New research paints a worrying picture for the different species of bees that provide multi-million-euro pollination services in Ireland each yea. The work raises concerns about the potential wide-spread exposure to multiple chemicals from two pesticide categories (fungicides and neonicotinoid insecticides) and indicates that different bee species may be exposed differently to pesticides -- meaning that assessments of pesticide risk to honey bees may not be easily extrapolated to other bees.
New research paints a worrying picture for the different species of bees that provide multi-million-euro pollination services in Ireland each year. The work raises concerns about the potential wide-spread exposure to multiple chemicals from two pesticide categories and indicates that different bee species may be exposed differently to pesticides -- meaning that assessments of pesticide risk to honey bees may not be easily extrapolated to other bees.
Crop pollen was only contaminated with fungicides; honey bee pollen was mostly contaminated with fungicides; bumble bee pollen mostly by neonicotinoid insecticidesAll five neonicotinoid insecticides assessed were found in bumble bee pollen -- even though these had not been applied recently to the sampled fields
"The results of this study are concerning on several levels. Of particularly great significance is the indication that different species seem to be exposed to pesticides differently based on the variation in the types and number of different pesticides found in pollen of honey and bumble bees respectively.
