本文研究了樟树叶腹叶及邻近腹叶的捕食性叶螨Amblyseius sojaensis的季节发生规律。6月份叶蝉数量增加，其次是大豆根结线虫数量增加。当有绿叶螨存在时，靠近口端的大豆按蚊数量显著高于无叶面时的数量。用胶水充填家蝇入口处以防止被捕食，大豆田鼠密度显著降低。这些结果表明，栖息在家蝇上的绿叶螨密度影响着不在家蝇上栖息的捕食性叶螨的密度。
We studied the seasonal occurrence of the eriophyid mites in the domatia of Cinnamomum camphora leaves and the predatory mite, Amblyseius sojaensis, near the domatia. The eriophyid mites increased in number in June, followed by an increase of A. sojaensis. The number of A. sojaensis near the domatia was significantly higher when the eriophyid mites were present in the domatia than when they were absent from it. When the domatia entrance was experimentally filled with glue to prevent the eriophyid mites from being preyed upon, the density of A. sojaensis was significantly reduced. These results showed that the density of the eriophyid mites that inhabit the domatia affect the density of the predatory mite, A. sojaensis, that do not inhabit the domatia.
