Implementation of CRISPR/Cas9 methodologies for mosquito gene editing has not yet become widespread. This protocol details the procedure for Aedes aegypti mosquito gene editing using homology-directed repair and fluorescent marker insertion, which facilitates the generation and screening of mutant mosquito lines for gene function testing. We describe optimized methods for single guide RNA plasmid preparation, homologous recombination donor plasmid construction, embryo microinjection, and precise gene knock-in confirmation. We also provide general guidance for establishing mutant mosquito lines. For details on the practical use and execution of this protocol, please refer to Li et al. (2020).
