The effect of two pesticides, the diflubenzuron (DFB) and flucycloxuron (FCX) was studied on the ciliated protiste cellular model, Paramecium sp. Treatment with the DFB at 10 and 20 µg/ml reduces the growth of this protiste appreciably. The survey of the respiratory metabolism by the polarography technique (oxygen electrode) shows a sensitive inhibition of the oxygen consumption. In the case of the FCX, treatment with the two concentrations (10 and 20 µg/ml) reveals an inhibition of the ciliated protiste growth. This pesticide also inhibits the respiratory metabolism of ciliated protiste. This effect is a lot more marked with the FCX that with the DFB.
Key words: Paramecium sp., flucycloxuron, diflubenzuron, pesticide, respiratory metabolism.
