Pink Bollworm : Damage To Cotton Fields


The Pink Bollworm (PBW) is causing significant damage to cotton fields in northern Rajasthan, Haryana, and Southwestern Punjab, with the infestation being more widespread and serious than before.

  • Farmers have been using Bt cotton seeds, which have lost their effectiveness against the PBW.
  • The situation has led to a drastic reduction in cotton yields, making it financially unviable for many farmers.
  • The pink bollworm (Pectinophora gossypiella) is an insect that is a pest in cotton farming.
  • It is native to Asia but has become an invasive species in most cotton-growing countries around the world.
  • It is considered possibly the most destructive pest on cotton worldwide.

Nobel Prize In Medicine 2023:

The Nobel Prize in Physiology or Medicine for 2023 has been awarded to Katalin Kariko and Drew Weissman for their groundbreaking research on nucleoside base modifications that played a pivotal role in the development of highly effective mRNA vaccines against COVID-19.

  • Kariko and Weissman identified a key problem: dendritic cells in the body perceived lab-grown genetically engineered mRNA as foreign, triggering an inflammatory response.
  • The Breakthrough:
    • To address this issue, they experimented with chemically modifying the bases in mRNA.
    • By introducing unique chemical alterations in the mRNA bases and delivering them to dendritic cells, they reduced the inflammatory response.
    • These groundbreaking results were published in 2005, with further developments in 2008 and 2010.
