There is growing concern over the impact of the neonicotinoids to insect pollinators and how their loss may limit the ecosystem services that are vital to our food production (globally worth US$215 billion) and the stability of our natural environment.
In a new study, published in Scientific Reports, researchers directly relate the effects of three neonicotinoids, at the level of individual brain cells to their impact on whole colonies of bumblebees placed at 5 different sites across Scotland. The conclusions from this study demonstrate that these three neonicotinoids must be considered individually for their risk to bees. Most importantly, the research asks whether they are all toxic (when exposed chronically to field-relevant levels) to bumblebees under the conditions of a field experiment.
