The tobacco cutworm, Spodoptera litura (Fabricius) is a serious cosmopolitan pest that attacks several economically important crops such as maize, sorghum, chickpea, pigeon pea, cotton, and sunflower. It has developed resistance to most pesticides resulting in its continual outbreak. effect of caffeic acid on second instar larvae S. was evaluated by carrying out bioassays, nutritional assays, immune assays biochemical with phenolic acids. Bioassays carried showed growth inhibiting effects various concentrations (5 ppm, 25 125 625 ppm 3125 ppm) comparison control. A significant increase mortality well an increased development time observed the concentration acid. decrease indices, including relative rate (RGR), consumption (RCR), efficiency conversion ingested food (ECI), digested (ECD), approximate digestibility (AD), indicated dietary also negatively impacted physiology larvae. Caffeic impact immunological response As increased, overall number hemocytes decreased. Enzymatic revealed antioxidant enzymes when were given artificial diet containing LC50 for interval 24, 48, 72 96 h. levels oxidative stress markers (hydrogen peroxide, protein carbonyl lipid peroxide) significantly enhanced after treatment According our study, can be employed substitute traditional insecticides reduce population litura.
