The fruit culture consolidates every year as an important activity for the economic development of Brazil, and the fig (var. “Figo-roxo de Valinhos”) (Ficus carica L.) is among the twenty main fruits exported by the country. However, recently, this culture has been affected by a plague originated from Africa, Zaprionus indianus Gupta, 1970. This insect has caused huge losses in production volumes, because the female lays eggs in the fruit and then it is used as a substrate for the development of immatures and thus it becomes inedible. However, the control of this drosophilid is not yet largely implemented due to a lack of basic information about the biology of this species, such as those involving development time and competition under different larval densities. Therefore, this study aimed to analyze the development of Z. indianus and some bionomic characters (viability, pupal weight, adult weight, wing size, sex ratio and fecundity) in order to relate the effect of different densities (50, 100 and 200) and different diets (Control Diet (C) and Diet with twice yeast (2L)). The results show that both the density and diet caused significant variations in the attributes tested. Moreover, the critical weight for both diets was tested, and the immatures that developed in Diet 2L achieved the critical weight in shorter time. However, for more precise results, further testing is necessary.
