<abstract xmlns="http://www.w3.org/1999/xhtml"> Modelling the influence of different concentrations of lead and cadmium ions upon a laboratory culture of insects has not been adequately studied. In our research, we assessed the influence of cadmium and lead nitrates at different concentrations (10-2-10-9 М) upon the development of larvae, pupae and imagines of Calliphora vicina Robineau-Desvoidy, 1830 (Diptera: Calliphoridae). We found an acceleration in the development of larvae and an increase in mass of puparia when lead ions were added to the food of the larvae, and decrease in the mass of puparia when cadmium ions were added. We registered nanism and malformation of the fly imagines in experiments with lead and cadmium in the food substrate. We observed that under the influence of the studied heavy metal ions there was a reduced motor activity of the fly larvae at all stages of development, a delay in formation of puparia and a delay in the emergence of imagines in comparison with the control group.</abstract>
