New techniques for Ceratitis capitata (Wiedemann, 1824) control are being studied and developed to replace traditional organophosphate pesticide applications. A mass trapping strategy offers promising medfly control within integrated pest management (IPM) programmes. Field assays were performed to study the efficacy of two mass trapping techniques based on PheroNorm® and Ceratrap® lures that were compared to a conventional approach to control the medfly in Tunisian apricot orchards. The results showed that both mass trapping techniques had a similar efficiency in reducing the C. capitata population. The degrees Brix in the fruits was a determinant issue since the initial apricot fruit damage was detected at 6.4%. At harvesting, the lowest fruit damage rate was recorded in the PheroNorm® (4.25%) and Ceratrap® (6.50%) treated orchards, compared with the conventional approach (10.75%). Therefore, the use of 50 PheroNorm® and Ceratrap® traps per ha density within an IPM approach may be very useful to control the C. capitata populations in apricot orchards.
