Estimating the intra-puparial period of Hydrotaea spinigera (Stein,1910) (Diptera: Muscidae) with morphological and gene expression changes
This study provides an important basis for forensic entomology to use morphological and differential gene expression for estimating the age of H. spinigera during the intra-puparial period. Moreover, the combination of the two methods can produce a more accurate minimum postmortem interval (PMImin) estimate compared to when each method is used separately.PMID:36963598 | DOI:10.1016/j.actatropica.2023.106910

Near infrared spectroscopy (NIRS) coupled with chemometric methods to identify and estimate taxonomic relationships of flies with forensic potential (Diptera: Calliphoridae and Sarcophagidae)
This study shows that NIRS is efficient to identify flies' taxonomic properties, such as family and genera, providing quick evidence for the tested species identity.PMID:36041495 | DOI:10.1016/j.actatropica.2022.106672

Coexistence and intraguild competition of Chrysomya albiceps and Lucilia sericata larvae: case reports and experimental studies applied to forensic entomology
Acta Trop. 2021 Nov 19:106233. doi: 10.1016/j.actatropica.2021.106233. Online ahead of print.ABSTRACTThe larval development of Chrysomya albiceps and Lucilia sericata is a well-known and valuable tool for estimating the postmortem interval (PMI). The third instar larvae of Ch. albiceps are facultative predators of the larvae of other necrophagous dipterans, and this behaviour is undoubtedly an important factor to consider. Both species are found together during human autopsies in Spain and other parts of Europe, where they cohabit, so a precise knowledge of their larval coexistence data is essential. The aim of this study ...

Morphology of immature blow fly Hypopygiopsis infumata (Bigot) (Diptera: Calliphoridae), a potential species of forensic importance.
This study highlighted the main features of cephaloskeleton of H. infumata larvae as observed under LM. Particular attention is given to oral sclerite and rough surface of dorsal cornua which can distinguish between H. infumata and H. tumrasvini. PMID: 30194921 [PubMed - as supplied by publisher]

Artificial blood feeders for mosquito and ticks-Where from, where to?
Abstract Mosquito and tick feeding activity represent a key threat for humans, livestock, pets and wildlife worldwide. Rearing these vectors in laboratory conditions is extremely important to investigate basic facets of their biology, vector competence, new control strategies as well as mechanisms of pesticide resistance. However, the use of animals or humans to provide blood for hematophagous arthropods feeding pose a strict limit to these researches, due to the accidental transmission of diseases, ethical problems concerning animal welfare, as well as the expensive and time-consuming animals rearing. The use of ...

Scanning electron microscopic studies on antenna of Hemipyrellia ligurriens (Wiedemann, 1830) (Diptera: Calliphoridae) - a blow fly species of forensic importance.
Abstract Blow flies (Diptera: Calliphoridae) are one of the foremost organisms amongst forensic insects to colonize corpses shortly after death, thus are of immense importance in the domain of forensic entomology. The blow fly Hemipyrellia ligurriens (Wiedemann, 1830) (Diptera: Calliphoridae) is considered as a forensically important fly species globally and is also known for its medical and veterinary importance. In the present study, we report for the first time scanning electron microscopic studies on the morphology of sensilla of antenna of adult male and female of H. ligurriens is with profound importance in ...

Ultrastructure of immature stages of the black dump fly, Ophyra aenescens (Wiedemann, 1830) (Diptera: Muscidae: Azeliinae).
In conclusion, the SEM technique used and the results obtained are helpful to describe and differentiate the immature stages of O. aenesces and consequently support forensic and medical entomology. PMID: 26943996 [PubMed - as supplied by publisher]

How heterogeneous is the involvement of ABC transporters against insecticides?
Abstract Understanding the molecular mechanisms underlying cellular defense against xenobiotic compounds is a main research issue in medical and veterinary entomology, as insecticide/acaricide resistance is a major threat in the control of arthropods. ABC transporters are recognized as a component of the detoxifying mechanism in arthropods. We investigated the possible involvement of ABC transporters in defense to the organophosphate insecticide temephos in the malarial vector Anopheles stephensi. We performed bioassays on larvae of An. stephensi, using insecticide alone and in combination with ABC-transporter inh...

Ultrastructural studies of some character of Diptera (Muscidae) of forensically importance.
Abstract Insects are important in the decomposition of cadavers. In the field of forensic entomology, the taxonomic identification is essential to proceed to any procedure. The use of these insects in medico criminal investigation is the object of forensic entomological studies; the flies are generally attracted to cadavers and one of the most important contributions is to estimate the postmortem interval. The scanning electron microscopy, which allows rapid and accurate identification of character could be used to help identify different species of forensics flies, has been highlighted as it allows better visuali...

Social sustainability of Mesocyclops biological control for dengue in South Vietnam.
Abstract Copepod Mesocyclops as biological control agents for dengue was previously proven to be effective and sustainable in the Northern and Central provinces of Vietnam. We aim to study social sustainability of Mesocyclops intervention in south Vietnam. Both quantitative and qualitative approaches were used. An entomological survey was carried out in 100 random households of Chanh An commune, Vinh Long Province. Aedes larval indices and Mesocyclops prevalence were compared with historical pre- and post-intervention values. In the same commune, using purposeful sampling, sixteen semi-structured interviews (1 vil...
