二斑叶螨与朱砂叶螨在四季豆上种间竞争力研究

Studies on the Interspecies Competition between Tetraychus urticae Koch and T.cinnabarinus Boisduval fed with Phaseolus vulgaris

对二斑叶螨与朱砂叶螨在以四季豆为寄主时的种间竞争进行了研究。结果表明:无论单种种群还是混合种群,二斑叶螨的活动虫态和成虫的内禀增长力均高于朱砂叶螨,这表明在以四季豆为寄主植物时,二斑叶螨比朱砂叶螨具有更强的种间竞争力。

It was sdudied on the interspecies competition between Tetraychus urticae Koch and T.cinnabarinus Boisduval fed with Phaseolus vulgaris. The results showed that single of T.urticae＇s active mites and matural mites was higher than that of T.cinnabarinus for single species or mixed species.It suggested that the interspecies competition of T.urticae was higher than T.cinnabarinus on the host of Phaseolus vulgaris L..
