Abstract

Field experiments were conducted in a mango orchard in Croix-des-Bouquets, Haiti, to compare the effectiveness of 2 inexpensive artisanal trap types and the standard McPhail trap (Great Lakes IPM, Inc., Vestaburg, Michigan) for capturing fruit flies Anastrepha obliqua (Macquart) and Anastrepha suspensa (Loew) (Diptera: Tephitidae) and to ascertain the optimal trap density for mass trapping these flies. Two artisanal trap designs were constructed from inexpensive plastic soda bottles. In 1 design the plastic bottle was clear, and in the other design the plastic bottle had the bottom 20% painted yellow. These 2 traps and 1 McPhail trap were placed in replicated groups in the mango orchard. The mean number of flies captured in clear artisanal traps (13 flies) was similar to that captured in the McPhail trap (16 flies), but the cost of 20 artisanal traps (US70) was less than 1 third of the cost of 20 McPhail traps (US220). A 2nd field trial was implemented to compare the number of flies captured in 24 McPhail traps per ha (236 flies) to the number of flies captured in 36 clear artisanal traps per ha (239 flies). The number of flies captured did not differ significantly between the 2 trap type densities. A 3rd experiment evaluated the optimal trap density for mass trapping fruit flies. Our data indicated that a density of 25 traps per ha is adequate to protect a mango orchard through the maturation phase of the mango season. These results indicated that cost-effective artisanal traps can replace the McPhail trap for mass trapping fruit flies in Haiti.
