The invention discloses application of an iron-containing substance to preparation of a product for inhibiting dengue virus propagation. The invention firstly discloses the application of the iron-containing substance to preparation of a product for inhibiting dengue virus propagation and/or inhibiting susceptibility of mosquitoes to dengue viruses. The invention further discloses a method for inhibiting dengue virus preparation and/or inhibiting susceptibility of the mosquitoes to the dengue viruses. According to the invention, experiments prove that hosts in different iron states, who are infected by the dengue viruses and bitten by aedes aegypti, have remarkably different virus infection rates, and the susceptibility of the aedes aegypti to the dengue viruses is remarkably negatively correlated with the iron state of the host blood. Further, the susceptibility of the aedes aegypti to the dengue viruses can be effectively reduced by supplementing iron to an iron-deficiency mouse model, which shows that the iron-containing substance can reduce the virus carrying capacity of the aedes aegypti and block propagation of the viruses in nature.

Provided are systems, constructs, genetically modified organisms, and methods for greatly reducing or eliminating local populations of Aedes aegypti mosquitoes, and associated Dengue fever, yellow fever, Zika virus, and Chikungunya virus. Provided are genetically modified Aedes aegypti having a Cas9-mediated split gene-drive system for masculinizing the mosquito and ensuring that any female carries a sterile mutation. In addition, gRNAs direct Cas9 cleavage of insecticide-resistance loci, rendering female mosquitoes escaping the male converting gene drive sensitive to insecticides.
