Preferred citation for this article: Wu Z.Q., 2024, Using Bacillus thuringiensis var. israelensis to control mosquito larvae in aquaculture (Aedes spp.): an ecological control strategy, Journal of Mosquito Research, 14(2): 67-75 (doi: 10.5376/jmr.2024.14.0008) Abstract As the threat of mosquito-transmitted diseases to public health continues to intensify, the search for environmentally friendly methods of mosquito control has become a hot topic of research. Bacillus thuringiensis var. israelensis (Bti), an efficient biocontrol agent, has garnered widespread attention for its role in controlling mosquito larvae in aquaculture environments. This study provides a comprehensive overview of Bti's application strategies, ecological and environmental impacts, challenges, and management approaches, aiming to evaluate its potential as a sustainable strategy for mosquito larva control in aquaculture. The study analysis reveals that Bti exhibits excellent performance in controlling specific mosquito species, yet it also raises concerns such as potential impacts on non-target organisms, the development of resistance, and application costs. There is a need to further enhance the efficiency of Bti's application, explore strategies to mitigate resistance development, and conduct long-term environmental impact assessments. Furthermore, given that a single control method often falls short in addressing complex ecological issues, a comprehensive mosquito management strategy is particularly crucial. Through this in-depth analysis, we aim to provide robust theoretical support for ecological mosquito control in aquaculture and offer new ideas and directions for public health protection efforts. Keywords Bacillus thuringiensis var. israelensis (Bti); Mosquito Larvae; Public Health; Aquaculture; Ecological Control Globally, mosquitoes pose a serious threat to human health as vectors of many diseases. These diseases include, but are not limited to, dengue fever, yellow fever, and Zika virus disease, which cause a large disease burden globally, especially in tropical and subtropical regions (Iosr et al., 2015). In addition to direct threats to human health, the widespread presence of mosquitoes in aquaculture environments may also have negative impacts on the aquaculture industry, including disrupting ecological balance and reducing water quality, thereby affecting breeding efficiency and production (Rudd et al., 2023). Given the environmental pollution and ecological risks that chemical control methods may bring, it is particularly important to find environmentally friendly mosquito control strategies. Bacillus thuringiensis var. israelensis (Bti) is a biological pesticide widely used to control mosquito larvae. Due to its high efficiency, specificity and environmental friendliness, it has become one of the preferred methods for controlling mosquito larvae. The use of Bti can not only effectively reduce mosquito populations and reduce the risk of disease transmission, but also has less impact on non-target organisms and the overall ecosystem, providing the possibility of achieving sustainable mosquito management (Mo-on et al., 2022). The purpose of this study was to comprehensively evaluate the effectiveness and impact of Bacillus thuringiensis var. israelensis in controlling (Aedes spp.) mosquito larvae in aquaculture environments, and to explore its practical significance and potential value as an ecological control strategy. By analyzing Bti's application strategies, ecological and environmental impacts, as well as challenges and management strategies, this article aims to provide a new mosquito control strategy for the aquaculture industry that reduces the use of chemical pesticides and protects the ecological environment, and also provides public Health protection provides support to reduce the health burden caused by mosquito-borne diseases.
