Abstract
A greenhouse testing system for fruit fly traps and lures was examined. The system allowed comparison of traps and lures for Anastrepha suspensa Loew within 14 days. Because the actual fly population is known each day of testing, the efficiency of the trap/lure can be estimated. The standard, glass McPhail trap baited with yeast pellets had an average daily efficiency of 36.7 ± 21.8%. Greenhouse data for the standard, glass McPhail trap for female bias, lack of sugar attractiveness and general efficiency were comparable to previous field results. No trap/lure combination trapped all flies. The greenhouse fly population decreased about 50% per day regardless of trap numbers or lures. Costs for one greenhouse testing cycle were estimated as $2,400 compared to $52,500 for a similar test in the field.
