The Toxic Effects Of Malathion (Organophosphate Insecticide) On The Daphnia Magna Straus, 1820 (Crustacea, Cladocera), Maryam Rassoulzadegan, Nusret Akyurtlakli

Turkish Journal of Zoology

The toxic effects of technical grade (95 %) malathion and commercial (25 %) malathion were investigated on young (£ 24 h old) Daphnia magna in static acute toxicity tests (24 and 48 h). The culture of D. magna and toxicity tests were performed at 24 ± 1 ºC with a photoperiod of 16 h light and 8 h dark. To obtain a healthy population, the fecundity of each female in their life cycle was also investigated. The immobilization of daphnids was considered for determination of the 24 h / 48 h effective concentration (50 %). The EC50 values were found …
