The flesh fly, , is a widely-used model for examining the physiology of insect diapause, development, stress tolerance, neurobiology, and host-parasitoid interactions. Flies in this taxon are implicated in myiasis (larval infection of vertebrates) and feed on carrion, aspects that are important in forensic studies. Here we present the genome of , along with developmental- and reproduction-based RNA-Seq analyses. We predict 15,768 protein coding genes, identify orthology in relation to closely related flies, and establish sex and developmental-specific gene sets based on our RNA-Seq analyses. Genomic sequences, predicted genes, and sequencing data sets have been deposited at the National Center for Biotechnology Information. Our results provide groundwork for genomic studies that will expand the flesh fly's utility as a model system.

Microplastics in livestock manure pose a growing environmental concern, which could possibly enhance the bioavailability of heavy metals to flesh fly, such as the Boettcherisca peregrina, a candidate biological agent for manure valorization. In this study, the impact of polystyrene microplastics (PS MPs, 0-0.1 mg/g) on larval growth, heavy metal accumulation and gut microbiota in B.

The pupal stage in necrophagous flies represents the longest and least morphologically distinct phase of development, posing a persistent challenge for accurately estimating postmortem intervals (PMI) in forensic investigations. Here, we present a novel molecular approach to pupal age estimation in , a forensically important species, by profiling microRNA (miRNA) expression dynamics. High-throughput sequencing across early, mid, and late pupal stages identified 191 known miRNAs, of which nine exhibited distinct monotonic temporal trends.

Sarcosaprophagous insects play a pivotal role in forensic entomology, particularly in estimation of the postmortem interval (PMI). Among them, Sarcophaga princeps Wiedemann, 1830 (Diptera: Sarcophagidae), demonstrates distinct ecological traits such as larviposition and the ability to colonize buried remains. Even so, it has been hard to learn more about its molecular biology since a high-quality genome assembly is missing.

This study investigates arthropod assemblage in cowpea, hemp, and watermelon grown both as monocrops and intercrops using three sampling techniques: direct visual counts, sticky cards, and pan traps. A total of 31,774 arthropods were collected, spanning two classes [Arachnida (0.07%) and Insecta (99.

Flesh flies (Sarcophagidae), along with blow flies, are among the first colonizers of vertebrate cadavers, including human corpses. Their early colonization and rapid development frequently result in the collection of flesh fly larvae as evidence during crime scene investigations or autopsies. Despite their regular occurrence and confirmed forensic importance, the species-level identification of sarcophagid larvae remains challenging.
