	abstract = {Insect populations may differ in several life history traits, including behavioural ones such as sexual signalling. We tested whether male Mediterranean fruit fly (medlfy), Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), populations obtained from geographically isolated areas exhibit differences in quantitative and qualitative aspects of male sexual signalling. Male sexual signalling was studied in four medfly populations (originating from Brazil, Portugal, Kenya, and Greece) under identical laboratory conditions (25 degrees C, 60\% r.h., and L14:D10). The four populations had been reared for one generation in the laboratory. Sexual signalling was studied in the F(1) progeny that were fed one of two diets (yeast hydrolysate plus sugar or sugar only). On both diets, the four populations differed significantly in the progress of maturity (indicated by the average number of males exhibiting sexual signalling) and in the quantity of signalling after attaining maturity. Yeast availability significantly increased sexual signalling; however, it had a different impact on the quantity of signalling in the different populations. A bi-modal pattern of sexual signalling, with one peak at approximately 08:00-09:00 hours and the second at approximately 13:00-14:00 hours, was recorded for all populations and diets. However, quantitative differences among the populations within the {\textquoteright}sexually active{\textquoteright} period of the day resulted in significant differences in the daily pattern of sexual signalling. The significance of these findings for understanding adaptations of geographically isolated medfly populations to different ecosystems, as well as its practical importance for the application of the sterile insect technique against C. capitata, is discussed.},
