The results of research on the cultivation of fodder plants of barley and infection of plants with cereal aphids in the conditions of an aeroponics installation are given. The germination parameters are determined depending on the periodicity of the water supply of its volume and the mass of the seeds grown in the plant. In the conditions of the aeroponic plant, the reproduction of aphids is considered optimal if 5 individuals of phytophagous are released per barley plant. After seven days, the number of aphids increased to 42.5 individuals, while its high concentration was noted. When carrying out the infection of aphids propagated under the conditions of the aphids, the optimal parasite ratio: host = 1: 60. The degree of infection of aphids (mummified) was 84.2% on this variant.
