Gypsy moth (Lymantria dispar L.) growing on different feeding substrates was shown to affect their susceptibility to nuclear polyhedrosis virus (NPV). The insects feeding on birch leaves had the lowest sensitivity to NPV than those on willow leaves, but the insects growing on pine needles showed the highest susceptibility. The sensitivity of the gypsy moths on willow leaves was higher than that of the gypsy moths on birch leaves and lower than that of those on pine needles. At the same time, it did not differ from that of the caterpillars on artificial feeding. The virus polyhedrons formed in the caterpillars on birch or willow leaves were more than those on another fodder.
