No Sting, All Gain: Nagaland University researchers discover stingless bees can boost crop yields

• “With the introduction of stingless bees as pollinators in different crops under greenhouse conditions, the yield and quality of produce increased several times in different crops.
• 
  
• “Stingless bees could be used for pollination without fear of being stung. They are known for their popular medicinal honey and pollination potential, which paves the way for the formulation of crop pollination calendars to benefit all stakeholders. The honey produced by the bees during the experiments also provided extra income besides good crop production,” the press release stated.
• 
  
• The research specifically highlighted the positive impact of stingless bee pollination on chilli crops. Compared to crops without pollination, those pollinated by stingless bees showed a marked increase in both production quantity and quality.
• 
  
• “For supplementing the pollination deficit in chilli, stingless bees and honeybee species like A dorsata, A florea - and other wild bees like halictid bees, syrphid bees and Amegiella bees need to be conserved,” it suggested.
• 
  
• In king chilli, the fruit set percentage increased to 29.46% compared to the 21% observed in non-pollinated crops. Similarly, in chilli (Capsicum annuum), fruit set and healthy fruit yield increased by 7.42% and 7.92%, respectively, compared to non-pollinated crops.
• 
  
• Seed weight, a crucial indicator of viability and germination, also saw a remarkable increase of 60.74% when pollinated by stingless bees.
• 
  
• “This is the maiden attempt to work out the pollination potential of stingless bees and quality production of honey, which led to increased income and sustainable livelihood. Earlier, it was difficult to use honeybees for pollination of crops (inadequate pollination) due to their natural attributes,” it added.
