The combination of a yellow color sticky rectangle with an ammonium acetate slow-release dispenser (YAA) was compared to a yellow sticky rectangle (Y) and to a McPhail glass trap with BuminalTM(MB), EntomozylTM(ME), or ammonium sulfate (MAS) odor lure in a 2% water solution, from the beginning of August till December in an olive grove. When total olive fruit fly, Dacus oleae (Gmelin) (Diptera: Tephritidae), captures were compared, no large differences were detected among YAA, MB and ME traps, while Y and MAS ones were found much inferior. When expressed as a ratio to YAA, total captures were: 1 (YAA), 0.95 (MB), 0.70 (ME), 0.33 (Y) and 0.08 (MAS). In the fall (high population density), both yellow traps showed very high catches, while McPhail odor traps had comparatively reduced effectiveness, apparently due to cool humid weather. The opposite was true in August-September (hot dry weather, low population density). McPhail traps were serviced every 5 days (summer) or 7 days (fall), while YAA and Y traps were replaced by new ones only once, at the beginning of October. The ammonium acetate dispenser could last much longer but traps had been covered by insects and debris.
