JF - Al-Mukhtar Journal of Sciences JA - MJSc VL - 35 IS - 2 SE - Research Articles DO - 10.54172/mjsc.v35i2.326 UR - https://omu.edu.ly/journals/index.php/mjsc/article/view/326 SP - 166-175 AB - <p>This study aims to test the biological effect of three plant powders of (black pepper fruit <em>Piper</em> <em>nigrum</em> L., nutmeg seeds <em>Myristica</em> <em>fragrans</em> Houtt and bay leaf <em>Laurus</em> <em>nobilis</em> L.) when mixed with wheat flour at concentrations of; 0.2, 0.5, 0.75, 1 and 1.5 % (w/w) against the confused flour beetle <em>Tribolium</em> <em>confusum</em>. Results showed that the black pepper fruit caused a decrease in the production of larvae that reached 65.36%, while the nutmeg seeds powder caused a decrease of 50.93% compared with the bay leaf powder, which caused a decrease of 38.20%. The results also showed a decrease in the first generation progeny (F1) that reached 90.75% and 75.34% due to the treatment with the black pepper fruit and the nutmeg seeds powders respectively. However, the bay leaf powder was less effective, with only a decrease of 30.13%.</p> ER -
