The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), is one of the most destructive fruit pests in the world, especially on
economical crops such as oranges. This study was carried out to evaluate the attraction efficiency of food-olfactory combined with food
attractants as well as the mass trapping technique on the reduction rate of C. capitata adults population. The food attractant Buminal (Bu) and
two olfactory compounds, diammonium phosphate (DAP) and ammonium acetate (AA) were used and compared to a partial spray in a citrus
orchard located in El-Gharbia governorate, Egypt. The results obtained showed that all tested mixtures had more attraction efficiency than the
other tested compounds alone. The mixture solution of Bu + DAP + AA at a ratio of 1:1:1 significantly attracted the highest average numbers
of C. capitata adults throughout the four weeks of investigation compared to other tested compounds. The tested mixture and DAP, Bu, and
AA alone trapped 8.64, 1.83, 1.78, and 0.61 flies per trap per day, respectively. Thus, this mixture was evaluated as a mass trapping technique
comparable to a partial spray. The partial spray treatment was significantly different compared to mass trapping, showing a reduction of 56.71
and 24.60%, respectively.
Key words: Ceratitis capitata, mass trapping, partial spray, food attractant, ammonium compounds.
