Abstract
The acute and chronic effects of the organophosphate insecticide malathion on the cladoceran Moina macrocopa were studied. The 24, 48 and 72 h LC50 values for malathion were between 5.00 and 10.00 g L–1. Survival, longevity and the number of young produced by the population were affected by exposure to 0.01 g L–1 or higher concentrations. Exposure to malathion had no effect on the age of first reproduction.
