Polluted surface waters, not just a problem for aquatic organisms: Biomagnification of flood-borne pesticides in plant-feeding aphids

Surface waters are polluted with a variety of contaminants, including synthetic pesticides. A study by Franziska Fiolka and colleagues from the RTG SystemLink in Landau, recently published in the journal “Chemosphere”, is the first to examine if repeated flood events lead to an increase in pesticide concentration in the riparian zone, including plant-feeding insects. It shows that pesticide concentrations in soil and nettle increase with an increase in flooding frequency, and further, that aphids feeding on contaminated riparian plants are able to take up these pesticides.

Non-Target Casualties: The Overlooked Impact of Neonicotinoids on Grassland Plant Bugs – Investigating Agrochemical Exposure in a Prominent but Overlooked Group of Insects

Modern agro-ecosystems are extensively contaminated with pesticides, but the effects of these chemicals on insect biodiversity are poorly understood. Jan Erik Sedelmeir reports in this blog post about a new study, carried out at the Department of Applied Entomology at the University of Hohenheim under the direction of Georg Petschenka.

Current-use pesticides in vegetation, topsoil and water reveal contaminated landscapes of the Upper Rhine Valley, Germany

Landau, 12.03.2025 – A new study by the RPTU Kaiserslautern-Landau, published in Communications Earth & Environment, shows extensive pesticide contamination in the landscape of the Upper Rhine Region. Pesticides disperse across the entire landscape, contaminating soil, vegetation, and water far beyond agricultural zones. The findings shed new light on the potential environmental impacts of conventional agriculture. According to the researchers, pesticide use must be reduced urgently in order to protect non-target areas around fields, orchards and vineyards.
