The aim of the current research work was to analyze the control potentials of plant extracts against stored product pests. The research work was carried out in the Crop Protection & Toxicology Lab, University of Rajshahi, Bangladesh, during April 2016 to November 2016. Pet. ether, CHCl3 and CH3OH extracts of Saraca indica L. were subjected to repellent activity and dose-mortality tests against Callosobruchus chinensis (L.), Sitophilus oryzae (L.) and Tribolium castaneum (Hbst.). Pet. ether extracts of root and stem bark; CHCl3 extracts of leaves, root and stem bark didn’t show mortality at all. However, other parts of the test plant extractives provided mortality to the test insects by yielding different LD50 values in different time exposure. In repellency test the extracts were found moderately repellent (P<0.01) and mild repellent (P<0.05). However, CH3OH extracts of leaves, CHCl3 and CH3OH extracts of stem bark didn’t show repellent activity at all.
