Serpentine leaf miner, aphid appeared during 46 th SMW and whitefly, jassid during 48 th SMW, while fruit borer was observed during 2 nd SMW. Correlation study revealed that Serpentine leaf miner, whitefly, aphid, jassid and fruit borer witnessed significant positive correlation with the maximum temperature and minimum temperature. Serpentine leaf miner and fruit borer recorded negative non-significant correlation with the morning relative humidity and evening relative humidity. Whitefly, jassid and aphid population had significant negative correlation with the morning relative humidity. Whitefly and jassid population registered a significant negative correlation with Original Research Article
