The present study was carried out to evaluate the effects of the lethal dose (LC50) of abomectin and two IGRs on cotton leafworm Spodoptera littoralis from the point of biochemical aspects. The relative susceptibility of two strains of the pest (laboratory and field strains) to three insecticides: i.e., diflubenzuron, pyriproxyfen and abamectin, was tested using dipping technique. Values of the LC5o were calculated for each compound. The tolerance ratio was determined on hasis of the LCsIJ values of the two tested strains.
