<br/><br/> Five insect growth regulators (IGR's)were tested to increase the susceptibility of the cotton leaf worm spodoptera littoralis (Boisd.) (Lepidoptera : noctuidae) to its homologous nucleopolyhedrovirus (SpliMNPV)Spodoptera littoralis MNPV was tested alone or in combination with IGR's at LC ₁₀ level against the second instar larvae of the pest
