Standard quality control tests were carried out to evaluate the sexual performance of laboratory sterile Anastrepha obliqua males acclimated under field conditions. Laboratory sterile males were maintained in a mango orchard in wooden cages for 0, 2, 4, 6 and 8 days before competing with wild males for matings with wild females in sexual performance tests. Laboratory males were evaluated at 8 days of age while wild males were 15 days old. This study was conducted to confirm whether insects kept as close as possible to natural conditions, obtain an advantage in their sexual performance Quintero Fong et al.: Desempeño sexual de machos de A. obliqua aclimatados a campo with respect to males maintained under artificial conditions. The results of the study indicated that the mating proportion in the test was within SIT quality control standards and the relative sterility index values didn't show significant differences between the different treatments. In conclusion the data indicates that the pre-conditioning of A. obliqua males to field conditions doesn't give an advantage over non-conditioned males in sexual performance with wild females in field cages.
