Online published on 23 July, 2019. Abstract Field experiments were conducted at the Horticultural orchard, TCB College of Agriculture and Research Station, Bilaspur, Chhattisgarh during October-May 2015–16 to evaluate the population level of mango hoppers Amritodus atkinsoni and Idioscopus nagpurensis on varieties viz., Dashehari, Langra, Sundarja, Dilpasand and Himsagar. The hopper incidence was found to significantly vary among the varieties with minimum being with Sundarja (0.96/twig/panicle) followed by Himsagar (1.32/twig/panicle); and the one in Langra variety (2.56/twig/panicle) being moderate. Maximum incidence was observed with the variety Dashehari (3.20/twig/panicle) followed by Dilpasand (2.72/twig/panicle). Irrespective of the varieties, significantly more hopper population was observed during first fortnight of February.
