The ecdysteroid system is used by crustaceans and other arthropods as the major endocrine signalling molecules, regulating processes such as molting and embryonic development. The aim of this study was to evaluate the ecdysteroid activity of two pesticides (atrazine and endosulfan sulphate), with distinct modes of action and which act in the juvenoid system of the crustacean Daphnia magna as weak juvenoid compounds. To assess the ecdysteroid activity, we first exposed maternal daphnids and… CONTINUE READING
