The experiment was conducted on leaf miner, Acrocercops syngramma (M.) infestation and its parasitoids in Saeed Khan Kanher, mango orchard, Khairpur Sindh, Pakistan, during 2015. The results revealed were significant, (P<0.05) highest leaf miner larval population was recorded on Chaunsa (15.806/shoot). The leaf miner remained active during the emergence of new flushes in plants from August to October, with four population peaks. However, two parasitoids, Chrysocharis nephereus (W.) and Sympiesis hyblaeae (S.) were recorded in leaf miner larvae. The high adult’s population of parasitoids; C. nephereus and S. hyblaeae (4.502/plant and 1.767/plant) recorded on Chaunsa and minimum on Sindhri. While, significantly maximum parasitism percentage of both parasitoids C. nephereus and S. hyblaeae were recorded on leaf miner larvae on Chuansa. The correlation results of temperature and relative humidity with leaf miner populations on different mango varieties showed non-significant and negative correlation on Chaunsa, Fajiri and Sindhri.
