“…Mortality of older instars occurs via infection from mycosed cadavers inside the stem. 30 Similar effectiveness of M. anisopliae was recorded by Nguyen et al 31 in their laboratory bioassays, against the various larval instars of Helicoverpa armigera Hübner (Lepidoptera: Noctuidae). In the current experiment, a dose-dependent upsurge in mortality is corroboratory to the study of Sasidharan and Varma, 32 who reported higher larval mortality of Indarbela quadrinotata Walker (Lepidoptera: Cossidae)-up to 100% -when treated with higher doses of Beauveria bassiana (Bals.-Criv.)…”

Susceptibility of Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) populations to Metarhizium anisopliae and Bacillus thuringiensis (Bt) were evaluated under laboratory conditions. T. absoluta larvae were treated either individually or in combination with a single dose rate of B. thuringiensis (0.5 μL/L) and three conidial suspensions viz. 1x104, 1x106 and 1x108 spores/mL of M. anisopliae. Larval mortality, pupation, adult emergence, mycosis and sporulation varied depending on the application of different quantities of M. anisopliae alone and in combination with B. thuringiensis. Maximum mortality (100%) was achieved in 2nd instar larvae when M. anisopliae (1x108 spores/mL) and B. thuringiensis (0.5µL/L) were applied synergistically,while 4th instar larvae recorded a 95.45% mortality. Compared with the untreated checks, mortality, pupation and adult emergence of both 2nd and 4th instar larvae were significantly reduced with the combined application of M. anisopliae (1x108 spores/mL) and B. thuringiensis (0.5µL/L). Μycosis was most prevalent on 2nd and 4th instar larvae, exceeding 88 and 80% respectively,after exposure to 1×104 conidia/mL. The results indicate that the entomopathogenic fungi and the insecticidal protein produced by B. thuringiensis can be used in combination as biocontrol agents for the management of T. absoluta.

“…The plants in the infested control treatment exhibited minimum leaf injury (4.00%) but maximum deadhearts (84.00%) incidence and maximum LIR (8.48) of C. partellus. The lower LIR values in the B. bassiana isolates as compared to infested control treatment might be due to reduction in feeding of C. partellus larvae infected with B. bassiana, which has already been reported by different workers (Tefera and Pringle, 2004b).…”

“…Although, the deployment of chemical control at right time is fairly successful for the management of this pest, but excessive use of chemicals can lead to many ecological problems. Therefore, an alternative control measure such as biological control with Beauveria bassiana Balsamo (Vuillemin) which has been reported to naturally regulate the populations of C. partellus in laboratory bioassays as well as in field experiments (Maniania,1993;Devi et al, 2001;Tefera and Pringle, 2004b) must be evaluated against C. partellus. But different isolates of B. bassiana differ in their host specificity and virulence (Mc Coy et al,1988) and it has been reported that the native species of natural enemies always most fit as they are adapted for the local agro climatic conditions and ecosystem (Smith, 1996).…”

Biocontrol potentiality of Beauveria bassiana Balsamo (Vuillemin) against Chilo partellus (Swinhoe) under controlled conditions ABSTRACT: Eight different isolates of Beauveria bassiana Balsamo (Vuillemin) were evaluated for their efficacy or biocontrol potentiality against Chilo partellus (Swinhoe) under controlled conditions at Punjab Agricultural University, Ludhiana. The results of the present studies revealed that all the eight isolates irrespective of their original host were pathogenic to C. partellus. The virulence of the isolates was increased with increase in spore concentration. As compared to other isolates, the native isolate of B. bassiana, PAU Bb and Bb 4668 caused higher mean mortality of C. partellus (68.75 and 56.25 %) at the concentration of 1 × 10 10 spores/ml. These isolates were 56.49 and 7.17 times more pathogenic than the commercially available isolate of B. bassiana. Under screen house conditions, the efficacy of B. bassiana isolates, against C. partellus was comparatively lower than Decis 2.8 EC deltamethrin. However, the application of B. bassiana resulted in lower incidence of C. partellus than infested control. * Mean of 5 replications ** Figures in parentheses are mean of arc sine √ percentage transformed values *** Figures in parentheses are mean of interpolated transformed values (ITV) according to Fisher and Yates (1976)

“…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.
