This article identified the entomophagous species that are constantly feeding on alfalfa, and identified 27 species of entomophagous predominant species belonging to 7 families of entomophagous species of alfalfa pests. It was observed that these are the families Neuroptera, Aphelinidae, Syrphidae, Coccinellidae, Anthocoridae, Nabidae and, Miridae. According to the ratio of entomophages, the most populous families were identified as goldflies (Shrysopidae), khan beetles (Coccinellidae), and wild caterpillars (Miridae). Their populations formed diversity. Studies have been conducted on the use of parasite encarcation parasites in the management of whitefly population. It has been used in a variety of consumption norms against leachate in open and closed conditions. Encarsia (Encarsia partinopea Masi) was used to control the amount of whitefly (Trialeurodes vaporariorum) in greenhouse conditions. In the greenhouse conditions, 87.9% biological efficiency was achieved on day 28 after the application of encarcation in a 1:10 ratio in cucumber crops, and by the end of the season, parasitic entomophages were effectively controlling the amount of whiteflies. After 24 days of application in a 1:10 ratio in cucumbers planted in the open, the biological efficiency reached 83.5%. At 30 days after application, 86.5% biological efficacy was maintained.
