| Botanical compounds are increasingly investigated for their potential in pest control. Several botanical compounds, including essential oils (EOs), are recognized to affect the digestion and metabolic processes of insect herbivores. This study examines the effects of plant EOs on mortality, digestive physiology, and storage macromolecules of Ephestia kuehniella Zeller (Lepidoptera: Pyralidae). Oral toxicity of Cuminum cyminum and Anethum graveolens EOs were investigated against the fourth instar larvae of E. kuehniella. The LC50 and LT50 values were recorded 13.26 μL/mL and 15.28 h for C. cyminum and 6.15 μL/mL and 8.39 h for A. graveolens, respectively. In the present study, A. graveolens EO at lower concentrations and shorter times caused higher larval mortality. Activities of digestive enzymes, except for lipase, were significantly reduced in the insects fed on treated diet by both EOs. Additionally, the amounts of protein, triacylglycerol, and glycogen as energy reserves were markedly lower in the exposed insects, indicating depletion due to energetic costs imposed by this two EOs. The findings suggest that the A. graveolens EO is more effective than C. cyminum on the E. kuehniella larvae and disrupt critical digestive processes in, which may contribute to their insecticidal properties. However, further studies are needed to expand advanced plant derivative compounds-based encapsulation techniques to increase the stability, and efficacy. | ||
