    • Abstract

       

      Brinjal (solanum melongena Linn.) leaves of varied maturity show a remarkable variation in respect to the retention of nutrient contents therein. The contents also vary along with the increase of plant age.Aphis gossypii Glover, an important pest of the crop, shows high reproductive potential on old and young leaves when the plants are young (2–4 months old) and mature (4–6 months old) respectively. Amongst the nutrient content of the leaves, nitrogen level shows a significant correlation with the reproductive potential of the aphid species leading to its population outbreak and niche selection.
