  • Scientists in Colombia say they have developed a new food substance that protects bees from dangerous chemicals used in farming.
  • 2
  • They claim it will protect the insects' brains from neurological damage caused by chemicals called pesticides.
  • 3
  • As pollinators, bees are extremely important in the preservation of natural ecosystems and food production.
  • 4
  • The plant-based food substance enables bees to deal with neurotoxins commonly used in agriculture.
  • 5
  • It protects their motor system and memory harmed by the chemicals.
  • 6
  • Researchers at Colombia's Rosario University in Bogota developed the substance.
  • 7
  • They partnered with scientists from the Colombian Universidad Javeriana and the University of Arizona in the United States.
  • 8
  • "This is a nutritional solution to the problem bees face when exposed to pesticides," said Andre Riveros, a professor at Rosario University.
  • 9
  • Riveros explained that the food substance causes the bees to develop protection against pesticides.
  • 10
  • The substance is created with flavonoids, which are known for their health benefits.
  • 11
  • Flavonoids come from plants and are a kind of secondary metabolite. Secondary metabolites are substances made by plants that make them competitive in their environment.
  • 12
  • During the first round of testing, scientists put the bees to sleep and placed them into small laboratory tubes.
  • 13
  • Then, they fed the bees the substance one by one.
  • 14
  • Testing has now moved to real-world situations in a bee colony at the university, said Juan Jose Ovalle.
  • 15
  • He is a natural science student at Rosario University.
  • 16
  • "We already know that there are molecules that improve the bees' health. We already know that there are molecules that prevent neuronal damage caused by pesticides," Ovalle said.
  • 17
  • He added it was important to continue the work to increase the effectiveness of these methods to support bees.
