RESUMO
Longevity is an important characteristic of life history of species which is influenced by environment, genetic constituition and sexual activity. Three sexual activity regimes were investigated in three geographical lineages in Megaselia scalaris Loew, 1866 that have been maintened in the laboratory at 25ºC. It was observed that virgin flies are more longevous than others, females more than males, and a sex-lineage interaction underlying this pattern variation. It was observed an inverse relation between the environmental temperature of the lineages's locality and longevity.
