Table 3 Median lethal concentration (LC50) values for the indigenous strains of entomopathogenic fungi Beauveria bassiana and Metarhizium anisopliae bioassayed against late 3rd instar nymphs of peach-potato aphid Myzus persicae under laboratory conditions

From: Isolation, identification and virulence of indigenous entomopathogenic fungal strains against the peach-potato aphid, Myzus persicae Sulzer (Hemiptera: Aphididae), and the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae)
