“…A teleomorph–anamorph connection was previously reported for B. brongniartii [ 71 ]. Currently, there are ten members of genus Beauveria , including B. pseudobassiana, that also have a confirmed sexual reproduction cycle [ 3 , 14 , 16 , 18 , 72 ]. Consistently, our testing of B. bassiana and B. pseudobassiana isolates revealed that sexual or parasexual recombination across NER is possible.…”

“…However, neither these methods nor ITS sequencing has provided sufficiently comparable data to infer interspecies and population genetic structures within Beauveria . Recent studies have been more consistent with the sequencing of nuclear intergenic locus Bloc being effectively mandatory for the determination of Beauveria phylogeny [ 3 , 24 , 25 ]. Most of Beauveria spp.…”

“…The genus Beauveria includes globally ubiquitous soilborne arthropod-pathogenic pleomorphic fungi belonging to Cordycipitaceae (Hypocreales) with high ecological and economical importance [ 1 , 2 , 3 ]. These fungi are important in the regulation of insect populations in natural environments, also occurring as saprotrophs and plant endophytes [ 4 ].…”

“…The natural insect host range of Beauveria spp. includes 17 orders of Arthropoda [ 3 , 26 , 27 ]. A number of studies have shown the lack of significant relationships between genotype and host specificity in Beauveria [ 28 , 29 , 30 , 31 , 32 ].…”

The distribution and genetic diversity of 91 of Beauveria isolates collected during a long-term survey in boreal forests of northern European Russia was studied. Based on morphological and sequence analysis of TEF and Bloc loci, three Beauveria spp. were identified: B. pseudobassiana, B. bassiana, and B. caledonica, with abundance of 81, 11, and 8%, respectively. Through multilocus sequencing, four haplotypes of B. bassiana and two haplotypes of B. caledonica were detected. Twelve haplotypes of B. pseudobassiana with non-random distribution were identified. Two haplotypes of B. pseudobassiana were the most abundant and widespread occurring across the whole study area, whereas others tended to be more specific to either the north or south of the study area, indicating the presence of different subpopulations. For further analysis of these putative subpopulations, southern and northern areas were separated along the boundary of the Köppen–Geiger climate zones (dfb and dfc), and the genetic structure was examined by analysis of molecular variance and spatial autocorrelation. Molecular evidence of intraspecific recombination of B. pseudobassiana and B. bassiana across northern European Russia area was indicated.

“…Morphological observations were performed using pure fungal cultures on potato dextrose agar (PDA) for two weeks at 25 ± 1 • C with a photoperiod of 12:12 h (Dark:Light). Macroscopic observations were determined through colony characteristics obtained by the shape, elevation, growth pattern, color, and texture [9,22,23]. Using a sterile needle, fungal structures were picked up and mounted in lactic acid on glass slides and observed using a compound microscope (ZEISS AX10) by the program ZEN 3.3 (blue edition) to observe hyphal conidiophore and measure conidial sizes.…”

Fall armyworm, Spodoptera frugiperda, entered Thailand in late 2018 and has now spread in several regions, with devastating effects in maize and rice production, which are some of the most important cereals in the world. Since then, farmers have utilized the available chemical insecticides to try to control it, but their efforts have been futile. Instead, they have ended up using extraordinary dosages, hence threatening non-target species and other fauna and flora, as well as being costly. In this regard, research has been ongoing, aiming to come up with eco-friendly solutions for this insect. We surveyed and collected various isolates of native entomopathogenic fungi intending to test their efficacy against fall armyworm. Six isolates of entomopathogenic fungi were obtained and identified to Beauveria bassiana based on morphological characteristics and multi-gene phylogenetic analyses. Thereafter, the six isolates of B. bassiana were used to perform efficacy experiments against fall armyworm. Additionally, the glycosyl transferase-like protein 1 (GAS1) gene was analyzed. Consequently, all the isolates showed efficacy against S. frugiperda, with isolate BCMU6 causing up to 91.67% mortality. Further, molecular analysis revealed that all the isolates possess the GAS1 gene, which contributed to their virulence against the insect. This is the first report of utilizing native entomopathogenic B. bassiana to manage S. frugiperda in Thailand, with the revelation of GAS1 as a factor in inducing virulence and cuticle penetration. This study has provided valuable information on the potential development of Beauveria bassiana as an eco-friendly bioinsecticide for the management of fall armyworm in Thailand.
