On the basis of equality of management cost and revenue of sunflower yield which was saved from pest damage as suggested by Stone and Pedigo (1972) [12] and further modified by Ogunlana and Pedigo (1974) [6], the Economic Threshold Level worked out for H. armigera on sunflower was 0.77 larvae/plant.
