    Myiasis in Japan was reviewed based on the case reports published until 2014. A total of 209 cases of facultative myiases were reported and these involved more than 32 species from 11 dipteran families. Boettcherisca peregrina, Lucilia sericata, and Parasarcophaga similis were responsible for 74 of all the cases. Four foreign dipteran species were involved in 50 cases of obligatory myiasis. Dermatobia hominis imported from Central and South America dominated with 41 of these cases. Four cases of wound myiases were caused by L. sericata and L. ampullacea, and one case of ophthalmomyiasis by B. peregrina was acquired in forests or similar environments. Among the flies known as forest-dwelling species, L. ampullacea, Chrysomya pinguis, and B. septentrionalis are found to be dominant in forests. It is recommended that people visiting forests stay together and avoid exposing their skin to prevent infections from myiasis-producing flies. For development of control measures to reduce infections, it is essential to accumulate knowledge on the abundance of myiasis-producing flies in different forest environments and on smaller islands, and to collect case reports of human myiasis with reliable identifications of the fly species involved.

    Previous records of Sri Lankan Anopheles were most imperfect, and even the number and names of the species present were very doubtful. There was no systematic study conducted for Sri Lankan adult anophelines since 1990. Therefore, the objective of this study was to explore the species abundance and morphological variations of anopheline mosquitoes in Sri Lanka. Entomological surveys were conducted on a monthly basis from June 2010 to December 2013 in Trincomalee District, using five entomological techniques. Entomological surveys identified a total of 131,804 mosquito specimens belong to 18 anopheline species. One of which was An. jeyporiensis, a species that was not in the checklist in Sri Lanka. Its basic morphological features are similar to the members in Myzomyia series under the subgenus Cellia. Following characteristics were used to confirm the species as An. jeyporiensis; Centre of the scutum covered with short oblong white scales extending back to scutellum; Vein R1 usually with accessory pale spot on preapical dark (PD) area; Foretarsomere 1 with apical pale band nearly 2.0 width of tarsomere diameter.

    The immature distributions and breeding habitats of the vector mosquito, Culex vishnui Theobald, of Japanese encephalitis virus, and other species of the Culex Vishnui Subgroup, in paddy fields, fallows and other sites were examined from 2004 to 2008 in five islands of the Ryukyu Archipelago, Japan. Culex vishnui was found in three islands, Okinawajima, Ishigakijima and Iriomtejima, but it was not collected from the two northern islands, Amamioshima and Iheyajima. The greatest percentage of positive breeding pools with Cx. vishnui was significantly higher in Ishigakijima (68.8%) and Iriomotejima (43.7%), compared with Okinawajima (19.0%). Culex vishnui was the dominant species collected from Iriomotejima, while Cx. tritaeniorhynchus Giles was the most abundant species collected from the other four islands. Culex vishnui shared same paddy fields and fallows with Cx. tritaeniorhynchus and Cx. pseudovishnui Colless in Ishigakijima and Iriomotejima. In Amamioshima, Cx. pseudovishnui was commonly associated with Cx. tritaeniorhynchus in paddy fields.
