Researchers created a non-invasive tool to sample environmental contaminates in honeybee hives.
Bees are good bioindicators of environmental contamination because they get coated with everything in their surroundings, including pollutants. Because they have a wide flight range and sample from a range of spaces, they can pick up build-up from the air, water, ground and trees. They also spread the nectar they collect to other bees and throughout the hive.
Researchers have used honeybee hives to understand the environmental contamination in their area in the past, but the process was often harmful. It involved capturing bees and extracting whatever they had ingested or transported on the surface of their bodies. Sampling could also be done with pollen reserves, larvae and honey. Not only was this often very difficult and time-consuming, it also often disrupted the normal functioning of hives, according to a PHYS.ORG article.
Professor José Manuel Flores, from the Department of Zoology at the University of Cordoba, collaborated with researchers at the University of Almeria to put a new device into operation. APIStrip (Absorb Pesticide In-Hive Strip) is a non-invasive polystyrene strip that is placed in a hive and can absorb a variety of pesticides and other pollutants for testing. This device will allow researchers to continue to use honeybees as sample collectors and improve environmental health without jeopardizing the safety of honeybee colonies.
