Open publisher page 4 citations

Abstract

Both petroleum ether and chloroform extract of A. indica showed maximum antifeedant activity against T. castaneum and T. granarium. The repellency (%) of E. officinalis against T. castaneum was maximum at 1% conc. after 3 hours of treatment (86.61%) with a mean PR of 66.66%. however 1% conc. of E. officinalis against T. granarium was least effective (5.33). E. officinalis gave best result at 2% conc. with a mean PR value of 77.33%.
