Mango (Mangifera indica)
Mango Hoppers (Dioscopus niveoparsus,I. clypealis, Amirtodus atkinsoni)
Symptoms
- Nymphs and adult insects puncture and suck sap of tender parts, reducing vigour of plant especially the inflorescence and cause fruit drop.
- Heavy puncturing and continuous draining of sap causes curling and drying of infested tissue. They also damage the crop by excreting a sweet sticky substance which facilitate the development of sooty mould.
Management
- Avoid dense plantings, prune overcrowded overlapping branches
- Orchards should be kept clean by regular ploughing and removal of weeds.
- Spraying of 0.2% Nimbicidin or Azadirachtin 3000 ppm@2m/l at initial stage of hopper population
