Abstract : Population dynamics of mango mealy bug nymphs, Drosicha mangiferae Green were observed on the basis of seasonal abundance. Canopy in selected area were pinmarked as Tree-A, Tree-B and Tree-C and the number of nymphs of insect present on the tree trunk, terminal twigs or on inflorescences was recorded at an interval of a week. Population of insect was seen to be decreasing thereafter from mid February till last May on three trees. From the visual observations, it reveals that nymphs of mealy bug seen on trunks in the beginning were identified as first instar till mid February.
