The device made in this work refers, in particular, to devices for the mass reproduction of beneficial insects, and can be used for the growth of parasitoids (eggs, larvae, imago). The technical solution represents a device made in the form of a vertical cylinder. Holes drilled in the lower part of this cylinder, are covered with capron mesh with smaller cells than the size of the breeded insects. The air periodically pumped by a fan, ensures an uniform air circulation throughout the section of the maintenance chamber. The biological material is attached on tapes with labels. Later, these tapes are loaded into the maintenance room and fixed on the support in a vertical position, so that the optimal conditions for the development of insects can be ensured.
