Wolbachia UPSC NOTE


  • Wolbachia is a genus of bacteria that has evolved complex relationships with the many insects that can host it. 

  • It is named for the American pathologist Simeon Burt Wolbach, who identified it along with Marshall Hertig in 1924.

  • In 1971, researchers discovered that when male Culex mosquitoes infected by Wolbachia bacteria fertilised healthy eggs from a female, the eggs died

  • The bacteria modified the male’s sperm cells in a way that only the bacteria could reverse

  • Infected female mosquitoes gain a reproductive advantage over time as the amount of Wolbachia in the population increases.

  • Wolbachia can also reduce the rate at which chikungunya and yellow fever viruses multiply in infected mosquitoes. 

  • Scientists have also found that some Wolbachia species can strongly protect some mosquito species against the malaria parasite

  • In the right environmental conditions, such that the bacteria can suppress malaria transmission. 

  • If this is achieved, it will be a significant weapon in our millennia-long fight against mosquito-borne diseases.
