“…The virulence of different isolates of Beauveria bassiana increased with increase in spore concentration. Similar results were also obtained by Tefera and Pringle (2004a). The PAU Bb isolate of B. bassiana at all the test concentrations caused maximum mortality of C. partellus as compared to other test isolates.…”

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)

“…Therefore, they became infested with conidia which they carried into the plants. In addition, fungal infection can reduce food consumption by larvae (Tefera & Pringle, 2004). Application of these fungi may play a strategic role in the management of C. partellus, provided applications are made sufficiently early to target young larvae feeding in the leaf whorl.…”

“…The reason for the seemingly limited diversity within B. bassiana populations from agricultural systems in East Africa and the Caribbean compared to Europe could be related to the tropical climate or limited dispersal mechanisms within these regions. It has previously been reported that B. bassiana is effective when applied against arthropod pests that infest sugarcane [ 20 , 23 , 24 , 25 ] and the naturally occurring fungi may contribute to the regulation of pest populations [ 63 , 64 , 65 , 66 , 67 ].…”

“…Although B. bassiana and M. anisopliae are known to be effective against insect pests that infest sugarcane [ 20 , 23 , 24 , 25 , 26 ], few studies have focused on natural occurrence of entomopathogenic fungi in sugarcane cropping systems in Africa [ 24 , 27 ]. Ngubane et al [ 27 ] isolated Metarhizium anisopliae , Beauveria bassiana , Beauveria brongniartii , and Lecanicillium lecanii from various insect cadavers collected from sugarcane fields in six countries in southern Africa.…”

The natural occurrence of entomopathogenic fungal endophytes in sugarcane (Saccharum officinarum) and in soil samples from sugarcane fields was evaluated in Chikwawa District, southern Malawi. Fungi from soil were isolated by baiting using Galleria mellonella larva. Fungal endophytes were isolated from surface-sterilized plant tissue sections. Forty-seven isolates resembled the genus Beauveria, 9 isolates were Metarhizium, and 20 isolates were Isaria. There was no significant difference in the number and type of fungal isolates collected from soil and from plant tissue. There was, however, a significant difference in the part of the plant where fungal species were isolated, which fungal species were isolated, and the number of fungal species isolated at each location. Phylogenetic analysis of 47 Beauveria isolates based on DNA sequencing of the Bloc intergenic region indicated that these isolates all belonged to B. bassiana and aligned with sequences of B. bassiana isolates of African and Neotropical origin. The Malawian B. bassiana isolates formed a distinct clade. No larvae died from infestation by multiple fungi. To the best of our knowledge, this is the first report of B. bassiana and Isaria spp. occurring naturally as endophytes in sugarcane. Further, it is the first report of B. bassiana, Isaria spp., and Metarhizium spp. in the soil of sugarcane fields in Africa.
