Resumen:
Two species of true fruit flies (taxonomic family Tephritidae) are considered pests of fruit and vegetable production
in Argentina: the cosmopolitan Mediterranean fruit fly (Ceratitis capitata Wiedemann) and the new world South
American fruit fly (Anastrepha fraterculus Wiedemann). The distribution of these two species in Argentina overlaps
north of the capital, Buenos Aires. Regarding the control of these two pests, the varied geographical fruit
producing regions in Argentina are in different fly control situations. One part is under a programme using the
sterile insect technique (SIT) for the eradication of C. capitata, because A. fraterculus is not present in this area. The
application of the SIT to control C. capitata north of the present line with the possibility of A. fraterculus occupying
the niche left vacant by C. capitata becomes a cause of much concern. Only initial steps have been taken to
investigate the genetics and biology of A. fraterculus. Consequently, only fragmentary information has been
recorded in the literature regarding the use of SIT to control this species. For these reasons, the research to
develop a SIT protocol to control A. fraterculus is greatly needed. In recent years, research groups have been
building a network in Argentina in order to address particular aspects of the development of the SIT for
Anastrepha fraterculus. The problems being addressed by these groups include improvement of artificial diets,
facilitation of insect mass rearing, radiation doses and conditions for insect sterilisation, basic knowledge
supporting the development of males-only strains, reduction of male maturation time to facilitate releases,
identification and isolation of chemical communication signals, and a good deal of population genetic studies. This
paper is the product of a concerted effort to gather all this knowledge scattered in numerous and often hard-toaccess
reports and papers and summarize their basic conclusions in a single publication.
