    We monitored vector mosquitoes and arboviruses to clarify the vector mosquito population dynamics and the prevalence of viral possession. We collected 760 mosquitoes at five locations in Ishikawa Prefecture, Japan, in 2019. Aedes albopictus (Skuse) (Diptera: Culicidae) accounted for 73.3% of all mosquitoes collected, representing a high proportion for July to September. Moreover, the number and proportion of Ae. albopictus collected varied depending on location. RNA extracted from female Ae. albopictus was tested for Dengue, Chikungunya, and Zika viruses using RT-PCR assays. No viral genes were detected. We discuss the need to continue the monitoring of mosquito occurrences.

    Seventeen individuals blood-fed mosquitoes including 7 species were collected in the Kansai area and the Ryukyu Archipelago, Japan, from 2009 to 2012. The sources of the blood meals were identified by PCR sequencing. The results showed that Aedes bekkui fed on human Homo sapiens, raccoon dog Nyctereutes procyonoides, and wild boar Sus scrofa. Aedes flavopictus miyarai fed on tortoise Cuora flavomarginata evelynae. Verrallina nobukonis fed on human and tortoise. Culex vagans fed on bird, dark-throated thrush Turdus ruficollis; Cx. infantulus fed on cattle; Cx. nigropunctatus fed on bird, night heron Nycticorax nycticorax; and Cx. okinawae fed on otton frog Babina subaspera. Aedes f. miyarai and Cx. infantulus were the first record to feed on cold-blooded animals and warm-blooded animals, respectively.

    We received a special permit to collect dipterous insects, such as mosquitoes, horse flies, and biting midges, in Ozegahara, which is a protected area in Oze National Park and the largest wetland in Honshu, Japan. Herein, we report on the mosquito larvae survey conducted on August 6 and 7, 2023. A total of 28 mosquito larvae and a pupa were collected, comprising 3 species of mosquito, namely Culex rubensis, Aedes esoensis, and Ae. japonicus. This is the first report of Cx. rubensis collected from the Ozegahara wetland.
