The present research was undertaken to study the diversity and economic status of Lepidopteran insect-pest on two major varieties of mango viz., Totapuri and Alphonso during 2014-15 in mango orchards of the Indian Institute of Horticultural Research (IIHR). In this study biodiversity of lepidopterans on mango ecosystem, there were a total of 13 lepidopteran species recorded. In both the varieties, Orthaga exvinacea, Chlumetia transversa, Dudua aprobola, Anarsia sp. and Nanguna sp., were the serious Lepidopterans both on vegetative and reproductive parts of the tree. However, on the basis of the level of infestation, D. aprobola, which damage both tender leaves and new panicles proved to be the most serious Lepidopteran pest of mango.
