Online published on 5 February, 2019. Abstract Syrphid flies on cauliflower when studied for population dynamics at Parbhani during rabi 2015–16 and 2016–17 revealed that their maggots were first observed in 50th meteorological week-MW (10–16 Dec. 2015–16) and in 51st MW (17–23 Dec. 2016–17). The peak activity was during 1st MW (1–7 Jan.) and 52nd MW (24–31 Dec.) in 2015–16 and 2016–17, respectively. The correlation of minimum temperature with population of maggots was negative and significant in 2015–16; it was positive and significant with population of aphids during 2015–16 and 2016–17. Buprofezin 25%SC and flonicamid 50%WG and cyantraniliprole 10.16%OD were found safer against syrphids.
