Effect of gamma radiation on Phenoloxidase pathway, antioxidant defense mechanism in<i>Helicoverpa armigera</i>(Lepidoptera: Noctuidae) and its implication in inherited sterility towards pest suppression

Abstract

Irradiation impact on stress-indicating molecular responses in F1 progeny is correlated with its reproductive performance. These observations will permit defining regimen having pragmatic viability of 'F1 sterility technique' for pest suppression. Gamma dose of 100 Gy would ensure balance between induced sterility of males and their field competitiveness. These parameters would facilitate integration of biocontrol strategy with parabiological 'Sterile Insect Release Technique'.
