Action of detergent products in the aquatic larvae of Chaoborus and Cloen: importance of their physiological activity (author's transl)

For the Chaoborus larvae (Diptera), the toxic effect of detergents depend on their physiological activity: the diapausing animals are less sensitive. On other respects, the speed of this effect is linked to the chemical composition of the detergents. For the Cloeon larvae (Ephemeroptera) these products seem to interfere with the molting process: some of them induce a decrease in the molting frequency, others are without effect; on the other hand a commercial washing powder induces a real increase of this frequency.
