‘Wolbachia method’ is sometimes talked about with reference to which one of the following?
- A. (a) Controlling the viral diseases spread by mosquitoes
- B. (b) Converting crop residues into packing material
- C. (c) Producing biodegradable plastics
- D. (d) Producing biochar from thermochemical conversion of biomass
Answer: A
Explanation
The Wolbachia method involves introducing the naturally occurring Wolbachia bacteria into Aedes aegypti mosquitoes, which are vectors for diseases like dengue, Zika, and chikungunya. When present in these mosquitoes, Wolbachia can reduce their ability to transmit viruses to humans. It can also affect mosquito reproduction, leading to a reduction in mosquito populations. This method is a biological control strategy for combating mosquito-borne viral diseases. The other options are unrelated to the Wolbachia method.
