“…Albopictus. The method used to irradiate larval to pupal stages was the same as that in our previous study 6 . Hatchlings were collected from the stock cultures within 12 h of hatching and were placed (n = 10) in water (50 mL) in polyethylene terephthalate (PET) ice-cream cups (60 mm diameter × 38 mm height, Risupack, Co., Ltd., Aichi, Japan).…”

“…It has been revealed that ~ 440-and ~ 470-nm blue lights show higher toxicity to D. melanogaster than that at ~ 380-nm UVA 1 . Moreover in C. pipiens f. molestus, the toxicity of ~ 420 nm blue light is shown to be higher than that of ~ 380 nm UVA 6 . Therefore, in this study, we also investigated the toxicity of ~ 380-nm UVA to Ae.…”

“…However, the use of larvicides has certain disadvantages, such as the development of insecticide resistance and disruption of the aquatic ecosystem. Therefore, eco-friendly control techniques that can kill immature stages of mosquitoes need to be developed.In mosquitoes, we have previously demonstrated the lethal effect of blue light on Culex pipiens form molestus 1,6 . The mosquito vectors mainly belong to three genera, Aedes, Anopheles, and Culex 7 .…”

In our previous studies, we found that blue light has a lethal effect on various insect species and demonstrated that the most effective wavelength to control the hygiene pest, the mosquito, Culex pipiens form molestus (Diptera: Culicidae), is ~ 420 nm through all developmental stages. The genera Aedes and Culex include many globally crucial hygiene pest species that transmit serious diseases to humans and animals. However, effective lethal wavelengths have been shown to differ among insect species. In this study, we investigated the lethal effects of blue light on the Asian tiger mosquito, Aedes albopictus, using light-emitting diodes. Blue-light irradiation had a lethal effect on the larvae, pupae, and adults of Ae. albopictus. In particular, the 417-nm blue-light wavelength had a strong lethal effect on the larvae, showing 100% mortality before pupation at the photon flux density of 10 × 1018 photons·m−2·s−1. In contrast, no blue-light wavelength had a lethal effect on the eggs. Moreover, the 417-nm wavelength had the strongest effect on the pupae among the tested blue-light wavelengths. Our findings indicate that ~ 420 nm is the most promising blue-light wavelength to control populations of Ae. albopictus and C. pipiens f. molestus.
