In simulated present‐day scenarios, a NOAEC/2 of pyrimethanil as derived from a life‐cycle toxicity test provoked only slight‐to‐moderate beneficial or adverse effects on <jats:italic>C. riparius</jats:italic>. In contrast, exposure to a NOAEC/2 concentration of pyrimethanil at a thermal situation likely for a summer under GCC conditions uncovered adverse effects on mortality and population growth rate. In addition, genetic diversity was considerably reduced by pyrimethanil in the future scenario, but only slightly under current climatic conditions. Our multigeneration study under near‐natural (climatic) conditions indicates that not only the impact of climate change, but also low concentrations of pesticides may pose a reasonable risk for aquatic insects in future.</jats:p> Simulated climate change conditions unveil the toxic potential of the fungicide pyrimethanil on the midge <i>Chironomus riparius</i>: a multigeneration experiment Ecology and Evolution |
