ABSTRACT
The Khapra beetle Trogoderma granarium is a serious pest that infests stored grains worldwide, causing significant economic losses ranging from 6%-70%. For many years, its control has relied on chemical pesticides and fumigation, leading to the emergence of resistant strains and causing serious environmental damage. This study aims to evaluate the potential of certain plant extracts and essential oils as environmentally friendly alternatives for controlling the Trogoderma granarium insect. A comprehensive review of the scientific literature and previous studies was conducted, with a focus on recent research evaluating the efficacy of plant extracts against this stored – seed pest. The plant extracts and essential oils demonstrated strong efficacy against the insects, significantly increasing the incidence of adult insects and reducing egg-laying. Efficacy varies depending on the active secondary agents targeting specific physiological pathways. plant extracts represent an important and effective component for sustainability in integrated pest management, reducing reliance on chemicals while preserving the quality of stored seeds.
