A field experiment was conducted at Central Experimental Station, Wakawali, during rabi, 2018-2019 to study the effect of weather parameters on incidence of major pests infesting tomato. Whitefly, aphid and leaf miner appeared during 2^nd Standard Meteorological Week (SMW), while first incidence of fruit borer was seen on 5^th SMW. The peak population of whitefly were observed in 16^th SMW with a mean population of 7.83 per three leaves. Aphids (4.53 per three leaves) and leaf miner (40.02% infestation) were observed in 7^th and 12^th SMW, respectively. Whitefly, leaf miner and fruit borer demonstrated non-significant positive association with maximum temperature (r =0.319, 0.468 and 0.314, respectively), but non-significant negative correlation (r= -0.472) in aphids. Positive significant correlation was recorded (r= 0.521 and 0.571) of minimum temperature with whitefly and leaf miner, respectively. Whereas, non-significant negative correlation found (r= -455) between minimum temperature and aphid population. Fruit borer infestation had positive non-significant correlation (r= 0.450) with minimum temperature. The maximum relative humidity was non-significantly negative correlated (r= -0.429, -0.209, -0.498 and -0.484) with whitefly, aphid, leaf miner and fruit borer, respectively. Evening relative humidity showed positive non-significant correlation (r= 0.397, 0.384 and 0.407) with whitefly, leaf miner and fruit borer population, respectively. Aphid population was non-significantly negative correlated (r= -0.308) with evening relative humidity.
