Dengue virus population genetics in Yogyakarta, Indonesia prior to city-wide Wolbachia deployment
Infect Genet Evol. 2022 May 26;102:105308. doi: 10.1016/j.meegid.2022.105308. Online ahead of print.ABSTRACTDengue has been endemic in Yogyakarta, Indonesia for decades. Here, we report the dengue epidemiology, entomology, and virology in Yogyakarta in 2016-2017, prior to the commencement of the Applying Wolbachia to Eliminate Dengue (AWED) randomized trial. Dengue epidemiological data were compiled and blood samples from dengue-suspected patients were tested for dengue virus (DENV). Ae. aegypti mosquito samples were caught from the field using BG-Sentinel traps and tested for the presence of DENV infection. Sequencing of ...

Forensic entomology in research and practice: an overview of forensic experts ’ perceptions and scientific output in Brazil
AbstractGiven the growing demands for standardization of procedures for collection, preservation, and identification of insect specimens, this study aimed to identify how forensic entomology is used in Brazil and the perceptions of professionals involved in this process. We conducted: (1) bibliometric survey of the scientific production of forensic specialists from 2001 to 2020; (2) questionnaire applied to forensic professionals to verify their perceptions about the use of entomological evidence in practice. An increase in publications on Forensic Entomology was noticed in the last 5  years, mainly in the South and North...

Comparison of DNA extraction techniques for the recovery of bovine DNA from fly larvae crops
J Forensic Sci. 2022 Feb 18. doi: 10.1111/1556-4029.15010. Online ahead of print.ABSTRACTForensic entomology aids investigations using insects and is primarily associated with the estimation of post-mortem interval (PMI). Studies have shown that human DNA can be recovered from the crops of fly larvae. While several factors regarding the recovery of human DNA from crops have been studied, DNA extraction methods have not been thoroughly assessed. Determining a method for optimal extraction could aid crime laboratories in implementing DNA extraction from larvae and streamlining future research. Bovine DNA was used as a substi...

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 ...

An examination of the intrapuparial development of Chrysomya albiceps (Wiedemann, 1819) (Calliphoridae: Diptera) at three different temperatures
In this study,Chrysomya albiceps (Wiedemann, 1819), which is a cosmopolitan species and one of the most rapidly attracted to carrion, was studied. The focus was the intrapuparial development periods of this species at varying temperatures (20, 25, and 30  °C), knowledge which is used in forensic entomology for the estimation of Post-mortem interval (PMI) and is a type of black box. At the specified temperatures, pupae were collected and puparia were dissected hourly; thus, developmental periods were determined, and minimum and maximum starting tim es of these periods were calculated. With this research, a total of 20 per...

It is all about the insects: a retrospective on 20  years of forensic entomology highlights the importance of insects in legal investigations
This study highlights the importance of insect evidence by evaluating 949 insect-associated cases, including 139 entomological reports, from 2001 to 2019 at the Institute of Legal Medicine Frankfurt/Germany. With a high number of cases in the summer months and a low number in the colder season, 78.5% of the bodies were found indoors, regardless of year or month. In more than 80% of the cases, where PMI information was available (n  = 704), the presumed PMI ranged from 1 to 21 days, a period during which entomological evidence can provide a day-specific estimate of PMImin. In cases where insects have been identified to...

MALDI-TOF mass spectrometry for the identification of freshwater snails from Senegal, including intermediate hosts of schistosomes
This study aims to evaluate MALDI-TOF MS profiling for the identification of both frozen and ethanol-stored snail species using protein extracts from different body parts. A total of 530 field specimens belonging to nine species (Biomphalaria pfeifferi,Bulinus forskalii,Bulinus senegalensis,Bulinus truncatus,Bulinus globosus,Bellamya unicolor,Cleopatra bulimoides,Lymnaea natalensis,Melanoides tuberculata) and 89 laboratory-reared specimens, including three species (Bi.pfeifferi,Bu.forskalii,Bu.truncatus) were used for this study. For frozen snails, the feet of 127 field and 74 laboratory-reared specimens were used to valid...
