Integrated pest management, in Available online 26 May 2010 which transgenic crops are strategically combined with rational pesticide use, may help to prevent H. armigera resistance acquisition in Bt cotton. In this study, we evaluated the toxicity of a novel insecticide Keywords: (chlorantraniliprole) on Cry1Ac-susceptible and resistant individuals of H. armigera. More specifically, we Chlorantraniliprole
