Bloodmeal identification and feeding habits of mosquitoes (Diptera: Culicidae) collected at five islands in the Ryukyu Archipelago, Japan

Mosquitoes exhibit distinct host preferences based on genus and subgenus, with some species showing strong mammalophilic tendencies while others, such as Ae. (Geoskusea) baisasi, predominantly feed on fish. A six-year study across five Ryukyu Archipelago islands identified bloodmeals from 975 mosquitoes representing 35 species, revealing that genera like Anopheles and Culex display varied feeding patterns tied to warm-blooded or cold-blooded hosts. Subgenera within Culex also demonstrated divergent preferences, with some favoring mammals and birds while others targeted a broader range of vertebrates. The research used PCR-based bloodmeal identification to analyze mosquitoes collected via five methods from diverse habitats, including forests, residential areas, and animal sheds. These findings highlight the ecological diversity of mosquito feeding habits and their potential implications for disease transmission in UNESCO-listed island ecosystems.
