Vaccine For Honey

Context: United States Department of Agriculture (USDA) has granted a conditional license for a vaccine for honeybees (World’s first vaccine) to curb American foulbrood (AFB).

  • It is a fatal bacterial disease for the insect, caused by the spore-forming bacterium Paenibacillus larvae.
  • The disease can infect the strongest to the weakest colony in an apiary. Heavy infections can affect most of the brood, severely weakening the colony and eventually killing it.
  • The vaccine has been developed by biotechnology company Dalan Animal Health, giving hope of a new weapon against diseases that routinely ravage colonies relied upon for food pollination.
  • The vaccine exposes queen bees to inactive (ie, “dead”) bacteria, which enables the larvae hatched in the hive to resist infection.
  • The vaccine is mixed in queen candy, the primary food source for both the queen bees and the attendant bees living in cages.
  • Eventually, developing bee larvae have immunity when they hatch, which reduces the chances of fatality from the illness.
  • Significance
    • Arrest Declining Honeybee population: Honeybees are declining sharply, spurred by habitat loss, pesticide use and the climate crisis.
    • According to the United Nations Food and Agricultural Organization, about one-third of the world’s crop production depends on pollinators such as bees, birds and bats.
    • The lifespan of the adult honeybee has been reduced by nearly 50 per cent in the past 50 years.
    • A declining population also means less honey.
