Abstract: Petroleum ether (Pet. ether), chloroform (CHCl3) and methanol (CH3OH) extracts of aerial part roots and seeds of Argemone mexicana L. were tested for their repellent potentials against Tribolium castaneum (Hbst.) and Aphis gossypii Glover adults. Against T. castaneum the CHCl3 extracts of the aerial part and roots offered moderate repellency at 1% level of significance (P<0.01), and the Pet. ether extract of the aerial part, root and seed gave mild repellency at 5% level of significance (P<0.05). While, against A. gossypii CH3OH extract of the aerial part showed repellency at 1% level of significance (P<0.01), while the Pet. ether and CHCl3 extracts of the aerial part and root; and the CH3OH extract of the root showed repellency at 5% level of significance (P<0.05); and none of the seed extracts gave repellency of A. gossypii at all. According to intensity of repellency the extracts of aerial part is more active than root extracts, and the seed extracts have very less repellent potential against both the test insects.
