Differential Activities of Antioxidant Enzymes, Superoxide Dismutase, Peroxidase, and Catalase vis-à-vis Phosphine Resistance in Field Populations of Lesser Grain Borer () from India.

Susceptibility to phosphine was compared in 15 populations of lesser grain borer () collected from grain storage godowns across India. A high level of resistance to phosphine was noticed in collected from northern India compared to those collected from northeastern regions of India. The median lethal concentration values varied from 0.
