Abstract: To better understand the sublethal effects of insecticides (Spinosad, emamectin benzoate, thiodicarb, monocrotophos and fenvalerate) on Spodoptera litura, under eCO₂ and eTemp several studies were carried out to investigate the sublethal effects on the developmental stages and feeding indices of S. litura. The Relative Growth Rate, Relative Consumption Rate, Efficiency of Conversion of Digested food and Efficiency of Conversion of Ingested food decreased with increase in temperatures after exposure to sublethal doses (LC₁₀ and LC₃₀) of spinosad and fenvalerate . Contrastingly, higher feeding indices were recorded in the larvae treated with Emamectin benzoate, monocrotophos and thiodicarb.
