The device is used in plant protection for biological control of harmful insects. It fully uses the reproduction potential of the parasites, their automatic batching is attained, and the whole propagation and breeding cycle is mechanized without their being traumatized. The device includes table tops on which boxes for mass propagation are fitted opposite to each other by their internal perforated long sides, connected by guiding bands and a driving pressing element. A cassete for parasitization is positioned amongst the boxes and a conveyor belt limited by both its long sides by guiding bands, and the boxes are interconnected by a pneumatic duct with parasite batcher.
