Abstract: Mate preference experiments were conducted between males
from two populations of the Mediterranean fruit fly, Ceratitis capitata, to
investigate the effect of body size on mating success. The results of the experiment
indicate that increased body size of males cannot be equated with mating
success. In the lek behavior phase, physical encounters between males for possession
of a preferred territory seem to favor a male with a larger body size.
However, males from one of the populations were twice as successful in mating
with females of either population than males from the other population despite
their significantly smaller body size. Thus, it appears that while size may possibly
be correlated with intrasexual selection and the establishment of a dominance
hierarchy within the lek, courtship performance is still the most important
criterion for mating success in the medfly.
