional response,mutual interference and space heterogeneity of Chilocorus rubidus Hope on Didesmococcus koreauus Borchs.The results were as follows:The functional response of different larvae and the adults ladybugs were determined as Holling Ⅱ with better fitting.There was mutual interference among the adults of ladybugs of Chilocorus rubidus Hope,and the predatory rate increased as its density decreased.Space heterogeneity had the great effects on predation.In the course of predation,the predation rate of predator was higher as the environmental obstruction get stronger.
