Studies on population fluctuation of mango fruit flies at Saharanpur, Uttar Pradesh, revealed that population increased gradually from 5 flies in first week of February to 191 flies in the second week of September during 2007. Thereafter, population declined with decreasing temperature from fourth week of September (100 flies) and reached their lowest level in fourth week of December (1 flies) to first week of January (0.5 flies). The correlations of fruit flies population were positively significant with minimum temperature (‘r’=0.8108) and maximum temperature (‘r’=0.6061). However non-significant positive correlation was present with relative humidity (‘r’=0.1118).
