Colombians seek to protect bees in urban jungle

BOGOTA (AFP-Jiji) — Far from the flowery fields that are their natural home, honey bees imperiled by pesticides in rural Colombia are finding sanctuary on university campuses in the bustling capital Bogota.
Even though hives are banned from the city due to the risk the insects’ stings can pose to humans, universities enjoy an exemption for research purposes.
At the University of Rosario, biologist Andre Riveros very carefully feeds a bee some sugar water, watching attentively as it stretches its straw-like tongue, or proboscis, toward the sweet liquid.
The university boasts a rooftop apiary in a bamboo structure some 6 meters high, surrounded by trees and flowers.
Here, Riveros and his team study a colony of bees in the hopes of developing a food supplement that will offer the critical crop pollinators protection from insecticides
“Pesticides end up affecting some [neurological] regions that, for example, affect learning and memory and [the bees] end up with damage very similar to Alzheimer’s,” Riveros told AFP.
“We are trying to find a solution for the problem of bee disappearances,” he said. “We seek to shield the bees, in essence.”
The team’s work focuses on the Apis mellifera, or Western Honey Bee, one of about 20,000 known species worldwide.
Hundreds of hives have been killed off in Colombia in recent years, and investigations into the cause have pointed to fipronil, an insecticide banned in Europe and restricted in the United States and China.
Fipronil has been widely used in a profitable avocado and citrus boom in Colombia, though the Latin American country suspended its use in some crops for 6 months last year.
‘Fleeing the fields’
Elsewhere in Bogota, the EAN University boasts its own hives, perched on a six-story building overlooking the city of eight million people.
Beekeeper Gino Cala extracts honey from the hives as part of his work to instruct and assist universities in the management of urban apiaries.
But Cala said Colombia’s bees “are fleeing the fields” partly due to the “indiscriminate use of agrochemicals.”
“These insects are extremely relevant and important … because they help guarantee part of the food security of Colombia and the world,” he added.
From the EAN University grounds, Cala’s bees help to pollinate plants in surrounding areas.
About 1.4 billion jobs and three-quarters of all crops around the world, according to a 2016 study, depend on pollinators — mainly bees — which provide free fertilization services worth billions of dollars.
In recent years, bees in North America, Europe, Russia, South America and elsewhere have started dying off from “colony collapse disorder,” a mysterious scourge blamed partly on pesticides but also on mites, viruses and fungi.
The U.N. warns that nearly half of insect pollinators, particularly bees and butterflies, risk global extinction.
Despite the city ban, there are private beekeepers in Bogota who sell products such as honey, pollen or beeswax.
A fire department in Bogota said it attends to eight bee sting-related emergencies on average every day.
