نبذة مختصرة : The increasingly uncontrolled proliferation of pesticide use today affects the life of all creatures negatively. Pyraclostrobin (Pyra) is a strobilurin class fungicide, which has been widely used in recent years and is known to be toxic to aquatic species. In this study, the effects of Pyra at increased concentrations between 25-1000 µg/L on reproductive performance and genotoxicity of a model organism, Drosophila melanogaster , were investigated. It was found that Pyra decreased reproductive performance and pupa formation from larvae in D. melonagasters in parallel with the dose increase. In addition, it was found that Pyra concentrations (between 200-1000 µg/L) administered to male and female adults caused DNA damage in D. melonagasters , in parallel with their increased concentrations. As a result, it was concluded that Pyra at high concentrations may have a negative effect on D. melanogasters and therefore on the ecosystem of the living creatures.
