Female mosquitoes of the genus Sabethes Robineau-Desvoidy, 1827 are implicated in transmission several arboviruses, including yellow fever virus. Here, we present an illustrated species identification key for females recorded Brazil, except Sa. nitidus Theobald, 1901 and harbachi Nascimento-Pereira, Guimares, Loureno-de-Oliveira & Motta, 2021 as only males these known. The is available dichotomous interactive formats. An updated list Brazil new occurrence records states country provided....

Chrysomya megacephala represents a major threat to public health. It is mechanical vector of various pathogens, such as viruses, bacteria, and protozoan cysts, while their larvae may cause myiasis. The alternative synthetic insecticides, which are harmful the environment man`s health, use natural insecticides that safe for both. Plant derivatives have gained prominence in this field, but little known about how diluents used formulations can influence insecticidal activity, physiology...

The postmortem interval is related to the age of immature species flies found on corpses and can be estimated using data available in literature biology species. flesh fly Ravinia belforti a carrier enteric pathogens that affect human animal health as well being forensic importance. As morphology many Sarcophagidae unknown, these forms must collected characterized after emergence adult male. Here we describe analyze morphological characteristics larvae stages L1, L2, L3 puparium R. by...

This study aims to elucidate the bionomy of Peckia (Sarcodexia) lambens and Oxysarcodexia amorosa provide data for medical, veterinary forensic entomology analyses. We analyzed larval stage duration (L1–L3), weight mature larvae (L3), pupal duration, L1–adult adult emergence viability adults both species. Larval P. (S.) was 82% mean 3.51 ± 0.99 days.

Abstract Flesh-flies are important mechanical vectors that cause myiasis in man and animals they also play an role forensic entomology. Postmortem interval can be estimated using data available the literature on biology of species. This study aims to elucidate bionomics these two species order provide preliminary for medical, veterinary entomology analyses. We analyzed larval stage durations (L1–L3), weight mature larvae (L3), L1-pupae duration, L3-pupae pupal L1–adult adult emergence,...
