Mite diversity of selected citrus orchards in Andalusia (southern Spain) was studied during 2002-2007. The following species were found: Eutetranychus orientalis, Tetranychus urticae, Panonychus citri (Tetranychidae), Tydeus californicus, Lorryia formosa (Tydeidae), Pronematus ubiquitus (Iolinidae), Euseius stipulatus, Typhlodromus phialatus, Neoseiulus californicus, Euseius scutalis, Phytoseiulus persimilis, Paraseiulus talbii and Neoseiulus cucumeris (Phytoseiidae). Eutetranychus orientalis was the dominant tetranychid species in orange and lemon trees, whereas T. urticae was slightly more abundant in mandarines. The most abundant tydeid in clementine and orange was Tydeus californicus, in lemon it was L. formosa. The iolinid P. ubiquitus was found in very low numbers. With respect to phytoseiids, E. stipulatus was dominant in the three citrus species. Eutetranychus orientalis had a unimodal phenology, peaking only in autumn, whereas the other two tetranychids had two maxima. Tydeus californicus showed one or two peaks depending upon the citrus species, and E. stipulatus also had two peaks, one in spring and one in autumn. The mites displayed a non-random distribution in the tree. Eutetranychus orientalis preferred the outer and upper leaves. On the contrary, tydeids (mainly T. californicus) and phytoseiids (mainly E. stipulatus) preferred inner and lower leaves. These preferences had not been sufficiently described previously, and they are important for sampling plans.
2002年至2007年期间，对西班牙南部安达卢西亚选定柑橘园的螨类多样性进行了研究。发现了以下物种：东方真叶螨、二斑叶螨、柑橘全爪螨（叶螨科）、加州钝绥螨、美丽罗里螨（跗线螨科）、普遍原伊螨（伊螨科）、斯氏钝绥螨、肩毛钝绥螨、加州新小绥螨、盾片钝绥螨、智利小植绥螨、塔尔比副绥螨和黄瓜新小绥螨（植绥螨科）。东方真叶螨是橙子树和柠檬树中占主导地位的叶螨物种，而二斑叶螨在柑橘中数量略多。在克莱门氏小柑橘和橙子中最丰富的跗线螨是加州钝绥螨，在柠檬中是美丽罗里螨。普遍原伊螨数量极少。关于植绥螨，斯氏钝绥螨在这三种柑橘品种中占主导地位。东方真叶螨的物候呈单峰型，仅在秋季达到峰值，而其他两种叶螨有两个峰值。加州钝绥螨根据柑橘品种显示出一个或两个峰值，斯氏钝绥螨也有两个峰值，一个在春季，一个在秋季。螨类在树上呈非随机分布。东方真叶螨更喜欢外部和上部叶片。相反，跗线螨（主要是加州钝绥螨）和植绥螨（主要是斯氏钝绥螨）更喜欢内部和下部叶片。这些偏好此前未得到充分描述，对抽样计划很重要。
