Abstract

Beauveria bassiana (Bals.) Vuill and Metarhizium anisopliae var. anisopliae (Metsch.) Sorkin when grown at temperatures of 25 and 30°C recorded maximum biomass, mycelial growth, conidial count and conidia. At these temperature they were highly Infective against Odontotermes brunneus Hagen. At temperatures below 25°C and above 30°C there was marked and significant reduction in the biometric characteristics and infectivity.
