Description
Summary:Oriental persimmon, Diospyros kaki Thunb., endemic to East Asia is one of the major fruit cropsin Korea. Recently, spider mite problems on persimmon trees have increased in Korea. Although spider mites are ranked among the most serious pests on fruit trees, little is known about spider mite and predacious mite faunas on persimmon trees. We conducted a faunal survey of mites on persimmon trees in Korea from June to September 2006, especially focusing on herbivorous and predacious mites. Mites of Tetranychidae and Tenuipalpidae were predominantly collected as herbivores, while Phytoseiidae and Stigmaeidae were predominant predators. All identified tenuipalpid mites were Tenuipalpus zhizhilashviliae Reck. Most of the collected tetranychid mites were found to belong to the genus Tetranychus. To clarify the species identity, additional collections of tetranychid mites during summer 2007 on sweet persimmon were made. The mites were identified as Tetranychus urticae Koch. Four phytoseiid species, Neoseiulus womersleyi (Schicha), Amblyseius eharai Amitai and Swirski, Phytoseius (Dubininellus) rubii Xin, Liang and Ke and Typhlodromus (Anthoseius) vulgaris Ehara were collected. Among them, A. eharai was the most dominant species. Two predacious species of Stigmaeidae, Agistemus terminalis (Quayle) and Agistemus lobatus Ehara, also were collected.
