“…Besides Cordyceps , several studies on chemical analysis of yellow or red pigments of another entomopathogen genus Beauveria have been reported (El-Basyouni et al, 1968; Wat et al, 1977; Wraight et al, 1998). Fungal pigmentation has been related to pathogenicity in some pathogenic fungi.…”

Characteristic growth patterns of Cordyceps militaris isolates on various media, under varying light conditions and at varying incubation periods were examined. Light was found to be the most critical single factor in determining the density, texture, and pigmentation of the mycelial culture of the fungus. However, under the light condition, the degree of pigmentation and mycelial density were found to be affected by the incubation period and type of medium. Irrespective of the variations in medium type or incubation period, there was no pigmentation of the mycelium under dark condition. Radial growth of the mycelium was faster under dark incubation rather than under light incubation. Abundant mycelial density and darkest pigmentation of C. militaris isolates were produced in nutritionally rich media like SDAY, SMAY and CZYA, suggesting that these media may fulfill all the requirements for vegetative growth of the fungus. Growth characteristics of C. militaris isolates could be easily observed by the simple agar culture method, which would be useful to characterize the phenotypic characteristics of large number of pure cultures of the fungus under given conditions of growth factors such as medium, light and temperature.

“…However, in terms of mortality rate, there were no significant differences between concentrations of 10 7 and 10 8 and concentrations of 10 4 and 10 5 spore ml -1 . Among all antimicrobial agents, entomopathogenic fungi due to frequency in pathogenic races, broad host range and methods of pathogenicity can control a broad range of pests (Fan et al, 2007 (Shi and Feng, 2004), Chilo partellus (Swinhoe, 1885) (Tefera and Pringle, 2004), whiteflies (Wraight et al, 1998(Wraight et al, , 2000Ramos et al, 2000;Mascarin et al, 2013), Helicoverpa zea (Boddie, 1850), Spodoptera exigua (Hubner,1808), Spodoptera frugiperda (J.E.

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.
