Pesticides and Pollinators: New Research on the Impacts of Farming Activities on Bee Populations

A guest post by Erica K. Brockmeier

The following post is one of a series generated from research presented at the SETAC Europe Annual Meeting in Brussels, Belgium (7-11 May 2017). Each post features the latest research findings from SETAC scientists on emerging topics of interest.

Are pesticides hurting pollinators?

The widespread loss of honeybee populations in Europe and the reduced numbers of wild bees in other countries sparked concern among scientists, policymakers, and farmers all across the world. Recent research conducted on historical field data found a potential connection between the use of certain insecticides and changes in wild bee populations. This was especially true for species that are known to visit flowering crops like oil seed rape.

US Federal Government Taking Aim at Protecting Pollinators

A guest post by Richard J Wenning, Editor-in-Chief, Integrated Environmental Assessment and Management (IEAM).

Next week is National Pollinator Week in the US (June 15-21, 2015), and a good time to consider the importance of bees, birds, butterflies, and bats for a healthy ecosystem. Pollinators contribute more than $24 billion annually to the US economy by tending to the vineyards, orchards, farmlands, nurseries, and countless acres of open space used by tourists every year. Pollinating requires a significant natural work force. But right now, nature’s workers are not doing so well. Continue reading

Neonicotinoid Pesticides: New Findings Highlight Their Role in the Disappearance of Bees

Bees have been declining for years worldwide—this is a well-accepted fact. However, the “why” of this decline is still a matter of debate. Although it is likely that a combination of different factors is contributing to the global bee die-offs, increasing attention is now devoted to the toxic effects of a group of pesticides called neonicotinoids, or neonics for short. They are systemic pesticides—their solubility in water allows them to reach leaves, flowers, roots and stems, even pollen and nectar. One could therefore infer that these pesticides will likely kill not only the insects that farmers want to eliminate, but also pollinators. Continue reading
