The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), is an exotic pest of economic importance in several parts of the world. Systems for monitoring this pest employ mainly trimedlure (TML), a parapheromone specifically for males. Understanding the performance of these attractants under different conditions should contribute to better design trapping networks, better field data interpretation, and a more efficient use of the products. In this study, the release rate of TML was determined at 15, 25, and 35 °C, through plug weight loss over 80 d in a bioclimatic chamber. The attraction of TML of different ages was determined in field cage tests located in a mango orchard. Our results showed a direct relationship between TML release rate and temperature. Attraction was dependent on release rate. We found that TML storage for >4 yr at 27 °C affected the quantity of the active ingredient available for release. The results are discussed in terms of the effects of these conditions on the effi- ciency of trapping networks used for the detection of this pest and quality assurance for detection programs.
