TOXIC EFFECT OF IMIDACLOPRID ON THE DEVELOPMENT OF DAPHNIA MAGNA LINEAGE
Neonicotinoids (which include imidacloprid) are the world’s most widely used insecticides, with global production valued at US$ 2.5 billion and registrations in more than 120 countries. Imidacloprid insecticide was detected in the water samples at the sites of constant ecological and toxicological monitoring. The toxic effect of imidacloprid concentrations of 3,0 х10-7 and 3,0 х10-2mg/l on successive generations of Daphnia magna was studied. The effects on fertility indicators, linear sizes of daphnia were determined. The influence of toxicant both on parents and the succeeding generations were observed. The adaptation of Daphnia magnato imidacloprid could not be found in four successive generations.
