The viability was significantly lower at 10 °C and stabilised significantly from 20 °C upward, fitting to a quadratic equation. The mean embryonic development was 10.31, 8.44, 3.86, 2.18, and 2.04 days and was significantly less at 25 and 30 °C. The lower threshold temperature and the thermal constant were 7.4 °C and 44.2 d degree, respectively. Eggs were unable to complete development without a daily hydration regime. Adults fed with only honey yielded a lower total number of eggs compared to other diets (yeast + honey or inflorescences + honey). The offered diets did not alter the viability of the eggs or the longevity of adults of S. nigra. The results of this study indicated S. nigra egg development and viability was adequately maintained between 20-30 °C and with a daily hydration regime, and an artificial diet of yeast + honey was suitable for adults. This information will improve the efficacy of mass rearing techniques for the different stages of S. nigra.  aControle Biológico  aInseto  aPraga  aPredador  aFator abiótico  aFator biótico1 aDUARTE, M.1 aCALSAVARA, L.
