Oxysarcodexia amorosa (Schiner, 1868)

The larval viability of O. amorosa was 76% ( Table 3). The larval stage had a mean duration of 3.51 ± 0.64 days, with a minimum of 3 and a maximum of 6 days ( Table 3). L3 abandoned the diet and started pupation with a mean weight of 28.28 ± 3.38 mg, with a minimum of 14 mg and a maximum of 39 mg. The mean weight of L3 that originated adult males was 28.83 ± 2.53 mg, ranging from 22 to 37 mg, and the mean weight of L3 that originated adult females was 28.28 ± 3.33 mg, ranging from 14 to 33 mg ( Table 4). No significant differences between the larval weight of O. amorosa males and females were observed ( Table 4). The pupal viability was 88.15% ( Table 3). The mean duration of the pupal stage was 10.14 ± 0.63 days, ranging from 9 to 11 days ( Table 3). The percentage of males and females was, respectively, 53% and 47% and the sex ratio was 0.47. The duration of the L1 to adult ranged from 12 to 16 days, showing a mean duration of 13.60 ± 0.69 days and a viability of 67% ( Table 3). The mean lifespan of O. amorosa was 83.66 ± 15.94 days for females and 84.00 ± 19.97 days for males ( Fig. 3 ). The number of larvae deposited per female of O. amorosa ranged from 0.33 to 12.07 (on Day 29) ( Fig. 4 ). At the end of the experiment 4781 larvae had been deposited on the putrefied ground beef, between the 12th and 85th day of the experiment.
