Abstract : The mango-hopper, Amritodus atkinsoni (Leth.) (Jassidae: Hemiptera) is one of the most serious pests of mango trees in Manipur. The maximum infestation is seen during the (February and March) flowering season when the temperature is 28°C (Max.), 25°C (Min.); R.H. 85% (Max.), and 75% (Min.); Rainfall almost nil. During other months, they are very few in number and confine themselves in cracks and crevices of the bark of trees. The life cycle continues from February/March to April/May. The eggs are laid on rachis of inflorescence, having incubation period from 8 to 12 days. There are five larval instars with four moultings, the total nymphal period including five instars lasted from 15 to 20 days and the total life cycle from egg to adult ranged from 25 to 28 days under the laboratory conditions.
