Chlorothalonil, a widely used fungicide in agriculture, has raised concerns regarding its impact on non-target species. This study examined the effects of chronic chlorothalonil exposure larval development and reproductive performance vinegar fly, Drosophila melanogaster. eggs were reared diet supplemented with sublethal concentrations (5-120 mg kg-1). Larval pupation was measured as an indicator survival growth, while fecundity, ovariole count body weight served proxies for female performance. A ferrozine assay to examine mitochondrial mitoferrin activity males marker related iron metabolism. Chlorothalonil decreases survival, extends developmental duration reduces fecundity. Even at lowest tested concentration, resulted reduced weight, egg production compared non-exposed individuals. Male flies also demonstrated levels. These findings underscore that chronic, not only induces mortality but adversely affects fecundity adult insects. Assessing toxicological agrochemicals organisms is critical understanding broader environmental impacts these substances. Such insights are vital developing conservation strategies safeguard ecosystems support biodiversity promoting sustainable agricultural practices.
