An experiment was conducted at the Agricultural Research Farm, Banaras Hindu University, Varanasi, Uttar Pradesh, India from November 2019 to March 2020 at eight locations. The experiments were conducted for seasonal responses of Chrysanthemum aphids and thrips. The first incidence of aphids on chrysanthemum plants was observed in the month of November at 46th Standard meteorological week (SMW) and attained its peak in January at 4th SMW. In the case of flower thrips, the first incidence was observed on 46th SMW and attained its peak at 4th SMW. The correlation analysis of aphids with weather parameters exhibited a significant negative correlation with temperature (minimum, maximum and average) whereas, negative and non-significant correlations were found with humidity (morning, evening and relative) and rainfall. The correlation analysis of thrips with weather parameters exhibited a significant negative correlation with temperature (minimum, maximum and average), whereas, it showed a negative non-significant correlation with morning relative humidity, average relative humidity and rainfall, but a non-significantly positive correlation with evening relative humidity.
