An experiment on utilization of biopesticides in the management of Apion amplum (Faust) (Apionidae: Coleoptera) was conducted at main research station, University of Agricultural Sciences, Dharwad during 2008-09. The results of present study indicated that among the microbial pesticides, Bacillus thuringiensis @ 1 ml/ l performed very well in reducing mean weevil numbers, pod and seed damage to greengram. This was followed by Beauveria bassiana 4 g/l and Metarhizium anisopliae 4g/l in reducing mean weevil numbers, pod and seed damage to greengram. B. thuringiensis treatment recorded highest grain yield 332.00 kg/ ha.Keywords
