Use of a natural substance in the capture of fruit flies of the genus Anastrepha Schiner (Diptera: Tephritidae).
Standard glass McPhail traps using 2 lures for Anastrepha fruit flies were tested in an unsprayed non-commercial guava orchard in Turrúcares, Costa Rica, between August and September 1986. Traps were baited with either an aqueous solution of Torula dried yeast and sodium borate, or human urine. Two species of Anastrepha were captured: A. striata and A. obliqua. The urine was approximately 10 times more effective as a bait than Torula yeast.
