Studies were made on attraction of female fruit flies to different protein food baits in farmers' commercial guava and mango orchards during 2005-06 near Dharwad. Food bait containing proteinex and 5 per cent ammonium acetate attracted significantly more Bactrocera correcta (5.17 fruit flies/trap/week), B. dorsalis (9.42 fruit flies/trap/week), B. cucurbitae (2.25 fruit flies/trap/week) and total fruit flies (16.84 fruit flies/trap/week) in guava. While in mango, fruit fly diet and mango pulp combined with 5 per cent ammonium acetate were attractive to B. dorsalis (7.63 and 4.63 fruit flies/trap/week, respectively), B. cucurbitae (3.00 and 4.25 fruit flies/trap/week, respectively) and total fruit flies (10.63 and 8.88 total fruit flies/trap/week, respectively). Food baits containing guava pulp with ammonium acetate in guava (5.59 total fruit flies/trap/week) and casein with ammonium acetate, mango pulp and proteinex with 5 per cent acetic acid ( 3.18, 4.63 and 3.51 total fruit flies/trap/week, respectively) were the next best treatments in mango.
