Gene-Drive Technology: UPSC NOTE

 Mosquito-Borne Diseases

  • Mosquitoes have been a constant presence throughout human history, causing annoyance through bites and transmitting deadly diseases.

  • Earliest known mosquitoes from fossils date back at least 70 million years, with evidence of mosquito-borne diseases like malaria traced back to Egyptian mummies from 2000 BC.

  • Mosquitoes are vectors for various diseases including malaria, dengue, Zika, lymphatic filariasis, and yellow fever.

Gene-Drive Technology:

  • Gene-drive technology is a genetic engineering approach used to control the inheritance of specific genes within populations of organisms. 

  • It is designed to rapidly spread or modify particular genes throughout a population, often with the goal of reducing the population size or altering its characteristics

  • Gene-drive technology is a major approach in genetic manipulation, altering mosquito populations' inheritance of genes to reduce reproduction or sterilize them, ultimately disrupting disease transmission.

Benefits and Risks:

  • These technologies offer benefits but also pose risks, including potential ecological disruptions and unintended consequences.

  • The reduction in mosquito populations may affect food chains and ecosystems, leading to uncertainties in short and long-term implications.

Challenges and Regulations:

  • Genetic engineering of mosquitoes and genetically modified mosquito trials face challenges worldwide, with concerns about ecological impacts and gene spread.

  • Regulations and guidelines, such as those released by the Department of Biotechnology in India, aim to address these concerns and provide a framework for research and implementation.
