Última Fitness components of a recently-established population of Zaprionus indianus (Diptera, Drosophilidae) in Brazil Iheringia, Sér. Zool. Setta,Nathalia de; Carareto,Cláudia M. A.. This study aimed to evaluate fitness components of Zaprionus indianus Gupta, 1970, a species recently introduced in Brazil and currently in process of colonization. Longevity, productivity, developmental speed and viability of flies sampled from a population from Mirassol (state of São Paulo, Brazil) were evaluated. Longevity was higher than that of some Indian populations and productivity was similar or higher than in other Drosophilidae. Time of development, one of the main fitness components for competition, was very similar to the values scored in Drosophila sturtevanti Duda, 1927, a species that occurs in high frequencies in the same area as Z. indianus. These data might contribute further for understanding the colonization success of this newcomer...

This study analyzes the pre-adult interactions of Zaprionus indianus, a recently-introduced species in Brazil, with two others Drosophilidae under laboratory conditions. The effects of larval residues on the viability and on the developmental time of Z. indianus, Drosophila simulans and D. sturtevanti were used to evaluate pre-adult competitive interactions, conditioning the culture medium with larval residues. Pre-adult interactions between Z. indianus, D. sturtevanti and D. simulans may affect their relative abundance over time, since the viability of Z. indianus was negatively affected by residues of D. sturtevanti, and its residues reduced the viability of D. simulans and the developmental time of both D. simulans and D. sturtevanti.
