Development and Preference Assessment of New Mosquito Attractants for Physical Control of Disease-Vector Mosquitoes

Abstract

This study focused on developing new mosquito attractants and evaluating their efficacy to control disease-vector mosquitoes through field experiments. As vectors of diseases such as malaria, dengue, and Zika, mosquitoes pose significant global health risks that are exacerbated by climate change and insecticide resistance. To address these challenges, eco-friendly alternatives are needed. Three newly formulated attractants (Type 1, Type 2, and Type 3) were tested against the commercial attractants BG-Lure and BG-Mozzibait in field trials in Thailand and South Korea. BG-Lure exhibited the highest overall efficacy, whereas Type 3 demonstrated superior performance in South Korea, achieving the highest daily average capture rate under certain conditions. In Thailand, Type 1 showed attraction rates comparable with those of BG-Mozzibait. These findings highlight the variability in attractant efficacy depending on location and mosquito species, underscoring the importance of tailored solutions for effective mosquito control and sampling for other study purposes. These newly developed attractants present sustainable alternatives to chemical control methods and offer valuable insights for improving public health strategies.
