Zaprionus indianus Gupta(Diptera, Drosophilidae) is an invasive pest species that has colonized theAmerican continent in the last 20 years. This species is polyphagous invasive species that togetherwith Drosophila melanogasterMeigen (Diptera, Drosophilidae) y D.simulans Sturtevant (Diptera, Drosophilidae) utilized a wide variety of fruits as breeding andfeeding resources. In the present study we quantified the relativeabundance of these species in adult and emerged samples collected from varioushosts (commercial fruits) in different populations distributed in northernArgentina. Our results revealed that Z. indianus exhibitedthe highest emergency record from guava and mango resources. In addition, therelative abundance between Drosophila and Z. indianus species variedbetween samples (adults and emerged) in the populations analyzed. This resultrevealed a differential use of resources and/or interspecific competition.
