Abstract

Acute and chronic effects of insecticide-endosulfan on the survival and reproduction performance of Moina macrocopa were determined in a laboratory study. Endosulfan concentrations that cause 50% mortality (LC50) after exposure for 24 and 48 h were 3.34 and 0.16 mg L−1, respectively. Average longevity, initial age of reproduction and intrinsic rate of natural increase were reduced at 0.002 mg L−1. Fecundity was greatly reduced by about 70% at 0.0004 mg L−1 and approximately 97% at 0.002 mg L−1 as compared to control organisms throughout the whole life span of 15 days. If environmental concentration of endosulfan do not exceed 0.0004 mg L−1, application of this insecticide is unlikely to induce detrimental effects on these cladoceran populations in agro-ecosystem.
