Abstract
The present investigations on “Seasonal incidence, biology and management of peach fruit fly under low hills conditions of Himachal Pradesh” were conducted during 2022-2023. The investigation has provided valuable insights into the fruit fly population spanning from April 2022 to May 2023. It was observed that the highest population of fruit flies occurred in the month of May 2023, followed by August 2022 and September 2022. The biological investigation revealed that the developmental period from immaturity to adulthood in females spanned from 18-30 days, with an average duration of 26.3 ± 1.49 days. For males, this period ranged from 15-24 days, with an average of 20.8 ± 0.98 days. Among the various Male Annihilation Techniques assessed for controlling fruit flies, the combination of methyl eugenol (4ml), ethanol (6ml), and malathion (1ml), using a septum measuring 8 cm × 2 cm × 1.8 cm, stood out as significantly more effective than other treatments. Among different baits experimented to combat fruit flies, the combination of casein, sugar, banana pulp (1:1:1) and 5% ammonium acetate proved significantly superior. In the evaluation of numerous insecticides and botanical treatments for their effectiveness, it was determined that chlorantraniliprole (0.005%), spinosad (0.004%) and cyantraniliprole (0.002%), exhibited notable efficacy in the control and management of fruit flies on peach trees.
