The field experiment was conducted at Research Farm of the Department of Agricultural Entomology, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, Dist. Parbhani (M.S.) during the year rabi 2020-21 and 2021-22. The studies on the seasonal incidence during rabi 2020-21 and 2021-22 revealed that the population of safflower aphid started from 50^th MW and 51^th MW during rabi 2020-21 and rabi 2021-22, respectively. The peak of the safflower aphid population was noticed on 6^th MW and 5^th MW in both the seasons, respectively. The population of natural enemies viz., coccinellids and Chrysoperla observed in 51^th and 1^st MW during rabi 2020-21 and in 52^th and 1^st MW during rabi 2021-22, respectively. However, the peak coccinellids activity was noticed during 6^th and 5^th MW and that of Chrysoperla was observed during 6^th and 5^th MW of rabi 2020-21 and 2021-22, respectively.

Non-significant negative correlation was observed between maximum temperature, minimum temperature, morning relative humidity, rainfall and bright sunshine hours with the aphid population during the year 2020-21 and the correlation coefficient was -0.414, -0.341, -0.067, -0.365 and -0.036, respectively. Whereas, aphid population was positively non-significant (0.105) with the evening relative humidity.

During the year 2021-22, the correlations of aphid population with maximum and minimum temperature were significantly negative with correlation coefficients of -0.513* and -0.619**, respectively whereas non-significant positive correlations between morning relative humidity (0.368), evening relative humidity (0.262), rainfall (0.145) and bright sunshine hours (0.242).

There was non-significant negative correlation between maximum temperature, minimum temperature, morning relative humidity, rainfall and bright sunshine hours with the coccinellids population during first season 2020-21. Whereas, correlation of coccinellids population was positively non-significant (0.124) with the evening relative humidity. The correlations of coccinellids population with maximum and minimum temperature, morning relative humidity, evening relative humidity and rainfall were negatively non-significant during the year 2021-22 whereas non-significant positive correlation with bright sunshine hours (0.303).
