Efficacy of Two Entomopathogenic Fungi in Combination with Diatomaceous Earth Against Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae)
The current investigation was conducted to study the efficacy of natural diatomaceous earth (DE) alone and combined with two fungal pathogens: Metarhizium anisopliae and Beauveria bassiana , as a new formulation against Spodoptera littoralis third instar larvae under laboratory conditions. When M . anisopliae , B . bassiana , and DE were applied alone, the mortalities of larvae were concentration-dependent. The LC 50 values were 299.2, 391.5
