Vliv potravy kontaminované manganem na vývoj fytofágů
 Šťasta, Michal
Foreign substances (including heavy metals) enter to the food chain of the animal part of ecosystem can affect the development of organism, its mortality rate and consumed food quantity. It is depended not only on the ability to elimination of these substances influence by the organisms. The effect of the diet with differentiated levels of manganese has been studied in laboratory conditions on caterpillars Cabera pusaria (Lepidoptera; Geometridae). Laboratory breading took place in Climacell chamber with controlled temperature, humidity, and lighting conditions. Three different contents of manganese in the diet of caterpillars was achieved by dipping of birch leaves (Betula pendula) in solutions of MnCl2.4H2O. We determined the statistical significant differences between the treatments in experiment in the amount of consumed food, the time of pupation, mortality rate of caterpillars. And significant differences were detected in unconsumed food, droppings and pupae. The increased concentration of manganese in the diet had a negative influence on the development of C. pusaria larvae and it can cause 100% mortality of caterpillars.
