Explanation

The 'Wolbachia method' is an innovative biological control strategy used to combat vector-borne diseases, particularly those transmitted by mosquitoes. *Wolbachia* are naturally occurring bacteria that infect a wide range of insect species. When *Wolbachia*-carrying mosquitoes are released into an area, they can breed with wild mosquitoes, passing the bacteria to their offspring. The presence of *Wolbachia* in mosquitoes can either prevent viruses (like Dengue, Zika, Chikungunya, and Yellow Fever) from replicating effectively within the mosquito or reduce the mosquito's lifespan, thereby reducing the transmission of these viral diseases to humans.
