This research aims to clarify the mechanisms behind sesame's resistance to the pest Antigastra catalaunalis.
Evaluated thirteen sesame genotypes for resistance traits including morphology and physiology.
Measured factors like foliar damage, larval establishment, and antibiosis in response to pest infestation.
Used multivariate analyses, including principal component analysis and K-means clustering, to discriminate genotypes.
Resistant genotypes displayed reduced feeding injury and larval settlement, with lower oviposition preferences.
Higher trichome density and increased specific leaf weight correlated with better resistance outcomes.
Elevated activities of antioxidant enzymes and redox metabolites indicated stronger oxidative stress regulation in resistant genotypes.
