Cowpea weevil ( Callosobruchus maculatus ) causes critical losses by affecting the quantity and quality of stored cowpea grains. The aim of this study was (a) to analyze peppermint ( Mentha piperita ) essential oil (EO) chemical constituents, (b) to explore its effects on the female and male adults, (c) to investigate whether exposure of parental generation (F 0 ) influences life table parameters and antioxidant enzyme activities in subsequent generations (F₁ and F₂). GC-MS analysis identified 52 volatile compounds in the peppermint EO, with isopulegol (26.613%), L-menthone (20.284%), cis-menthone (8.528%), eucalyptol (5.855%), camphene (5.754%), camphor (4.882%), and D-carvone (3.984%) as major constituents. The EO exhibited vigorous adulticidal activity, with males more susceptible (LC₅₀ = 1.894 ppm) than females (LC₅₀ = 3.349 ppm). Sublethal EO exposure significantly reduced fecundity and affected key life table parameters ( GRR , R0 , r , and λ ). Notably, LC₁₀ in F₁ and LC₃₀ in F₂ generations resulted in decreased GRR , R₀ , and r , while λ increased. Enzyme assays revealed substantial modulation of glutathione S-transferase (GST), catalase (CAT), and superoxide dismutase (SOD) activity, particularly at LC₃₀ and in the F 2 generation, indicating a possible oxidative stress response mechanism. These findings indicate that sublethal EO exposure can induce immediate and transgenerational physiological stress in C. maculatus , supporting the potential of peppermint EO as a botanical insecticide in sustainable pest management.
