GM Mosquitoes

  • Trial launched in Dawalwadi, Badnapur, Jalna district, Maharashtra
  • Suppress wild female mosquito populations that transmit dengue, chikungunya and Zika
  • Done by Oxitec and uses the Release of Insects carrying Dominant Lethal genes (RIDL) technology
  • Oxitec’s technology uses GM male Aedes aegypti mosquitoes that carry a dominant lethal gene - > passed to offspring - > lethal gene in the offspring kills the larvae before they reach adulthood.
  • Oxitec’s mosquitoes were first released in Brazil were they have successfully reduced the local populations of mosquitoes by more than 90%, whereas insecticides only affect 30%.

Wolbachia

  • It is Bacteria present in many insects and few mosquitoes excluding Dengue mosquitoes, Malaria Mosquitoes etc.
  • Transmitted genetically
  • Not harmful to Human beings. Wolbachia method of eradicating dengue and Malaria is being used by Researchers. When introduced in Dengue and Malaria mosquitoes they lose the ability to spread infection to humans.

Colony Collapse Disorder

  • Worker bees from a European honey bee colony abruptly disappear.
  • Called as disappearing disease, spring dwindle, May disease, autumn collapse, and fall dwindle disease
  • Called colony collapse disorder in 2006 with drastic rise in the number of disappearances of western honeybee colonies in North America.
  • Occurred also in Belgium, France, the Netherlands, Greece, Italy, Portugal, and Spain, Switzerland and Germany.
  • Agricultural crops worldwide are pollinated by European honey bees around $200 billion in 2005.
