苹果（Malus domestica Borkh.）在20±0.5°C、15 L：9D光周期、90± 5%RH条件下，调查了未喷洒杀虫剂或杀螨剂的树木上叶螨和植绥螨的发生情况，并研究了植绥螨的捕食特性，以寻找适合日本防治苹果全爪螨的家养植绥螨。在苹果树上发现沃氏钝绥螨Amblyseius womersleyi Schicha、津川钝绥螨Amblyeseius tsugawai Ehara和普通盲走螨Typhlodromus vulgaris Ehara，它们寄生于苹果树上的榆实蝇和二斑叶螨Tetranychus urticae Koch。在采集的植绥螨中，T.在榆上饲养时，黄姑鱼的发育率为75%，雌虫率为67%。交配后的雌性T.梨小食心虫幼虫和成虫取食后均产卵。相反，T.普通白榆既不消耗猎物，也不发育，交配后的雌性白榆饲养时，喂养T。荨麻疹因此，T.在减少喷雾量的条件下，小实蝇是抑制苹果园梨大实蝇种群的有效捕食者。
Apple (Malus domestica Borkh.) trees that had not been sprayed with either insecticides or miticides were explored for the occurrence of tetranychid and phytoseiid mites, and predatory characteristics of the phytoseiid mites were investigated in the laboratory at 20±0.5°C, with a 15L : 9D photoperiod and 90±5% RH, to find an appropriate domestic phytoseiid predator for controlling Panonychus ulmi (Koch) in Japan. Amblyseius womersleyi Schicha, Amblyeseius tsugawai Ehara and Typhlodromus vulgaris Ehara were found on apple trees inhabiting P. ulmi and Tetranychus urticae Koch. Among phytoseiid mites sampled, T. vulgaris showed a favorable developmental ratio of 75% with the female ratio of 67%, when reared on P. ulmi. Mated females of T. vulgaris laid eggs when fed larvae and adults of P. ulmi. On the contrary, immature stages of T. vulgaris neither consumed prey nor developed, and mated females reared on P. ulmi laid no eggs when fed T. urticae. Therefore, T. vulgaris was expected to be an effective predator for suppressing the P. ulmi population in apple orchards under reduced spray programs.
