    House dust mites are known as one of the important agent of allergic disease, and most insect-borne dermatitis is considered to be caused by some house mites. The frequency of mite caused problems in Japanese homes has been increasing. Therefore, in this paper, the house dust mites collected from residences in various places in Japan were reviewed. As a result of the survey of various places in Japan between 1964 and 1997, 135 species of mites were detected from house dust, and common species of those mites counted 50 species belonging to Astigmata, Prostigmata, Mesostigmata and Cryptostigmata. The pyroglyphid mites, two species of Dermatophagoides pteronyssinus and D. farinae were the most common mites. Of the other mites, Acaridae, Winterschinidtiidae, Glycyphagidae, Chortoglyphidae, Histiostomatidae, Cheyletidae, Tarsonemidae, Bdellidae, Cunaxidae, Tydeidae, Tetranychidae, Tenuipalpidae, Raphignathoidae, Ascidae, Ameroseiidae, Phytoseiidae, Laelaptidae, Haprochthoniidae, Cosmochthoniidae, Oribatulidae and Protoplophoridae were notable. In addition, mite fauna and population were shown to change under variuous conditions; indoor, outdoor, environment, life-style and so on.

    In a Prostriata, Ixodes ovatus Neumann (Acari: Ixodidae), the fate and ultrastructural changes of male germ cells were observed during their reproductive behavior including copulation and feeding. Before copulation, male germ cells in the male seminal vesicle were prospermia. After copulation, the timing of spermateleosis and ultrastructural changes during spermateleosis were the same as those in other ixodids. In I. ovatus, endospermatophores were fragmented in the cervical vagina, although they occur within the receptaculum seminis in Metastriata. After fragmentation of endospermatophores, the male germ cells reached a common oviduct, where they were stored for at least 30 days. On day 30 after copulation, the ultrastructure of the male germ cells in the common oviduct was the same as on day 2 after copulation. On the other hand, the male germ cells reached the oviducts on day 4 after engorgement (corresponding to day 9 after copulation). This indicates that feeding advances ascent of male germ cells.

    Paraphytoseius cracentis (Corpuz and Rimando) was recorded from Japan for the first time. A redescription of P. cracentis, based on Japanese material, was given, and notes on P. multidentatus Swirski and Shechter were also included.

    Two macrochelid species were collected from the body surface of Trox sugayai (Coleoptera: Trogidae) on Amami-Oshima Island, Japan. One of them is described as new to science under the name Macrocheles amamiensis. This new species is very similar to some congeners previously recorded from Trox beetles, but is clearly distinguished by the ornamentation and setae of dorsal and sternal shields.

    The present work deals mostly with the members of primitive or macropyline (Macropylina) and a few higher or brachypyline (Brachypylina) oribatid mites from Yazd Province, Central Iran. Two new species, Anomaloppia iranica sp. nov. and Ramusella abarkouhiensis sp. nov. are described. In addition, supplementary descriptions of eleven known species are given, which are recorded for the first time from this country. Data on geographic distribution of each known species are given.

    The male accessory genital glands of Haemaphysalis longicornis are a complex of glands consisting of the single dorso-median and medio-ventral lobes and paired antero-ventral, latero-ventral, dorso-lateral, postero-lateral, and postero-ventral lobes. The epithelia of each lobe produce various secretory granules during feeding and these secretions have important functions in the formation of the spermatophore. Some of the accessory gland secretions form the spermatophore as a bag of male germ cells, and others are packed in the spermatophore and then transferred into the female genital tract. The fate of the accessory gland secretions was elucidated by comparison between the ultrastructure of the male accessory genital glands and the spermatophore, and the roles of these secretions are discussed. The characteristic fine structures of each lobe and 24 types of secretory granules were observed in the whole accessory glands. It was shown morphologically that two layers of the ectospermatophore were derived from the antero-ventral and postero-lateral (=dorso-lateral) lobes and three types of granular contents in the spermatophore from the postero-ventral, latero-ventral and medio-ventral lobes. These findings support the results of histochemical previous observations, and more accurate information on the derivation of substances in the formation of the spermatophore were obtained.

    The present work deals with some members of poronotic oribatid mites from Iran. A new species, Baloghiella granulata sp. nov. is described from Yazd Province, Central Iran. In addition, supplementary descriptions of seven known species are given, which are recorded for the first time from this country. The following new combination is proposed: Protoribates paracapucinus (Mahunka, 1988) comb. nov. Data on geographic distribution of each known species are given.

    Two new methods were developed to estimate the population densities of the rust mite (Eriophyes chibaensis Kadono) on Japanese pear. In the sticky tape method, transparent, sticky tape was rubbed onto the underside of the pear leaf, and the mites sticking to the tape were counted under stereomicroscopy. In that case, mites sticking to the tapes were clearly estimated by using colored paper of green, black or brown as the colore of background of the tapes. In the water-sensitive paper method, the tape with captured mites was pressed against water-sensitive paper, and mite density was roughly estimated by the quantity of blue spots on the paper. These methods were considered to be useful and effective enough to estimate rust mite populations.
