Assessing the fate and effects of an insecticidal formulation
A three‐year study was conducted on a corn field in Central Illinois, USA, to understand the fate and effects of an insecticidal formulation containing the active ingredients phostebupirim and cyfluthrin. The objectives of the current study were to 1) determine the best tillage practice (conventional versus conservation tillage) in terms of grain yields and potential environmental risk, 2) ...

Living on the edge: Populations of two zooplankton species living closer to agricultural fields are more resistant to a common insecticide
Ecological communities across the globe are exposed to a diversity of natural and anthropogenic stressors and disturbances that can lead to community‐wide impacts. Contaminants are a group of anthropogenic disturbances that are ubiquitous in the environment and can trigger trophic cascades, increased susceptibility to pathogens, reduced biodiversity, and altered ecosystems. In these ...

The effects of the amphibian chytrid fungus exposure to American toads in the presence of an insecticide
Abiotic factors like pesticides may alter the impact of a pathogen on hosts, which could have implications for host‐pathogen interactions and may explain variation in disease outbreaks in nature. In this laboratory experiment, we exposed American toad (Anaxyrus americanus) metamorphs to the amphibian chytrid fungal pathogen, Batrachochytrium dendrobatidis (Bd), and environmentally relevant ...

Is the chronic Tier‐1 effect assessment approach for insecticides protective for aquatic ecosystems?
We investigated the appropriateness of several methods, including those recommended in the Aquatic Guidance Document of the European Food Safety Authority (EFSA), for the derivation of chronic Tier‐1 Regulatory Acceptable Concentrations (RACs) for insecticides and aquatic organisms. The insecticides represented different chemical classes (organophosphates, pyrethroids, benzoylureas, insect ...
