DARAWAN WANACHIWANAWIN. 174 pp. The propose of this research was the comparison of the estimation of the postmortem interval between insect larvae from corpses and the opinions of the forensic medicinal doctor. The insect larval samples were collected from 35 corpses which sent to the Institute of Forensic Medicine Police General Hospital, Royal Thai Police, for medicocriminal investigations during March – November, 2008. The experimental breeding was carried out in ox liver for studying the life cycle interval for metamorphosis and identification of the insect. The results from this study indicated that the postmortem interval established by identifying the life-cycle stages of the insect which could related with the opinions of the forensic medicinal doctor at the high correlation level (r = 0.902). From the study of the larval morphology and development, it was found that there were 1 orders, 3 families, 4 genera and 6 species of the insects.The most frequency number of the insect and useful for estimation of the postmortem interval was blow fly; Chrysomya bezziana, C. rufifacies, C. megacephala and Lucilia cuprina. The flesh fly; Parasarcophaga ruficornis and The house fly; Synthesiomyia nudiseta. This information was potentially useful for estimating the postmortem interval of a corpse in forensic investigation by identifying the life-cycle stages of these insect species.

    Systematic Entomology (2020), DOI: 10.1111/syen.12443 Protein-encoding ultraconserved elements provide a new phylogenomic perspective of Oestroidea flies (Diptera: Calyptratae) ELIANA BUENAVENTURA1,2 , MICHAEL W. LLOYD2,3,JUAN MANUEL PERILLALÓPEZ4, VANESSA L. GONZÁLEZ2, ARIANNA THOMAS-CABIANCA5 andTORSTEN DIKOW2 1Museum für Naturkunde, Leibniz Institute for Evolution and Biodiversity Science, Berlin, Germany, 2National Museum of Natural History, Smithsonian Institution, Washington, DC, U.S.A., 3The Jackson Laboratory, Bar Harbor, ME, U.S.A., 4Department of Biological Sciences, Wright State University, Dayton, OH, U.S.A. and 5Department of Environmental Science and Natural Resources, University of Alicante, Alicante, Spain Abstract. The diverse superfamily Oestroidea with more than 15 000 known species includes among others blow flies, flesh flies, bot flies and the diverse tachinid flies. Oestroidea exhibit strikingly divergent morphological and ecological traits, but even with a variety of data sources and inferences there is no consensus on the relationships among major Oestroidea lineages. Phylogenomic inferences derived from targeted enrichment of ultraconserved elements or UCEs have emerged as a promising method for resolving difficult phylogenetic problems at varying timescales. To reconstruct phylogenetic relationships among families of Oestroidea, we obtained UCE loci exclusively derived from the transcribed portion of the genome, making them suitable for larger and more integrative phylogenomic studies using other genomic and transcriptomic resources. We analysed datasets containing 37–2077 UCE loci from 98 representatives of all oestroid families (except Ulurumyiidae and Mystacinobiidae) and seven calyptrate outgroups, with a total concatenated aligned length between 10 and 550 Mb. About 35% of the sampled taxa consisted of museum specimens (2–92 years old), of which 85% resulted in successful UCE enrichment.

The smallest beetles and the smallest non-parasitic insects belong to the staphylinoid family Ptiliidae. Their adult body length can be as small as 0.325 mm and is generally smaller than 1 mm. Here we address the phylogenetic relationships within the family using formal analyses of adult morphological characters and molecular data, and also a combination of both for the frst time. Strongly supported clades are Ptiliidae + Hydraenidae, Ptiliidae, Ptiliidae excl. Nossidium, Motschulskium and Sindosium, Nanosellini, and a clade comprising Acrotrichis, Smicrus, Nephanes and Baeocrara. A group comprising Actidium, Oligella and Micridium + Ptilium is also likely monophy- letic.

Patterns of body size distribution are also often studied. The distribution of body size within species is looked at for suggestions of differential mating strategies or niche variation among ontogenetic development. Patterns are also examined among species to determine the effects of competition, environmental factors, and phylogenetic inertia.

However, the concept is widely cited but poorly understood, and only a few forensic cases have successfully applied such a method. Surprisingly, this question has never be taken into account entirely as a cross-disciplinary theme. The use of necrophagous insects as evidence of cadaver relocation actually involves a wide range of data on their biology: distribution areas, microhabitats, phenology, behavioral ecology and molecular analysis are among the research areas linked to this problem. This article reviews for the first time the current knowledge on these questions and analysze the possibilities/limitations of each method to evaluate their feasibility. This analysis reveals numerous weaknesses and mistaken beliefs but also many concrete possibilities and research opportunities.

