Abstract : Erosomyia mangiferae Felt (indica Grover & Prasad), an important pest of mango in India, first attacks the vegetative shoots that appear in late November and early December, with the result that some shoots soon dry up. It then attacks the newly forming inflorescence buds, some of which are lost. Although attack at this stage is not very injurious, it does assist in the build-up of populations of the cecidomyid. The axis is then galled, becoming stunted and variously deformed; losses at this stage, although usually negligible, can sometimes be important. Oviposition takes place in the open flowers, the newly hatched larvae entering the ovules. Practically every flower may be infested, so that losses can reach 100%. The reproductive potential is such that one pair of adults emerging in late November or early December could give rise to over 6 million females in early March, each laying 100 eggs in the flowers.
