Pathogenicity Of Iranian Isolates Of Metarhizium Anisopliae (Metschinkoff) (Ascomycota: Hypocreales) Against Trogoderma Granarium Everts (Coleoptera: Dermestidae), Adel Khashaveh

Adel Khashaveh

The Pathogenicity of Iranian isolates of Metarhizium anisopliae was evaluated against adults and larvae of Trogoderma granarium using immersion bioassay method. For each isolate, five aqueous suspensions were prepared in a logarithmic series from 1×105 to 1×109 conidia/ml. Each concentration was replicated four times. For each replicate, 30 adults or larvae were immersed in 5 ml of the suspension for 5 s. The entire assay replicated twice. All isolates were pathogenic to adults and larvae and mortality was elevated with increasing conidial concentration. Significant differences were detected among fungal isolates at different conidial concentrations. The cumulative mortality 10 days after …
