The experiment was carry out at Farmer’s field near Shaheed Zulfiquar Ali Bhutto Agricultural College, Dokri Larkana, Campus of Sindh Agriculture University, Tandojam Pakistan for evaluating the Brinjal Fruit and Shoot Borer (Leucinodes orbonalis G.) population fluctuation under field conditions throughout year 2019-20. Brinjal shoot and fruit borer (L. orbonalis G.) population started developing in the last week of May 2019 and observed throughout the year. High temperature favor the population development; maximum damaged fruits were observed in the month of September 2019 (11.75), maximum larva inside damaged fruits were observed in the month of June 2019 (85.18%) population started decreasing as the temperature started going down. Minimum damage was recorded 2.40% in the month of February 2020minimum larva inside fruits was recorded in the month of February 2020 (2.40%) January (2.50%) as the temperature gone lower the infestation was recorded at minimum level. Overall average of Healthy fruits, Damaged fruits and Larva found inside damaged fruits were (44.65±3.91, 5.34±3.91 and 3.92±3.32) respectively. The results shown that the (10.69±7.82%) damage throughout year was done by Brinjal Fruit and Shoot borer (L. orbonalis G.) to Brinjal fruits.
