[Bionomical aspects of the Squamatoides triviattus (Diptera, Sarcophagidae) under laboratory conditions].
Experiments with Squamatoides trivitattus were carried out in two different controlled temperatures (16 +/- 1 degree C/50-60% RH and 27 +/- 1 degree C/70-80% RH). The viability of larvae and pupae at 27 degrees C was 89.82% and 92.75% respectively. Larvae did not develop at 16 degrees C. Larval development lasted for 20 +/- 4 hr, 16 +/- 8 hr and 60 +/- 7 hr for the first, second and third instars, respectively, completing a total of 96 +/- 6 hr. The mean pupal period lasted for 15.7 +/- 1.6 days. In longevity tables for the adults, life-expectancy for 50% of the colony submitted to 16 degrees C was of 1.78 weeks for males and 2.42 for females. At 27 degrees C a life-expectancy of 1.15 weeks for males and 0.78 week for females was recorded. The average life-spans for males and females at 16 degrees C were 3.5 +/- 2.0 and 3.8 +/- 2.6 weeks, respectively, and 1.9 +/- 1.2 weeks for both sexes. At 27 degrees C, the longevity recorded was of 2.1 +/- 1.3 weeks for males and 1.7 +/- 1.1 week for females.
