A field study was carried out during 2018-19 to evaluate the population fluctuation of insect pests and their natural enemies in sunflower ecosystem. The data revealed that thrips and lepidopteran pests viz., head borer, Helicoverpa armigera and defoliator pests such as Spodoptera litura and Spilarctia obliqua were found to be the major insect pests during kharif season. Whereas, the sucking pests viz., leafhopper and whiteflies were found to be the major insect pests during rabi season.
