Summary:
Mango hoppers Idioscopus clypealis, I. niveosparsus, Amritodes atkinsoni (Cicadellidae: Hemiptera)
Lethierry (1889) first recorded mango hoppers from Saharanpur (UP). They are widely distributed in India, Malaysia, Indonesia and Thailand. No alternative host plants of these insects are known. Hoppers are active throughout the year, but abundant during hot months of May to June and cold months of October to January, synchronizing with flowering of mango trees. When inflorescence appears, hoppers start laying eggs in them. Female inserts eggs singly into flower buds and inflorescence stalk. It deposits on an average 200 eggs. Within 4 to 7 days, eggs hatch and nymphs commence feeding on the inflorescence, quickly suck the cell sap and excrete honeydew. This serves as a medium for the development of sooty mould fungus, giving dull blackish look to the mango trees. Nymphs become fullgrown in 8 to 13 days. The full-fed nymphs moult and give rise to winged hoppers. Life cycle from egg to adult takes 12 to 17 days. During a flowering season, two or more broods of the pest may occur. They occur in small numbers inside barks or on leaves of mango during non-flowering period.Number Of Quantity:
