Seasonal incidence of aphid, Aphis gossypii infesting cumin has been studied under field conditions at Research Farm, Agricultural Research Station, Mandor, during Rabi season, 2021-22. Observations on incidence of A. gossypii were recorded at weekly intervals from appearance of the pest till harvesting of the crop. The incidence started from first week of January (1st SMW) and continued till second week of March (10th SMW), peak occurred at second week of February (6th SMW) in cumin crop. Non significant correlation was observed between the A. gossypii population and weather parameters. Highest population of coccinellids was observed during second week of February (6th SMW) and showed highly significant positive correlation with aphid population
