Abstract
The predator Podisus maculiventris Say is a representative of the order Hemiptera, family Pentatomidae. This insect is promising in the battle against the Colorado potato beetle Leptinotarsa decemlineata Say. For the successful use of P. maculiventris in the climatic conditions of the Russian Federation and other countries where this predator isn’t found, it is necessary to develop methods of its artificial reproduction. The paper provides information on the selection of food based on the use of phytophagous insects and pests. Among the subjects Galleria mellonella L. caterpillars, Tenebrio molitor L. larvae and pupae, Ephestia kuehniella Zll. caterpillars, as well as Zophobas morio Fabr larvae were used. As a result of the experiment, T. molitor was recognized as the most effective insect prey in terms of biological and economic indicators. When using Tenebrio molitor, the imago yield of P. maculiventris amounted to 81.0-90.5%, which was the best indicator in comparison with other options.

Summary
Leptinotarsa decemlineata Say is a dangerous potato pest on the territory of many countries, including the Russian Federation. Podisus maculiventris Say is a predator of many insect pests [1,2,3], including Leptinotarsa decemlineata Say. P. maculiventris is an endemic species of North America: it is found from the southeastern part of Canada (Quebec) to the southeastern part of the United States of America (Florida). P. maculiventris is an endemic species of North America: it is found from the southeastern part of Canada (Quebec) to the southeastern part of the United States of America (Florida) Inhabiting various biotopes, it plays a significant role in regulating the number of many pests of forest, garden and agricultural crops in North America [4]. The adults enter diapause and spend the winter in such shelters as forest litter, tree bark, tree stumps, and building cracks
