Abstract The Asian mosquitoes, Aedes albopictus (Skuse) and Aedes japonicus japonicus (Theobald), have invaded North America, Europe, and other regions since the late 20th century. In invasive ranges, Ae. albopictus has well been recognized as urban, domestic species, whereas views about the macrohabitats of Ae. j. japonicus are inconsistent. Previous reports in Japan suggest the disappearance of Ae. j. japonicus from metropolises. However, container-mosquito larvae have not been inspected simultaneously for various macro and microhabitats in metropolises in Japan. The current study in Fukuoka City, a metropolis in southwest Japan, confirmed the absence of Ae. j. japonicus irrespective of macrohabitats (temples with graveyards, shrines, public graveyards, cultivated bamboo groves, and urban forests, all within the area densely inhabited by humans) and microhabitats (container types). In contrast, Ae. albopictus was dominant throughout the macro and microhabitats except forest tree holes rich with competitive species. Past records indicate the disappearance of Ae. j. japonicus from metropolitan Fukuoka within the last 70 yr. Based on careful examination of available evidence, we concluded that 1) both species benefit from human-made environments with artificial containers free from competitors, 2) Ae. j. japonicus disappeared due to hot, dry summer conditions facilitated by urban heat-island effects and a decrease in favored mammal hosts, and 3) Ae. albopictus has proliferated with higher tolerance to hot, dry climate and a wider blood-feeding host-range including humans. This difference is important for efficient control of each species as well as predicting and preventing the expansion into new distribution ranges.

The Impact

Abstract Aedes albopictus, the Tiger Mosquito, has been hailed as one of the most invasive arbovirus-transmitting mosquitoes globally. With the growing potential of microbial methods for mosquito control, it has become increasingly imperative to understand the factors that contribute to naturally-occurring microbiome communities. Here, we analyzed the impact of larval water type and life stage on the microbial community of Aedes albopictus. The field-collected water samples from tree holes and tires that were used to rear larval mosquitoes in the laboratory were significantly different from each other in terms of sOTU (bacterial species) richness, with tree holes having a far greater number of sOTUs. For beta diversity measures (Bray-Curtis dissimilarity) Aedes albopictus were not significantly different from adult Aedes aegypti, but mosquito sex, life stage, and overall treatment group were significantly different when analyzed by ANOSIM. Based on our findings, the environment surrounding larval mosquitoes (and subsequent adult mosquitoes from those habitats) and the life stage of mosquitoes (regardless of species) shapes mosquito microbiome assemblages. This work further supports the idea that mosquito adults maintain a microbiome specific to larval habitat, despite major reductions to their microbiome prior to eclosion, which could shape the success of implemented microbial engineering or control methods.
