Abstract
This study has been conducted to knowing the effect of different concentration of alcoholic extract 2,4,12% and the cold aqueous extract 12,15,25, 23% of the fruits of Melia azedarach on the ability of the adults of Oryzaephilus surinamensis to penetrate the filling sacks (jute and poly propline)and on them the loss percentage in the seeds rice weight of the stored grains. Aqueous have shown the lowest percentage of losing weight of the seeds that were sacked in poly propline sacks that where treated with the alcoholic extract at the concentration of 12% which was 1.88% where by the cold watery extract has given the lowest percentage of losing weight of the sacked seed at the concentration of 35% which was1.02%after six months of storage when treaded jute sacks with insecticide actellic at concentration 0.01% (recommend concentration) has given the lowest percentage of losing weight of sacked seed was 0.36% after 6 months of treatment. Therefore we suggest using the treated with the alcoholic extract at the concentration of 12% weight of the sacked seed at the concentration of 35%.
