Experimental analysis of potential use of land with high pollution hazards (roadside belts, spaces around thermo-electric power plants and opencast coal mines) for silkworm production has been continued. This paper analyses the effect of silkworm feeding on the foliage from the regions with various forms of pollution, on the realization of its biotic potential in small experimental populations. Based on the previously analyzed results on the productive characteristics of cocoons, the possibility of using polluted regions for the production of silkworm still remains open. The feed from the analyzed polluted regions exerted different effects on silkworm survival and reproduction potentials and existence of small experimental populations. Parent generation showed even some favorable effects (of the above parameters), but the effects were annulled and they became unfavourable in the filial generation.
