Greenhouse whitefly, Trialeurodes vaporariorum is a major pest of horticultural and ornamental plants and is usually controlled with insecticides or biological control agents. In the current study, we examined the effects of synthesized zinc oxide nanoparticles (ZnO NPs) and Beauveria bassiana TS11 on T. vaporariorum adults. ZnO NPs were synthesized by precipitation method. Field emission scanning electron microscope images indicated that ZnO NPs were noncompacted uniformly. X-ray diffraction results confirmed the hexagonal wurtzite structure of ZnO NPs. Fourier transform infrared analysis showed an intense absorption peak at a range of 434-555 cm -1 related to Zn-O bond. In bioassays, adults were exposed to different concentrations of ZnO NPs (3, 5, 10, 15, 20 , 10 7 , 10 8 spor ml -1 ). Vrednosti LC 50 so bile za nano delce ZnO 7.35 mg l -1 in 3.28×10 5 ml -1 za trose glive. Smrtnost, ki je bila dosežena pri največjih koncentracijah nano delcev ZnO in trosov glive je znašala 91.6 % in 88.8 %. Ti izsledki kažejo pozitivni učinek obeh pripravkov na smrtnost odraslih osebkov rastlinjakovega ščitkarja. Glede na to, da je bila raziskava opravljena v laboratoriju je potrebno v bodoče opraviti še več raziskav v realnih razmerah.
