Abstract: The aim of the present study was to report the bioagents feeding on Myzus persicae Sulzer (Hemiptera; Aphididae) in tobacco crop. Different species of predators from families Syrphidae
(Diptera), Coccinellidae (Coleoptera), Chrysopidae (Neuroptera) and Miridae (Hemiptera) were reported with different distribution, time of appearance and retention in tobacco cenosis. The representatives of Macrolophus spp. from family Miridae appeared earliest of all predators, already in the tobacco seedlings areas, and accordingly stayed on the plants longest, even in the absence of aphids. The highest density of the representatives of Macrolophus spp., followed by the species of families Coccinellidae and Syrphidae, and the lowest of the representatives of family Chrysopidae was recorded.
