To fight agents malaria scientists naturally modify Anopheles Gambia mosquito species [ Current Affairs ]


To fight the deadly disease of malaria scientists have naturally modified malaria-causing mosquito Anopheles Gambia species to fight. The research was successfully conducted by team of researchers under the leading of London based Imperial College.

It was published in the journal Nature Biotechnology.

Key facts:

  • Regarding this DNA segment disrupting egg production in female mosquitoes has been naturally modified Anopheles Gambia mosquito species by Scientists.
  • For this gene drive technology had been used a by them which includes the technique of recessive genes and so that many mosquitoes will inherit only one copy of the gene.
  • For fertility two copies in female Anopheles Gambia mosquitoes are needed generally.
  • On the other hand one copy of the gene makes female infertile by disrupting egg production.
  • CRISPR/Cas9 endonuclease was used for modification of genes and it was type of DNA cutting tool that modify the very specific parts of the genetic code.
  • To significantly reduce the malaria-carrying mosquito species attribute of modified gene can be passed through a population of mosquitoes over time.
  • It will help to increase ability to develop novel methods of vector control by these judgments which will be important step in scientific world.
  • It should be noted that In African state 90 % of annual deaths occur due to mosquito species Anopheles Gambia which carries most dangerous malaria parasites in sub-Saharan.
  • According to the survey every year more than 430, 000 people causes deaths due to malaria across the world.
