DE ARRIBA, Andrea V.  y  COSTAMAGNA, Sixto R.. Post-embrionary development of Microcerella acrydiorum (Diptera: Sarcophagidae) under laboratory conditions. Rev. Soc. Entomol. Argent. [online]. 2006, vol.65, n.1-2, pp.55-61. ISSN 0373-5680.

We studied Microcerella acrydiorum (Weyenbergh) postembrionary development and we determined the following biological parameters: time of larval and pupal development, prelarviposition period, survival, and sexual rate; under controlled conditions (average temperature: 27.50 ± 2.60 ° C, average relative humidity: 36.47 ± 8.10% and artificial photoperiod: 14 hours light). The average time of larval development was of 3.78 ± 0.81 days, the average time of pupal development was of 8.63 ± 1.45 days, the prelarviposition period was of 18.25 ± 4.06 days, and the total cycle was of 30.66 days. Survival probability to the adult stage was of 75.80%. At least, 98.73% of the larvae reached the pupal stage; 85.81% of the latter fully completed metamorphosis, and once transformed into adults, they abandoned the puparium. Only 89.47% of adults did emerge to the surface. Pupal stage was the most susceptible concentrating approximately 58% of the deaths. Sex rate was very similar to the expected relation, i.e. 1:1 (p>0,15).
