Necrophagous phorid flies are common insects found on buried corpses, and their developmental data play a crucial role in estimating the post-burial interval (PBI). This study aimed to investigate the effects of soil type and moisture content on some life cycle parameters of two forensically important insects, (Loew, 1866) and (Bigot, 1857) (Diptera: Phoridae). Larval and pupal survival, development time, and larval body length of and were observed in three different soil types (loamy sand, sandy loam A, and sandy loam B) with six moisture contents (0%, 20%, 40%, 60%, 80%, and 100%).

Ptomascopus plagiatus (Ménétriés, 1854) is a forensically important silphid species. In this study, we report on the mitochondrial genome of . The complete mitochondrial genome of is 17556 bp and contains 22 transfer RNA genes, 13 protein-coding genes (PCGs), two ribosomal RNA genes, and a 2953 bp noncoding region.

The postburial interval (PBI) can be inferred by using necrophagous insects colonizing the buried corpse. In different seasons, the species composition and succession of necrophagous insects on swine carrion (0.5-0.

The mitochondrial genome is frequently used for species identification and phylogenetic studies. In this study, we first sequenced and annotated the complete mitochondrial genomes of two phorid species that are forensically important in buried or enclosed environments: Metopina sagittata (Liu) and Puliciphora borinquenensis (Wheeler). The complete mitochondrial genome sequences of M.

is one of the most important genera in the family Phoridae. This genus is mainly distributed in Palearctic region, and its species can be used to estimate the postmortem interval. In this study, we first present two mitochondrial genomes of common necrophagous species of this genus, (Meigen, 1830) and (Wiedemann, 1830).

and were two forensically important flies in relatively sealed environments. Their mitochondrial genomes were first sequenced, annotated, and phylogenetic analyses were performed with other 8 species of the Asehiza in this study. Maximum-likelihood phylogenetic tree revealed that Phoridae is closer to Platypezidae and Lonchopteridae within Diptera.

Dohrniphora cornuta (Bigot) is a forensically important phorid fly indoors and in burial environments. The determination of a minimum postmortem interval (PMImin) often relies on the determination of the age of the immatures. Although the larval development data of D.

In addition to causing myiasis in humans and animals, Megaselia scalaris (Loew) has been reported as a forensically important fly. The determination of a minimum postmortem interval (PMI) often relies on the determination of the age of the larvae and pupae. The pupal stage represents about 50% of the immature development time and the pupal age may therefore serve as an important tool in entomological minimum PMI estimation.

In addition to causing myiasis in humans, Megaselia spiracularis Schmitz has also been reported as a forensically important fly. The determination of a minimum post-mortem interval (PMI) often relies on the determination of the age of the larvae and pupae. The pupal stage represents about 50% of the immature development time and the pupal age may therefore serve as an important tool in entomological PMI estimation.

Morphology of all larval instars and puparium of Dohrniphora cornuta (Bigot), a most common phorid fly species indoors in China, is presented using scanning electron microscopy. The first instar larva was composed of 12 segments, each of segments 3-11 with six slender tubercles situated dorsally, dorsolaterally, and laterally in transverse row. These tubercles divided into two segments, of which the basal one was smooth, and the brush-shaped distal one was comprised of a cluster of fine spines.

Morphology of all larval instars and puparium of Diplonevra peregrina, a most common phorid fly species indoors in China, is presented using scanning electron microscopy. The first instar larva was composed of 12 segments, each of segments 3-11 with six spicate tubercles situated dorsally, dorsolaterally, and laterally in transverse row. The dorsal tubercles were much longer than the laterals and dorsolaterals.

Article Synopsis
  • The study focuses on the morphology of all larval stages and the puparium of the forensically significant fly, Megaselia spiracularis.
  • Key features observed include unique characteristics of each larval instar, such as the presence of spiracles and variations in the labium structure.
  • The research also compares M. spiracularis with another important fly species, M. scalaris, to highlight differences in their immature stages for forensic analysis.
