Abstract:
Petroleum ether (Pet. ether), chloroform (CHCl3) and methanol (CH3OH) extracts of the test plant Aglaonema marantifolium (Schott.) have been subjected to dose-mortality and repellent activity tests against adult beetles of Callosobruchus chinensis (L.), Sitophillus oryzae (L.) and Tribolium castaneum (HBST.). The Pet. ether extract of A. marantifolium gave the LD50 values 1.04, 0.91, 0.87, 0.83, 0.80, 0.78 and 0.77mg/cm2 against S. oryzae; 1.34, 1.19, 1.14, 1.12, 1.07, 1.03 and 1.02mg/cm2 against T. castaneum; and the CH3OH extract gave the LD50 values 2.34, 2.15, 1.93, 1.86, 1.83, 1.82 and 1.81mg/cm2 against C. chinensis after 6, 12, 18, 24, 30, 36 and 42h of exposures respectively. The CHCl3 extract did not show any mortality against all the three test insects. In repellency tests, the CHCl3 extract was found to show significant repellent activity against the adult beetles of C. chinensis at 5% level of significance (P<0.05). However, Pet. ether and CH3OH extracts of A. marantifolium did not show repellent activity against any of the three test beetles.
