Weed killer might be hurting honey bee populations around the world, according to a new study.
Glyphosate is leaving honey bees more susceptible to infection and death, University of Texas at Austin researchers say in a study published Monday in the journal Proceedings of the National Academy of Sciences.
Glyphosate, a herbicide, is the controversial active ingredient in popular weed killers such as Roundup.
Bees that came in contact with the herbicide glyphosate in the study had lower levels of healthy gut bacteria that helps digest food and ward off sickness and were more likely to die from pathogens. About half of the healthy bees survived the introduced pathogen Serratia marcescens. Only a tenth of bees affected by glyphosate survived.
We need better guidelines for glyphosate use, especially regarding bee exposure, because right now the guidelines assume bees are not harmed by the herbicide, Erick Motta, a graduate student who led the research, said in a statement. Our study shows thats not true.
