Metabolomic profiling of virulent and non-virulent Beauveria bassiana strains: insights into the pathogenicity of Tetranychus truncatus.

In this study, the pathogenicity of local Beauveria bassiana strains was elucidated using molecular and metabolomics methodologies. Molecular verification of the B. bassiana-specific chitinase gene was achieved via phylogenetic analysis of the Bbchit1 region.

A desirable substitute for chemical pesticides is mycopesticides. In the current investigation, rDNA-ITS (Internal transcribed spacer) and TEF (Transcriptional Elongation Factor) sequencing were used for molecular identification of six Beauveria bassiana strains. Both, leaf discs and potted plant bioassaye were carried out to study their pathogenicity against the cassava mite, Tetranychus truncatus.

is an entomopathogenic fungus that causes the white muscadine disease in insects. The majority of entomopathogenic fungi are soil and insect borne, 15 soil samples were collected from seven different locations during 2021, from January to December. Similarly, during 2022, March to December, 15 fungus-infected insect specimens were collected from five different locations hence soil and insect samples from various ecosystems were collected.
