The importance of predators and parasite species in integral control of tobacco aphids triggered us to investigate the qualitative and quantitative composition of the helpful entomofauna. In faunal investigations of predators and parasites of Myzus persicae Sulzer on tobacco, the following species were identified:
-Miridae (Hemiptera): Macrolophus costalis Fieber, 1858; Dicyphus pallicornis Fieber, 1861 and Deraeocoris (Camptobrochis) serrenus Douglas & Scott, 1868;
-Chrysopidae (Neuroptera): Chrysopa carnea Stephens, 1836; Chrysopa perla Linne, 1758; Chrysopa formosa Brauer, 1850; Chrysopa septempunctata Wesmael, 1841; Chrysopa nigricostata Brauer, 1850 and Notochrysa fulviceps Stephens, 1836;
-Coccinellidae (Coleoptera): Coccinella septempunctata Linnaeus, Coccinella quatuordecimpustulata Linnaeus and Adonia (Hippodamia) variegata Goeze
-Cecidomyiidae (Diptera): Aphidoletes aphidimyza Rondani, 1860
-Syrphidae (Diptera): Scaeva (Lasiopticus) pyrastri Linnaeus, 1758; Episyrphus balteatus De Geer, 1776; Eupeodes (Metasyrphus) corollae Fabricius, 1794; Sphaerophoria scripta Linnaeus, 1758; Sphaerophoria rueppelli Wiedemann, 1830 and Paragus quadrifasciatus Meigen, 1822.
-Aphidiidae (Hymenoptera): Aphidius ervi Haliday and Praon volucre Haliday.
During the three-year investigations, 5 predator families were identified, consisting of 30685 individuals, 5086 of which were Miridae, 26669 - Crhrysopidae, 10188 - Coccinellidae, 5336 - Cecidomyiidae, 7406 - Syrphidae, and one parasitic family Aphidiidae with 40482 individuals.
Quantitative composition of the investigated fauna is a sum of all stages of representatives of the families, i.e. a sum of eggs, larvae, pupae and adults, considering them all as real or potential predators-parasites of Myzus persicae Sulz. on tobacco.
In the scope of predator complex, Coccinellidae, Syrphidae and Cecidomyiidae were the most frequently represented families in all methods of investigation.
Growth of the population of predators and parasite species continuously follows the growth of aphids population, reaching its maximum in August. Our investigations confirmed that predators and parasites play an important bioregulatory role in the control of M. persicae on tobacco.
