We have found 28 brac<strong>on</strong>id species from 18genera <strong>on</strong> 21 phytophagous insects form 4 orders: Coleoptera, Homoptera,Hymenoptera <strong>and</strong> Lepidoptera. Registered brac<strong>on</strong>id species bel<strong>on</strong>g to: Aphidiinae,Brac<strong>on</strong>inae, Doryctinae, Euphorinae, Histeromerinae, Microgastrinae, Orgilinae <strong>and</strong>Rhogadinae. Although most <strong>of</strong> <strong>the</strong> registered phytophagous insects pose asignificant threat to Betula species, <strong>the</strong> two species: Epirrita autumnata <strong>and</strong>Lymantria dispar are <strong>the</strong> most important because <strong>the</strong>y can defoliate entire forestswhen <strong>the</strong>ir populati<strong>on</strong>s are in gradati<strong>on</strong>. There are two buprestid pests Agrilus anxiusnative to North America <strong>and</strong> A. planipennis from Central Asia which are c<strong>on</strong>sideredas potentially invasive species.Tr<strong>of</strong>ičke asocijacije insekata štetočina na topolama(Populus spp.) i brak<strong>on</strong>idnih parazitoida (Hymenoptera:Brac<strong>on</strong>idae) na teritoriji Srbije i jugoistočne EvropeIlić, M., Žikić, V., Stanković, S.Prirodno-matematički fakultet Univerziteta u Nišu, Nis, <strong>Serbia</strong>marijanailic83@yahoo.comZa ovo istraživanje izabrali smo topole (pre svega vrste Populus tremula i P.alba, zbog toga što su <strong>on</strong>e autoht<strong>on</strong>e za područje Vlasine) kao biljke hraniteljke zamnoge fit<strong>of</strong>agne insekte.

Štetočine koje napadaju topole pripadaju sledećim redovima:Coleoptera, Diptera, Hemiptera, Hymenoptera i Lepidoptera. Pored autoht<strong>on</strong>ih vrstatopola (Populus alba, P. nigra i P. tremula) za Srbiju, prikazane su tr<strong>of</strong>ičkeasocijacije i na vrstama Populus euphratica, P. deltoides i gajene vrste Populus x125
