Petroleum ether (Pet. ether), chloroform (CHCl3) and methanol (CH3OH) extracts of Epipremnum aureum (Linden & Andre) G. S. Bunting have been subjected to dose-mortality and repellent activity tests against the adult beetles of Tribolium castaneum (Hbst.), Sitophilus oryzae (L.)and Callosobruchus chinensis (L.). The Pet. ether extract of E. aureum gave the LD50 values 1.40, 1.21, 1.16, 1.10, 1.04, 0.96 and 0.84mg/cm2 against T. castaneum; 1.73, 1.66, 1.32, 1.08, 1.00, 0.99 and 0.90mg/cm2 against S. oryzae; 2.95, 2.02, 2.01, 1.91, 1.82, 1.72 and 1.65mg/cm2 against C. chinensis after 6, 12, 18, 24, 30, 36 and 42h of exposures respectively. CHCl3 and CH3OH extracts did not show any mortality against all three test agents. In repellency tests, Pet. ether extract of E. aureum showed significant repellent activity against T. castaneum and C. chinensis at 5% level of significance (P<0.05); CHClÂ3 extract showed significant repellent activity against T. castaneum and C. chinensis at 1% level of significance (P<0.01) and at 5% level of significance(P<0.05) respectively. However, the CH3OH extract of E. aureum did not show repellent activity against T. castaneum, S. oryzae and C. chinensis.
