Survival, longevity, and reproductive aspects of Diptera are related to biotic and abiotic factors, as well as to their interaction. The aim of this study was to determine the influence of storage of adult Musca domestica in low temperatures (5°C, 10°C) by bionomic aspects (survival, longevity, number, and viability medium eggs.females-1) from pre-established colonies (temperature 25°C+2°C; UR70 +10%; 12 h photoperiod). 15 couples/repeat x 3 were randomly selected and housed in chambers at temperatures of 5°C, 10°C, and 25°C+2°C (control) (Factor A). The flies were removed from the chambers at 7, 14, 21, 28, 35, and 42 days (Factor B), when the survivors were counted and placed in cages at 25°C+2°C, until the death of the last fly. The results were statically tested (Anova, Tukey 5%). The use of low temperatures for storage of adults was a strategy that interfered in bionomic aspects of the insects. The use of low temperatures interfered in adult survival, longevity, number medium/eggs.females-1, and viability when compared to control. Expose adults in B.O.D., temperature 5 and 10°C, for seven days allows the overall survival, survival of males and females, longevity, larger number medium eggs.females-1, and egg viability.
