Abstract
Study was carried out to evaluate the comparative efficacy of Amaranthus vitidis L. and Salsola baryosma (Schultes) and cypermethrin against Trogoderma granarium (Everts). Plant extracts were obtained by Rotary Shaker using ethanol as solvent. Twenty grubs of T. granarium (Everts) were exposed to three concentrations (0.5, 1.0 and 1.5%) for exposure periods of 24, 48, 72 and 168 hours. Experiments were carried out in an incubator at 30 ± 2°C and 65±5% R.H. Plant extracts [(A. viridis L. (19.58%) and S. baryosma (Schultes) (22.08%)] gave less mortality as compared to cypermethrin (37.64%). Percent mortality of T. granarium (Everts) increased both with the increase in concentration and exposure time. Keywords: Leaf extract, cypermethrin, Trogoderma granarium, efficacy
