abstract
The oriental fruit fly, Bactrocera dorsalis Hendel (Diptera: Tephritidae) is an important pest of mango which limits the export of mango from one country to another. The experiments was conducted at Regional Fruit Research Station, Vengurla (Dr. B. S. Konkan Krishi Vidyapeeth, Dapoli, M. S.) during 2002 to 2017 by installing ‘Rakshak’ fruit fly traps in mango orchards @ 4 traps/ha for mass trapping of fruit flies. The results revealed that there was fruit fly catch in ‘Rakshak’ trap throughout the year, however, the peak incidence period was May-June. During the initial years (2002 to 2005) the fruit fly catch was very high (>1000/trap/week), which further declined continuously from 2006 onwards to 242.25/trap/week during 2017 due to the continuous mass trapping.
