Compatibility of entomopathogenic fungi and Azadirachta indica extract against the cotton pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae) under controlled conditions
Abstract Compatibility of entomopathogenic fungi (EPFs) viz. Verticillium lecanii, Metarhizium anisopliae and Beauveria bassiana with Azadirachta indica extract (alone and in combinations) was evaluated against 2nd instar larvae of the cotton pink bollworm, Pectinophora gossypiella (Saunders) (Lepid...
