Fruit flies belonging to family Tephritidae have in the recent past caused serious economic losses in tomato crop in mid and low hills of Himachal Pradesh. The avoidable yield losses and fruit damage by fruit flies in tomato were 17.89 and 9.1 percent, respectively. Bactrocera (Zeugodacus) scutellaris was the most predominant species followed by B. (Z.) tau and B. (Z.) cucurbitae in Mandi district of Himachal Pradesh. In the on farm trials male annihilation using mixed lure traps+ bait application was found most effective treatment for fruit fly management recording highest net returns and BC ratio of Rs. 149480/ ha and 4.32, respectively. Pooled data of front line demonstrations for five crop seasons from 2014-2018 for area wide integrated management of fruit flies were found effective in reducing the fruit damage due to fruit flies by 19.98 percent and increased yield by 19.35 percent. The technology and extension gap of demonstrated technology was 106.98q/ha and 31.65q/ha, respectively which require further address by suitable research and extension techniques. Demonstrated technology not only convinced the farmers for using trapping as an integral component of fruit fly IPM but also resulted in reducing the pesticide load as evident by sale of more than 50000 fruit fly traps and reduction in pesticidal applications.
