    Tick-borne encephalitis (TBE) and Crimean-Congo hemorrhagic fever (CCHF) have been known as tick-borne viral infectious diseases. Recently, severe fever with thrombocytopenia syndrome (SFTS) emerged as a new tick-borne viral infectious disease. TBE is prevalent in Russia and many European countries. CCHF is prevalent in Russia, Central Asia, Europe and Africa. SFTS is now prevalent in China and Japan. This article reviews Tick-borne encephalitis and Crimean-Congo hemorrhagic fever in detail and describe present situation of SFTS.

    Utilizing larvivorous fish is a promising approach to biological control of malaria. In our laboratory, we have tested fish predation ability to Anopheles stephensi larvae under low concentration of copper. We found that at 0.26 ppm larvae were negatively affected, especially in terms of diving ability, which made them easier for the larvivorous fish to catch. This concentration was safe for medaka (Oryzias latipes). It needs further study whether it is possible to use this fish together with low concentrations of copper in the limited area where mosquitoes breed.

    Seasonal occurrence of larval trombiculid mites was surveyed at two adjacent areas using Tullgren's funnel method for three years. Larval trombiculid mites were collected every month from April 2004 to March 2007 at two adjacent areas of Aira City, Kagoshima Prefecture. Twenty trombiculid species were collected from soil samples: Leptotrombidium scutellare, L. kuroshio, L. murotoense, L. kitasatoi, L. himizu, L. fuji, L. miyajimai, L. kansai, Neotrombicula mitamurai, Eltonella ichikawai, Miyatrombicula kochiensis, Cheladonta ikaoensis, Doloisia uchikawai, Helenicula miyagawai, Mackiena todai, Neoschoengastia shiraii, Schoutedenichia nagasakiensis, Walchia koshikiensis, W. ogatai and Gahrliepia saduski. Almost all species were collected in February and March, and only seven species were collected in June and July. L. scutellare was the most abundant in number, followed by L. fuji. Therefore, L. scutellare and L. fuji seemed to be the dominant species in the survey areas. The morphological variation of C. ikaoensis was also observed. The scutum of C. ikaoensis was very wide, especially PW much wider than AW, and variable in the number of first post humeral row of dorsal setae.

    A survey of ectoparasites of roof rats, Rattus rattus and Norway rats, R. norvegicus captured at urban buildings in Tokyo metropolitan and its suburb, from 2008 to 2011 was carried out. Of the 90 roof rats and 6 norway rats examined, 76 (84.4%) and 2 (33.3%) were found to be infested with ectoparasites. Five species of parasitic mites, namely, Ornithonyssus bacoti, Radfordia ensifera, Laelaps nuttalli, L. echidninus and Cheyletus eruditus, and one species of lice, Polyplax serratus, were collected from the roof rats. In addition, no fleas but free living mites, such as Tyrophagus putrescentiae, Lardoglyphus konoi, and Dermatophagoides sp., were also detected from the roof rats.
    Only three species of mites, namely, O. bacoti, R. ensifera and L. nuttalli were detected from 2 (33.3%) out of the 6 Norway rats examined. No fleas nor lice were collected from the Norway rats.

    The collection of Sarcophagidae made by the first author during the surveys on flies of medical and forensic importance in Thailand from 1975 to 2011 is dealt with. A total of 29 genera and 83 species of the flesh flies are listed. Twelve species including Miltogramma iberica Villeneuve, 1912 are newly recorded from Thailand. One new species of the genus Robineauella Enderlein is described and illustrated, which is similar to Robineauella coei Rohdendorf, 1966 from Nepal and the widespread species R. pseudoscoparia (Kramer, 1911) in general appearance. Revised identification keys to the Thai species are provided including a new and newly recorded ones.
