Bioefficacy of Metarhizium anisopliae (Metschn.) Sorokin culture filtrates from different liquid media against Aphis craccivora (Koach) under laboratory condition

Abstract

The present study was undertaken to find out the bioefficacy of culture filtrates M. anisopliae from different liquid media against A. crassivora under laboratory condition during the year 2015-2017 in the Agricultural Entomology Department, College of Agriculture, Dapoli (Maharashtra). In this regards, green muscardine fungus, M. anisopliae was tested against aphid, A. craccivora. In this experiment, total nine liquid broth treatments were evaluated viz., Coconut water, Carrot broth, Potato dextrose broth, Coon’s medium, Corn flour medium, Czeapeks medium, Molasses, Gram flour medium and control (sterilized distilled water), respectively. The highest mean mortality of A. craccivora 86.67 per cent was recorded in treatment T6- Czeapeks medium which, was at par with T1- coconut water (83.33%). No mortality was revealed in control treatment.
