TOXICOLOGICAL STUDIES ON THE CRUSTACEAN ANIMAL DAPHNIA - USING SOME lNSECTIClDES

Abstract
In studying the acute toxicity of 14 different insecticid s against
the freshwater cladoceran fleas, Ceriodaphnia quadrangula and
Daphnia magna, the insecticide Cyfluthrin showed the heighest toxicity,
while Dimethoate exhibited the least effect.
The joint action analyses for 45 different insecticidal pairs indicated that most of their mixtures possess potentiation effects.
Sub-lethal concentrations of different insecticides tested were
found to induce variable effects on daphnids heart beat rate. This has
enabled us to propose a method for distinguishing between organo
phosphorus, carbamate and synthetic pyrethroid insecticides hen be
present in water, as contaminants, at very low concentrations. ·
In conclusion, the data obtained highlight the importance of
daphnid crustaceans as bioindicators in aquatic toxicological studies
