Bionomics of Peckia (Euboettcheria) anguilla and Peckia (Euboettcheria) collusor (Diptera: Sarcophagidae) in the laboratory

Abstract Flesh-flies are important mechanical vectors that cause myiasis in man and animals and they also play an important role in forensic entomology. Postmortem interval can be estimated using data available in the literature on the biology of the species. This study aims to elucidate the bionomics of these two species in order to provide preliminary data for medical, veterinary and forensic entomology analyses. We analyzed the larval stage durations (L1–L3), weight of the mature larvae (L3), L1-pupae stage duration, L3-pupae stage duration, pupal stage duration, L1–adult duration, adult emergence, atrophies and the viability of larvae and adults. The mean duration of the L1–adult of Peckia anguilla was 22.6 days and 21.8 days, in the first and second experiments. Mean lifespan for females and males was 75 and 69.6 days, respectively. The mean duration of the L1–adult of Peckia collusor was 25.9 days and 23.8 days, in the first and second experiments. Mean lifespan for females and males was 77.5 and 73.5 days, respectively. Although the two species presented similar results in relation to their post-embryonic development, P. collusor showed an adult lifespan longer, laying 1983 larvae throughout the experiment, while P. anguilla depositing 2298 larvae.
