Abstract: With the development of molecular biology, non-coding sRNA has been found to play an important regulatory role in gene expression and protein activity, affecting various biological pathways including mosquito resistance against insecticides. Understanding the molecular regulatory mechanisms of drug resistance is essential for controlling mosquitoes, , of which metabolic resistance being the most critical mechanism, mainly referring to the high expression of metabolic detoxification enzyme-related genes (especially the cytochrome P450 enzyme system) in mosquitoes. On the basis of verification of insecticide resistance-related genes, further research on the correlation between sRNA and mosquito resistance-related genes provides new ideas and directions for further exploring the mechanism of mosquito resistance. The study of mosquito metabolic resistance mechanism is of great significance for the control of vector mosquitoes, drug resistance monitoring and novel insecticide development. This article reviews the progress of research on the resistance genes, sRNAs biosynthesis, genes involved in regulating mosquito metabolic detoxification enzymes and their applications.
