Abstract: The experiment was conducted during rabi-summer season 2010-11 at Mango orchard, Department of Horticulture, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G). The thrips, Scitrothrips dorsalis and aphid, Aphis gossypii were recorded as major insect pests in chilli crop. The in festation of thrips began in the first week of February (5th Standard Meteorological Week) and reached to its peak in 3rd week of March. (12th SMW), that of aphid began in the first week of February (5th SMW) and reached its peak in the 2nd week of February (6th SMW). The abiotic factors of the environment i.e. evening relative humidity had significant negative correlation with the population of thrips. The aphid population was negatively correlated to minimum temperature and positively influenced by morning relative humidity.
