The effect of the insecticide Tanrec® at concentrations of 3.0 × 10–7, 3.0 ×10–2, and 3.0 × 10–1 mg/L (as of imidacloprid) on Daphnia magna Straus has been studied. An acute toxic effect of this insecticide at a concentration of 3.0 × 10–1 mg/L and a depressive effect at concentrations of 3.0 × 10–2 mg/L and 3.0 × 10–7 have been revealed. A damaging effect of Tanrec was revealed during the stage of early development of studied crustaceans. This effect was manifested in the inhibition of the growth of oocytes, abnormal functioning of the intestine, retardation of body growth, and pathological changes in tissues.
