Abstract : The relative population of mango hopper species (Amritodus atkinsoni, Idioscopus niveosparsus and I. clypealis) on different cultivars of mango were recorded at Mir Ghulam Rasool Talpur Fruit Farm Tandojam, Sindh, Pakistan during year 2000. The cultivars screened for pest infestation were Sindhri, Langra, Sarolee, Dashehari, Swarnarika, Gulabkhas, Neelum, Zafran and Desi (indigenous). The results indicated that mango hopper species appeared on all cultivars from initiation of fresh flush of leaves/inflorescence during the last week of February with 1.94 individuals per shoot. The maximum mean seasonal population of 5.89 to 6.15 individuals per shoot was recorded from March to the first week of April. Second peak population 3.10 to 3.28 individuals per shoot was recorded during 3rd and 4th weeks of June. Thereafter, the mango hopper population declined up to harvest i.e., last week of July. The results further indicated that there was a statistically significant difference between cultivars and weeks. The Langra and Sarolee were relatively susceptible showing mean population of 5.65 and 4.91 individuals per shoot. Neelum (1.40), Zafran (1.72) and Dashehari (2.10) harbored less numbers of mango hoppers/shoot.
