Impact of Allium sativum on Callosobruchus maculatus Adult Emergence, Egg Laying and Protectant Potency of Stored Cowpea

Abstract
Pulses are considered a great protein source in Asia and the majority of other developing countries around the world. Post-harvest damages and quality impairment due to storage pests pose a significant challenge for agricultural communities in Middle East countries. As a replacement for the constructed pesticide and bulb oil extract of garlic, Allium sativum (L.) was examined contra the cowpea pest Callosobruchus maculatus. To determine the mortality percentages of cowpea beetles, as well as the oviposition, adult appearance, level of seed rotten, and Weevil Perforation Index (WPI), we mixed garlic powder at proportions of 1, 3, and 5/20 g of black-eyed peas, and used the acetone extract of garlic bulbs at 1, 2, and 3 ml for each 20 g of cowpea seeds. Three days into the treatment, 60.7%, 73.3% and 100% of the adult death in Callosobruchus maculatus was triggered by 1, 3, and 5/20 g of black-eyed peas, respectively. After three days of treatment, black-eyed peas died at every concentration of garlic bulb extracts. In both the powder and bulb extracts of garlic, complete preservation of seeds and prevention of adult apparition were noted. The current study proved that both powder and garlic bulb extract successfully inhibited the effect on cowpea beetles, C. maculatus, in stored black-eyed peas.
