Population dynamics of shoot fly Atherigona soccata Rondani was carried out at the Sorghum Research field, College of Agriculture, Indore, Madhya Pradesh during kharif, 2019-20. The incidence was assessed in terms of egg, deadheart, adult flies’ activity. The results revealed that the peak incidence was observed during 29th and 30th standard meteorological week (SMW). The fish meal trap correlation studies showed that shoot fly eggs, showed a positive and significant correlation with maximum temperature (r = 0.73). Every unit increase in maximum temperature, results in increase of 0.81 eggs/ 5 plants, while deadheart (r = 0.68) and adult flies (r = 0.79) showed positive significant correlation with minimum temperature. The regression analysis revealed that for deadheart and adult flies, with every unit increase in minimum temperature there was a increase of 16.30% deadhearts and 7.79 adults.
