Studies on the biology of predacious phytoseiid mites in Japan were reviewed. At least 135studies were published by Japanese acarologists between 1974and 1997which constitutes 15.6%of all studies in the field of agricultural acarology. Most research on domestic species focused on their biological capacity and efficiency as natural enemies of spider mites. However, no species were successfully mass-produced and commercially available. Both basic and applied studies of domestic species are currently needed because public interest in phytoseiid mites as a biocontrol agent of spider mites is increasing. Key words: Phytoseiidae, predacious mites, biological control, spider mites

In the years of1995andl996, a total of6, 802ticks were collected by flagging on vegetation at50sites in the mainland of Kagoshima Prefecture, Japan. These were identified as three genera and10species as follows: Amblyomma testudinarium, Haemaphysalis flava, H. formosensis, H. hystricis, H. kitaokai, H. longicornis, H. megaspinosa, Ixodes nipponensis, I. ovatus and I. turdus. The most abundant and widely distributed species was H. flava, followed by H longicornis and H. formosensis. In isolaton of rickettsiae by using cultured L-929cell, three nymphal A. testudinarium were positive for spotted fever group rickettsiae of the AT-1serotype(near Rickettsia massiliae), and seven adult I. ovatus were found positive for the same group rickettsiae of theIO-1 serotype(Rickettsia helvetica-like), and trypanosome-like protozoa was detected in one nymphal A. testudinarium.

The oribatid fauna in Ozegahara, Central Japan, was surveyed in relation to vegetation type and soil water content. Thirty six oribatid faunae under7vegetation types comprised175species which were classified into four groups based upon the quotient of similarity(Sø rensen). Two notable features of the faunae in Sphagnum communities which is the main vegetation in Ozegahara were that: 1)the number of species decreased with soil water content; 2)many species present belong to the Crotonioidea. Characteristic species in Ozegahara were the following hygrophilous species: a)Limnozetes rugosus, Hydronothrus crispus, Trimalaconothrus sp. 1and Hydrozetes terrestris in a submerged area; and b)Limnozetes ciliatus, Trhypochthoniellus setosus and Rostrozetes ovulum on a high moor. Microdistribution of these species were different from one another in relation to soil water content.

A new species of the genus Bakerdania Sasa, 1961(Acari, Pygmephoridae)is described and illustrated from Japan under the name of B. nicrophori. It is known from the adult female and found attached to the membrane between pro- and mesothorax of the burying beetle, Nicrophorus concolor Kraatz. This new species closely resembles B. decumanus decumanus(Krczal, 1959)from Europe and B. decumanus gobiensis(Mahunka, 1969)from Mongolia, but is distinguished from them by the relative length of some dorsal body setae. Further, B. nicrophori differs from B. d. decumanus in the shape and position of stigma, the position of body seta h1 relative to h2, and the shape of apodeme IV and claw of leg I.
