Studies on the field efficacy of gamma irradiated male M. vitrata (Fabricius) (Lepidoptera: crambidae) in comparison with chemical spray

In recent years Maruca vitrata is becoming predominant insect pest in all pigeon pea growing areas of India. It was controlled primarily through use of chemical insecticides. But their effectiveness is hindered by the tight larval webbing that reduces pesticide exposure. So an eco friendly or autocidal method is one of the best options. In an effort to continue the development of a sterile insect release program against the spotted pod borer, the present study was conducted in field cages, during flowering stage of the pegion pea crop, ten pairs of normal M. vitrata were released in all the four blocks. Later irradiated males release and multinemor 0.15 per cent spray was imposed each of them alone and in combination. Results suggest that efficacy of gamma irradiated male Maruca moths in comparison with multinemor spray indicated combined effect irradiated moths and multinemor at 0.15 per cent spray which recorded significantly lower incidence, pod damage and high grain yield as compared gamma irradiation or multinemor 0.15 per cent spray each of them alone.
