Abstract

A field experiment was conducted at Entomology research field, IANS, Deen Dayal Upadhyaya Gorakhpur University, Gorakhpur during Rabi, 2022, for studying the seasonal incidence of insect pests infesting tomato. Serpentine leaf miner, aphid appeared during 46th SMW and whitefly, jassid during 48th   SMW, while fruit borer was observed during 2nd 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 evening relative humidity. Aphid incidence had a non-significant negative correlation with the evening relative humidity. However, all the insect pests showed non-significant correlation with the rainfall.
