Abstract

The influence of host plant on the number of Lepidopteran phytophagous insects and their susceptibility to the biological preparation on cabbage subspecies and cultivars was studied. Under the field conditions, red and write cabbage subspecies were preferable for diamondback moth larvae, whereas cauliflower and white cabbage were preferable for large white butterflies larvae. The differences is the efficacy of bacterial entomopathogenic preparation used for phytophage biocontrol depending on cabbage subspecies were discovered. Biocontrol efficacy was higher on host plants that showed better resistance to phytophagous insects.
