New developmental data of Chrysomya megacephala (Diptera: Calliphoridae) in tropical temperatures and its implications in forensic entomology
Trop Biomed. 2023 Mar 1;40(1):1-6. doi: 10.47665/tb.40.1.003.ABSTRACTThe estimation of the postmortem interval (PMI) is an essential information in death investigations. It is necessary to know the developmental data of the most important necrophagous insect species in every geographical area. Chrysomya megacephala (Fabricius, 1794) (Diptera: Calliphoridae) is one of the most common species associated with human body decomposition, especially in the tropics, so a precise knowledge of its life cycle is crucial. However, despite its ubiquity, developmental data in a range of tropical temperatures is scarce. For this reason, ...

Morphology and identification of fly eggs: application in forensic entomology.
This study aims to investigate the morphology of forensically important fly eggs. Eggs of Chrysomya rufifacies, Chrysomya megacephala, Chrysomya pinguis, Chrysomya nigripes, Hypopygiopsis tumrasvini, Lucilia cuprina, Lucilia porphyrina and Musca domestica were examined using 1% potassium permanganate solution for 1 min. Morphometric analysis revealed that the mean length of Hy. tumrasvini (1.63 mm) and C. pinguis (1.65 mm) eggs was the longest, followed by that of L. porphyrina (1.45 mm), C. rufifacies (1.34 mm). The egg length, width of median area and darkness staining of hatching pleats were distinctive features. Four c...

Forensic entomology: Nuclear and mitochondrial markers for Diptera and Coleoptera identification
Abstract: Accurate identification of insect specimens is an essential step in forensic entomology. Cytochrome c oxidase subunit 1 (COI) is the most used locus for insects molecular identification. However, other studies were done using other genetic markers, as mitochondrial cytochrome b (CytB) and ribossomal second internal transcribed spacer (ITS2). Also, it was shown that COI has some limitations in this field. In this work these three markers (COI, CytB and ITS2) were used, with the aim to infer about its suitability for insects with forensic relevance identification.DNA was extracted from insects found in carcasses of...

Life history data on the fly parasitoids Aleochara nigra Kraatz and A. asiatica Kraatz (Coleoptera: Staphylinidae), and their potential application in forensic entomology
Abstract: Knowledge of the developmental time of the immature stages of necrophagous flies has been the main tool for estimating minimum post-mortem intervals (min PMIs) in forensic entomology. Many parasitic insects can alter the development of immature stages of flies and thus affect min PMI estimates. The larvae of most species of Aleochara rove beetles are ectoparasitoids of the pupae of cyclorrhapha flies. Among them, some species that parasitise necrophagous flies may have forensic importance. Two Taiwanese Aleochara species, A. nigra and A. asiatica, which visit carrion sites were studied herein. All five necrophago...

Entomology: Male mosquito boosts egg-making
Nature 503, 7474 (2013). doi:10.1038/503009d
Male mosquitos deliver more than sperm when they copulate with females: they also provide a hormone that spurs egg development.A team led by Flaminia Catteruccia at the Harvard School of Public Health in Boston, Massachusetts, studied the malaria-spreading mosquito Anopheles gambiae, focusing on

Ticks and associated diseases: a retrospective review
Abstract
This is a retrospective review of contributions to the understanding of ticks and associated diseases published in Medical and Veterinary Entomology since its first issue. It highlights the large and significant changes in the style and conduct of this field over the last 25 years. The selected papers refer to disease‐related categories of host immunity to ticks, population dynamics, pathogen transmission and tick control.

Molecular phylogenetic profiling of gut‐associated bacteria in larvae and adults of flesh flies
This study determined the diversity of gut microbiota in flesh flies, which will bolster the ability to assess microbiological risk associated with the presence of these flies. The present data thereby establish a platform for a much larger study.

Correlation of Molecular Expression with Diel Rhythm of Oviposition in Calliphora vicina (Robineau-Desvoidy) (Diptera: Calliphoridae) and Implications for Forensic Entomology.
This study explored the molecular mechanisms potentially underlying blow fly nocturnal oviposition. A behavioral study revealed that Calliphora vicina (Robineau-Desvoidy) (Diptera: Calliphoridae) possesses a diel rhythm of oviposition in light under 12:12 light/dark conditions. Reversal to 12:12 dark/light resulted in oviposition behavior changing to align with the adjusted regime in most females, but four of 59 experimental females lacked a diel rhythm of oviposition (were arrhythmic). Real-time PCR was used to monitor the molecular expression levels of known circadian genes per and tim in C. vicina to determine whether ...
