Aspectos bionômicos de Squamatoides trivittatus (Diptera, Sarcophagidae) sob condições de laboratório

Abstract

Bionomical aspects of de

Bionomy of two flies of sanitary and forensic importance: Peckia (Sarcodexia) lambens (Wiedemann) and Oxysarcodexia amorosa (Schiner) (Diptera, Sarcophagidae)

“…The results of the larval stage duration for P. (S.) lambens and O. amorosa were similar those by Ferraz (1995) with Peckia (Peckia) chrysostoma (Wiedemann, 1830), where the duration of the larval stage was 3.91 ± 0.08 days at 25.9 • C. However, the results were unlike those obtained by Salviano et al (1996) for P. (S.) trivittata, where the mean duration was 4.2 days at 27 • C. Nassu et al (2014) studied the developmental rate of two immature flesh flies, and obtained 4.6 days for the mean duration of the larval stage of Sarcophaga (Liopygia) ruficornis (Fabricius, 1794) at 25 • C and 6.5 days for Microcerella halli (Engel, 1931) at 25 • C. At 30 • C, the mean duration of the larval stage of these species was very similar to what was observed at 25 • C (4.5 and 6 days, respectively). Therefore, S. (L.) ruficornis and M. halli show duration of larval stage different from O. amorosa and P. (S.) lambens, regardless of the temperature is lower or higher.…”

“…The percentage of males and females obtained by Salviano et al (1996) for P. (S.) trivittata was 54.36% for male and 45.64% for female. This result is very similar to the sex ratio for P. (S.) lambens and O. amorosa.…”

“…Therefore, S. (L.) ruficornis and M. halli show duration of larval stage different from O. amorosa and P. (S.) lambens, regardless of the temperature is lower or higher. Salviano et al (1996) suggested discriminate male and female by L3 larvae weight. The mean weight of P. (S.) trivittata was 257 ± 33 mg for L3 males and 238 ± 34 mg for L3 females.…”

“…However, for the L3 weight of P. value was observed to discriminate the males from the females. Larvae of P. (S.) lambens that weighed less than 22 mg reached the pupal stage, but they did not emerge as adults; this may be considered a threshold weight for adult development ( Ferraz (1995) obtained a pupal viability of 96.9 ± 2.5% for P. (P.) chrysostoma at 25.9 • C, while Salviano et al (1996) (Nishida, 1984;Jirón and Bolaños, 1986). This duration is considerably greater than that of the pupal stage of P. (S.) lambens (6-12 days), which shows that some species of Sarcophagidae may have a more rapid adult emergence.…”

“…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. Salviano et al (1996) obtained a value of larval viability of 89.82% at 27 • C, for P. (S.) trivittata (Curran, 1927) (as Squamatoides trivittatus) and Madubunyl (1986) obtained a value of larval viability of 80.69% at 23-28 • C for Sarcophaga (Bercaea) africa (Wiedemann, 1824) (as Sarcophaga haemorrhoidalis). These results were similar to P. (S.) lambens.…”
