This review serves to summarize important articles concerned with acari-borne rickettsioses and spirochetoses inside and outside of Japan, especially from the acarology researcher's side, and to introduce recent findings, or to deal with as many questions as possible including our preliminary results. The subjects herein presented are as follows; vectorial competences of trombiculid mites for tsutsugamushi disease associated with regional endemic factors throughout Japan, vectorial competences of ticks for spotted fever occurring in the southwestern half of Japan and any possible vectors of other rickettsioses known recently; vectorial competence of ticks for Lyme disease found mostly in the northeastern half of Japan and various questions on the transmission dynamics of Borrelia.

Two species of swimming pool mites, Hydronothrus crispus (Hc; Cryptostigmata, Trhypochthoniidae) and Schwiebea sp. (Sch; Astigmata, Acaridae) were cultured in vitro, and their allergenicities were investigated by RAST using sera obtained from 32 swimmers and 43 randomly selected, healthy non-swimmer athletes. Positive rates for Sch-, Hc-, and Dermatophagoides farinae (Df; Astigmata, Pyroglyphidae)-RAST was 28.1,25.0 and 59.4% in swimmers, and 31.8,31.8 and 63.6% in non-swimmers, respectively. Both Hc- and Sch-RAST reactions were similarly inhibited by the addition of Sch, Hc and Df antigens. Df-RAST was inhibited by Df itself but not by Sch and Hc antigens. And the RAST values were highly correlated with each other. These facts indicate that there are strong antigenic cross-reactivities among Sch, Hc, and Df. From these results, the author concludes that the swimming pool mites have active allergenic components, which are common with those of Df.

The movement and oviposition of Aedes albopictus were examined by a combination of mark-release-recapture experiment and an ovi-trap survey of egg numbers in Nagasaki, Japan. Fed mosquitoes were marked with fluorescent dye and released into an isolated, small, grassy and scrub area on the campus of Nagasaki University School of Medicine. Twenty ovi-traps were distributed evenly in the study area and the number of eggs was examined for 2 weeks and 9 days before and after the release, respectively. Human bait collections were made at 10 collection points also in the same period. The multiple regression analysis was applied to the observed differences in egg density among ovi-traps after the release and those in recaptured mosquitoes. The baseline data collected before the release were used as independent variables. The results showed a high correlation between the number of eggs deposited in an ovi-trap and the distance from the release point to the ovi-trap. The number of recaptured females in a collection site showed a high correlation with the distance from the release point during the first 2 days after the release. However, on the 4-5th day after the release, the number of recaptured females showed a higher correlation with the number of unmarked females.

Two new calliphorid flies are described from Thailand, namely Dexopollenia yuphae sp. nov. and D. fangensis sp. nov., which are characteristic with crinkly golden hairs on thorax. Male genitalia are illustrated. A key to all the known species of the genus Dexopollenia from the Oriental region is given.

The common method of isolation of house dust mites from house dust has been done by using 0.075 mm-mesh sieve. In the present study, we tried to isolate house dust mites, especially Tarsonemid mites, by using 0.053 mm-mesh sieve in addition to 0.075 mm-mesh sieve, and the isolation efficiency was compared with that using 0.075 mm-mesh sieve only. As the result, 78.4% of Tarsonemid mites was found on the 0.053mm mesh, and the total number of Tarsonemid mites was far different from the number of mites on the 0.075mm mesh. Tarsonemid mites were also found in high rates (12.9-39.5%) in the houses surveyed in this study.

The long-term effects of sublethal concentrations of fenoxycarb [ethyl 2-(4-phenoxyphenoxy) ethylcarbamate] were studied against mosquitoes by treating late third instar larvae of Culex quinquefasciatus Say and Culex pipiens molestus Forskal (laboratory colonies) under laboratory conditions. The sublethal effects of fenoxycarb demonstrated a significant relation between concentration and cumulative mortality. Fenoxycarb, when applied at 0.0025-0.05ppb, induced long-term sublethal effects as indicated by the significantly reduced egg hatchability and survival of the different stages (larva, pupa and adult) in the offsprings of Cx. p. molestus. No similar long-term effects were observed in Cx. quinquefasciatus.

A twelve-month study was initiated to determine the presence and species composition of mosquitoes breeding in the septic tanks in the University of Mosul, north of Iraq (latitude 36°N) during the period of June 1988-June 1989. Based on the identification of male genitalia and ratio of female autogeny, this study revealed that Culex quinquefasciatus Say and Culex pipiens molestus Forskal breed together in the same septic tanks. In the fall and winter months (October-January), larvae and pupae of Cx. p. molestus were more abundant than those of Cx. quinquefasciatus. The presence of Cx. quinquefasciatus in Mosul (northern Iraq) is the first record.

The fauna and distribution of the blackflies in Shimane Prefecture were investigated by collecting larvae and pupae of blackflies from streams in 68 localities in the spring of 1991. A total of 7,218 larvae and 1,612 pupae belonging to 2 genera (Prosimulium and Simulium) and 18 species were collected at 67 sites. Seven species, Simulium (Nevermannia) konoi, S. (Simulium) quinquestriatum, S. (Gnus) daisense, S. (Gomphostilbia) omutaense, S. (Gom.) ogatai, S. (N.) mie, and S. (Eusimulium) sp. H. were newly recorded from Shimane Prefecture. The predominant species was S. (Gn.) bidentatum (26 9%), followed by S. (N.) uchidai (26.1%), S. (S.) arakawae (12.0%), S. (N.) konoi (9.7%) and S. (Odagmia) aokii (6.9%). The most widely distributed species were S. (N.) uchidai (53 sites), S. (G.) bidentatum (44 sites), S. (S.) japonicum (37 sites), S. (N.) subcostatum (27 sites), S. (S.) arakawae (25 sites) and S. (O.) aokii (25 sites).

It was found that original descriptions of Simulium kawamurae Matsumura and S. arakawae Matsumura were published in Dai Nippon Gaichu Zensho, Vol. 2,1st. ed., pp. 84,85 (1915) respectively. The commonly cited Dai Nippon Gaichu Zensho (1921) was the 3rd edition.

The molting percentages of the non-diapausing and diapausing groups of engorged I. persulcatus larvae and nymphs were compared after exposure to a low temperature (-5℃) for 1-50 days. The molting percentages of the engorged larvae and nymphs decreased as the duration of the treatment was prolonged. In both engorged larvae and nymphs, there was no great difference in the molting percentage between the non-diapausing and diapausing groups. This suggests that the increase of the cold tolerance by diapause did not occur in engorged I. persulcatus larvae and nymphs.
