Abstract Potential toxic effects of thiamethoxam on nontarget organisms and the community structure a generic Midwestern farm pond emergent wetland were assessed using 2 versions comprehensive aquatic system model: CASM GFP , model, GWL model. The are integrated bioenergetics‐based habitat quality models that describe daily biomass values selected producer consumer populations representative generalized ponds wetlands. demonstrated ability to reproduce population reported for (and other) ecosystems; provided similar modeling capability Lethal sublethal modeled as extrapolations laboratory toxicity assays . Time series environmental concentrations constructed 6 regional pesticide applications across United States failed produce any calculated impacts or changes in trophic guilds However, evaluation systematically increased both simulate direct indirect this pesticide. present model study suggests process‐based food web/ecosystem can be used characterize potential ecological ecosystems.
