Longevity of adults of Peckia chrysostoma and Adiscochaeta ingens (Diptera: Sarcophagidae) reared with and without protein

With access to a proteic source in the diet the mean longevity and lethal time (MLT) of Peckia chrysostoma was 52.6 ± 5.5 and 30.3 ± 5.9 days, respectively. With an isolated protein source, the mean longevity was 49.1 ± 2.6 days and the MLT was 28.5 ± 0.8 days. Without a proteic source the mean longevity and the MLT lowered to 37.4 ± 4.0 and 18.1 ± 1.3 days, respectively. For Adiscochaeta ingens the mean longevity with access to a proteic source in the diet was 29.0 ± 6.0 days and the MLT was 16.7 ± 2.7 days. The figures with an isolated proteic source were 26.9 ± 4.8 and 14.9 ± 2.0 days, and without a proteic source were 24.7 ± 4.2 and 13.3 ± 1.4 days, respectively. These results show that in P. chrysostoma the longevity is higher than in A. ingens and that the access to the proteic source increase the longevity in both species.
