The role of natural regulators of the number of brown-tail moth and their significance in the dynamics of the pest population has been studied. In the course of a statistical analysis of the influence of factors of the biotic environment on older caterpillars, an inverse relationship was established between their numbers and survival in a given age range. This is important for the subsequent application of the obtained data in the practice of plant protection.
