摘要
本文详细地研究了桔全爪螨 Panonychus citri 与其天敌尼氏钝绥螨(以下简称尼氏螨)A.nicholsi 之间的数量关系(包括功能反应和数值反应)。主要结果如下:1.尼氏螨对桔全爪螨的瞬时攻击率在其孵化后第五天达到最大值。其功能反应更接近于Holling Ⅰ型。2.当桔全爪螨的密度为每 Munger 小室内9头时,尼氏螨的产卵量和内禀增殖率是最大的。3.当尼氏螨仅靠捕食桔全爪螨来维持生命时,其寿命和产卵量远远低于它取食花粉时的情况。
The quantitative relationships(including the functional response and the nu-
merical response)between the citrus red mite,Panonychus citri,and its natural
enemy,Amblyseius nicholsi,are studied in detail in this paper.The main results
are as follows:
1.The instantaneous attack rate of A.nicholsi against the citrus red mite,
Panonychus citri,is maximum on the fifth day after the emergence of A.nicholsi,
and the functional response tends to the type of Holling Ⅰ. 2.When the density of citrus red mite is nine adult or larval mites per Mun-
ger room,the egg number and intrinsic natural increase rate of A.nicholsi are
maximum.
3.When citrus red mite is only food resourse of A.nicholsi,the longevity
of A.nicholsi isvery short,and its egg number is very low.
