Abstract:
This work study the risks related to the intensive use of pesticides and particularly
insecticides in agriculture to human health and the environment, several evaluation methods put
in place. These methods go through tests to evaluate the toxicity of these products, especially on
invertebrates, and more particularly on the genus Daphnia. The results obtained during tests on
Daphnia magna; reveals the effect of Lannate 25 WP and Decoys PROTECH insecticides on the
life cycle traits of this bioindicator.Individuals treated with low concentrations (0.1% and 1%) of
the first insecticide are able to complete the acute and chronic test without affecting. However,
high concentrations of the same insecticide and all tested concentrations of the second insecticide
completely immobilize the specimens from the first minutes of contact.
