引言除了日本的主要岛屿之外，冲绳（琉球）群岛的蜘蛛螨区系与主要岛屿的蜘蛛螨区系不同（Ehara，1966，1995;Gotoh等人，1996).例如，最近描述的一个物种（Ehara，1995年）-冲绳叶螨（Tetranychus okinawanus），迄今为止只在群岛上发现（Takafuji等人，1996;Gotoh等人，1996年）。另一方面，在主要岛屿上常见的物种，如T.urticae和T. kanzawai，也已知来自冲绳（Gotoh等人，1996).群岛位于亚热带地区，因此螨类的生态特征，特别是其滞育特征，将不同于温带地区的螨类。1995年8月，我们在冲绳本岛（冲绳）的不同植物上采集并鉴定了6种叶螨（Gotoh et al.，1996).本文报道了五种叶螨的滞育特性。
INTRODUCTION Being apart from the main islands of Japan,the Okinawa(Ryukyu)Islands have a spider mite fauna which is different from that of the main islands(Ehara,1966,1995;Gotoh et al., 1996).For example,Tetranychus okinawanus,a species recently described(Ehara,1995),so far has been known only from the Islands(Takafuji et al.,1996;Gotoh et al.,1996).On the other hand,species that are commonly found in the main islands,such as T.urticae and T. kanzawai ,are also known from the Okinawa Islands(Gotoh et al.,1996).The Islands are located in the subtropical region,and therefore the ecological characteristics of the mites,in particular their diapause characteristics,will differ from those in the temperate regions. However,no studies on the diapause have so far been published on the populations from the Islands.We collected and identified6species of spider mite from various plants on Okinawa Island,the main island of the group,in August1995(Gotoh et al.,1996).This paper reports the diapause characteristics offive species of the genus Tetranychus.
