Answer: (a) Controlling the viral diseases spread by mosquitoes.
Explanation:
The "Wolbachia method" is a biological control strategy used to reduce the transmission of viral diseases such as dengue, Zika, and chikungunya, which are spread by mosquitoes. Wolbachia is a naturally occurring bacteria that infects many insects, including mosquitoes. When mosquitoes are infected with specific strains of Wolbachia, they become less capable of transmitting certain viruses to humans. This method involves releasing male mosquitoes infected with Wolbachia into the wild, which then mate with female mosquitoes, resulting in the production of eggs that do not hatch or produce viable offspring. Over time, this approach aims to reduce the population of virus-transmitting mosquitoes and control the spread of viral diseases.
