Chloroform and Methanol Extracts Against Tribolium Castaneum (Herbst) Adults JF - Journal of Life and Earth Science JA - J Life Earth Sci VL - 8 IS - 0 SE - Articles DO - 10.3329/jles.v8i0.20134 UR - https://banglajol.info/index.php/JLES/article/view/20134 SP - 11-15 AB - <p>The chloroform and methanol extracts of the leaves, root wood, stem bark, stem wood and seeds of <em>Abroma augusta </em>(L.) (Ulatkambal) were tested against <em>Tribolium castaneum </em>(Herbst) adults through residual film assay. The seed extracts (CHcl<sub>3</sub> and MeOH) were found to offer the highest mortality of the beetles and the LD50 values were 3046.083, 247.9217 and 75.96001 ?g/cm<sup>2</sup> and 6598.793, 340.4855 and 113.6461 ?g/cm<sup>2</sup> for the (CHCl<sub>3</sub>50 values of 1127.785, 312.5822 and 146.3708 ?g/cm<sup>2</sup> and 1689.468, 449.8259 and 134.9692 ?g/cm<sup>2</sup> for the (CHCl<sub>3</sub>350 values of 3466.807, 450.3049 and 175.7438 ?g/cm<sup>2</sup> and 4654.238, 1010.538 and 333.7202 ?g/cm<sup>2</sup> for the(CHCl<sub>3</sub>350 values of 3295.859, 1137.558 and 363.1539 ?g/cm<sup>2</sup> and 3717.851, 566.2215 and 230.7044 ?g/cm<sup>2</sup> for the (CHCl<sub>3</sub>3A. augusta did not show any activity against the beetles. According to the intensity of activity observed through mortality of the adult beetles the potentiality of the chloroform extracts could be arranged in a descending order of seeds&gt; root wood &gt; leaf&gt; stem bark and for the methanol extracts, seed&gt;root wood &gt; stem bark &gt; leaf.</p> <p>DOI: <a href="http://dx.doi.org/10.3329/jles.v8i0.20134">http://dx.doi.org/10.3329/jles.v8i0.20134</a></p> <p>J.
