Abstract
It is demonstrated that it is important to take into account a number of factors when planning experiments on the studies of trophic indices of gipsy-moth caterpillars. These factors include first of all the population characteristics of the species - sexual and age structure changing annually. The final results of the investigation are also affected by some methodical approaches and features of experiments, in particular duration (especially in the long-run ages of caterpillars) and the amount of sampling, which must increase with an increase in the age of caterpillars. The reasonability of using individual breeding of caterpillars in the studies of nutrition of the species is considered.
