||The study was designed to determine the effect of using two different ages of mallard (Anas platyrhynchos) adults within the first breeding season on reproductive tests under standard Toxic Substances Control Act avian reproductive guidelines. The adult age groups were 7 and 11 months at test initiation. The test chemical was an organophosphate insecticide, chlorpyrifos. The parameters evaluated included food consumption, adult body weight, brain acetylcholinesterase levels, egg production, fertility, hatchability, egg shell thickness, egg weight, and duckling survival and weight.
