Resumo: Tuta absoluta eggs were evaluated as host for Trichogramma evanescens with the aim of using indigenous species for biological control of the South American tomato moth. After being proved that T. evanescens could parasitize and achieve the complete development inside this host, parasitism rate, proportion of eggs within the parasitoid that reach the adult stage and viability of development rate, at three different temperatures (22.0ºC, 24.0ºC and 25.5ºC) were evaluated. Parasitism rate and the proportion of eggs with emerging hole were calculated as number of parasitized eggs and number of eggs with emerging holes, respectively, by the number of viable eggs. The viability of parasitoid development until adult stage was calculated as number of eggs with emerging hole/number of parasitized eggs. T. evanescens parasitized T. absoluta eggs at all the studied temperatures. Parasitism rate and proportion of eggs with emerging holes were higher at 22.0ºC; viability of development till adult was higher at 24.0ºC.
