Role of morphological traits viz., okra leaf, nectariless, glandless, red pigmented and frego bract developed in the common genetic background of cotton (Gossypium hirsutum L.) variety H-777 as isogenic lines were studied in relation to insecticidal control of major insect pests of cotton at Research Farm, CCS Haryana Agricultural University, Hisar, India. Okra leaf and frego bract increased the efficacy of insecticides against bollworms by reducing bollworms incidence and damage. But these traits were found to be associated with lower yields. On the other hand, these morphological characters did not influence the efficacy of insecticides with respect to leafhopper, a sap sucking pest
