Chickpea is a significant cash crop for West Shoa farmers as it does for farmers in Ethiopia. Its production has been declining due to biotic and abiotic factors. One of the most important causes of grain loss in stored chickpea is the damage caused by Pulse beetle, Callosobruchus chinensis (L.). This study was conducted with the objective to evaluate the efficacy of available botanical extract at different rates against Callosobruchus chinensis, under laboratory conditions. The experiment was laid out in a Completely Randomized Design with three replications. The results revealed that there was an increasing trend in parent adult mortality over time, i.e., the highest C. Chinensis parent mortality of 100% were recorded from Guizotia abyssinica oil, Ricinus communis oil, Citrus lemon oil, and Azadiracta indica seed extract at the rates of 100mg, 75mg, and 50mg/kg of Chickpea on the fifth day after exposure to treatments. Phytolaca dodecandra seed, and Eucalyptus globules leaves caused 66.67%, 70.0%, and 71.11% mortality after fifth day exposure at the rates of 50mg, 75mg, and 100mg, respectively. The lower mortality of 58.89% and 51.11% were recorded from ‘Datura stramonium leaves and Schinus molle at a maximum rate on the 5th day of treatment exposure, respectively. It is concluded that the Guizotia abyssinica oil, Ricinus communis seed, and Citrus lemon oil were found to be the most potent bio-insecticides against C. chinensis. Therefore, these three botanicals are recommended as a safe alternative for the control of C. chinensis in stored chickpea.
