Abstract : Recently, Helicoverpa armigera was recorded in most severe form, in mango orchards of Dharwad taluk and adjoining Kittur area, Belgaum District, Karnataka, India. The pest was observed in old orchards (12- to 15-year-old plants). The pest activity was restricted to only reproductive parts i.e. inflorescence and small fruits with larvae feeding on inflorescence leading to poor fruit set. Small fruits were partially fed by the larvae. The infestation level was 30-40%, and on average, each inflorescence had 0.75 to 1.00 larva. Since no annual host crops were found near the orchard, it is felt that infestation was due to the migration population of H. armigera.
