Question 67

'Wolbachia method' is sometimes talked about with reference to which one of the following?

AOptions

A) Controlling the viral diseases spread by mosquitoes

B) Converting crop residues into packing material

C) Producing biodegradable plastics

D) Producing biochar from thermo-chemical conversion of biomass

BSolution

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.

CStrategy

For science and technology questions that mention specific terms (like 'Wolbachia method'), try to recall their primary application or the field they belong to. Often, such terms relate to contemporary scientific developments or ongoing research. Connecting the term to its most prominent real-world application is key.
