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

[摘要] 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.
