| 摘 要： | 研究了尼氏钝绥螨(Amblyseius nicholsi)对二斑叶螨(Tetranychus urticae)的捕食作用。结果表明,尼氏钝绥螨雌成螨对二斑叶螨卵和成螨是非嗜食的,对幼螨和若螨是嗜食的。尼氏钝绥螨雌成螨对二斑叶螨各螨态的捕食功能反应曲线均为HollingⅡ型,且对幼若螨的捕食作用最大。其自身密度对功能反应存在密度制约作用。

| Abstract: | The predation of Amblyseius nicholsi to Tetranychus urticae was studied.The result showed that A.nicholsi preferred larvae and nymphs rather to other stages of T.urticae.The functional response of female adult of A.nicholsi to different stages of T.urticae could be described with the Holling Ⅱ curve,and A.nicholsi had the biggest predatory capacity to larvae of T.urticae.The density of A.nicholsi had an effect on the predation. |
