[Biological shedders of Opisthorchis cercariae (experimental research)]

To elaborate biological controlling measures and enhance the biological shedding [correction of bioeliminating] potential of biocenosis, 12 species of hydrobionts from 7 orders were tested for eliminating activity. The larvae of dragonflies and scale insects revealed the highest activity (eliminated from 67 to 77% cercaria). It has been established that, with the test exposition time of 3 hours, maximum elimination of cercaria takes place in the first hour of the experiment.
