To isolate, identify, and evaluate indigenous entomopathogenic fungi from Ethiopian soils to determine their virulence and feasibility as biological control agents.
Fungi were isolated from 120 soil samples collected across six Ethiopian localities using the Galleria baiting technique.
Isolates were screened in vitro for germination, vegetative growth rate, and sporulation, followed by molecular identification via ITS-rDNA sequencing.
Selected Beauveria bassiana and Metarhizium anisopliae isolates were tested against Galleria mellonella larvae to assess mortality rates and median lethal time (LT50).
Sixty-five isolates (54.2% recovery) were obtained; ITS-rDNA sequencing confirmed 7 as B. bassiana and 5 as M. anisopliae.
Selected strains achieved 86.67% to 100% larval mortality within 10 days, with 100% mortality observed in 4 (33.33%) B. bassiana and 2 (16.67%) M. anisopliae isolates.
Isolate B. bassiana AAUMB-29 exhibited the highest virulence with an LT50 of 2.36 days, closely followed by isolate AAUMFB-77 with an LT50 of 2.53 days.