  • Do Longer Sequences Improve the Accuracy of Identification of Forensically Important Calliphoridae Species?
    Do longer sequences improve the accuracy of identification of forensically important Calliphoridae species? Sara Bortolini1, Giorgia Giordani2, Fabiola Tuccia2, Lara Maistrello1 and Stefano Vanin2 1 Department of Life Sciences, University of Modena and Reggio Emilia, Reggio Emilia, Italy 2 School of Applied Sciences, University of Huddersfield, Huddersfield, United Kingdom ABSTRACT Species identification is a crucial step in forensic entomology. In several cases the calculation of the larval age allows the estimation of the minimum Post-Mortem Interval (mPMI). A correct identification of the species is the first step for a correct mPMI estimation. To overcome the difficulties due to the morphological identification especially of the immature stages, a molecular approach can be applied. However, difficulties in separation of closely related species are still an unsolved problem. Sequences of 4 different genes (COI, ND5, EF-1α, PER) of 13 different fly species collected during forensic experiments (Calliphora vicina, Calliphora vomitoria, Lu- cilia sericata, Lucilia illustris, Lucilia caesar, Chrysomya albiceps, Phormia regina, Cyno- mya mortuorum, Sarcophaga sp., Hydrotaea sp., Fannia scalaris, Piophila sp., Megaselia scalaris) were evaluated for their capability to identify correctly the species. Three concatenated sequences were obtained combining the four genes in order to verify if longer sequences increase the probability of a correct identification. The obtained results showed that this rule does not work for the species L. caesar and L. illustris. Future works on other DNA regions are suggested to solve this taxonomic issue.

We present the first case in the Iberian Peninsula where P. terraenovae was captured during autopsies in Madrid (Spain). In the corpse other nec- rophagous flies were found, Lucilia sericata, Chrysomya albiceps and Sarcopha- ga argyrostoma. To calculate the posmortem interval, the life cycle of P. ter- raenovae was studied at constant temperature, room laboratory and natural fluctuating conditions. The total developmental time was 16.61±0.09 days, 16.75±4.99 days in the two first cases. In natural conditions, developmental time varied between 31.22±0.07 days (average temperature: 15.6oC), 15.58±0.08 days (average temperature: 21.5oC) and 14.9±0.10 days (average temperature: 23.5oC). Forensic importance and the implications of other necrophagous Diptera presence is also discussed.

Diana Gallagher Master’s Project for the M.S. in Entomology An Annotated Bibliography of Archaeoentomology April 2020 Introduction For my Master’s Degree Project, I have undertaken to compile an annotated bibliography of a selection of the current literature on archaeoentomology. While not exhaustive by any means, it is designed to cover the main topics of interest to entomologists and archaeologists working in this odd, dark corner at the intersection of these two disciplines. I have found many obscure works but some publications are not available without a trip to the Royal Society’s library in London or the expenditure of far more funds than I can justify. Still, the goal is to provide in one place, a list, as comprehensive as possible, of the scholarly literature available to a researcher in this area. The main categories are broad but cover the most important subareas of the discipline. Full books are far out-numbered by book chapters and journal articles, although Harry Kenward, well represented here, will be publishing a book in June of 2020 on archaeoentomology.

Randle2 and Sibyl Rae Bucheli2* 1School of Medicine Case Western Reserve University, Cleveland OH, USA 2Department of Biological Sciences Sam Houston State University, Huntsville, TX, USA Abstract In forensic entomology,fly data including maggot age are frequently used to help estimate the time since death.Accurate identification of the maggot to species is critical for time since death estimations. However, within a family, maggots are notoriously difficult to identify to species.In this study, we employ phylogenetic datafrom the mtDNAgenes COI and COII to identify an unknown maggot to species (member of the family Sarcophagidae) harvested from a cadaver in June 2009 in Harrison County, Texas. The most closely related species to our unknown maggot was SarcophagabullataParker 1916, a somewhat common carrion-feeding species in southeastern United States that is now gaininggreater recognition as a forensically significant species. Keywords: Forensic entomology; case study; Sarcophagidae; species were collected despite law enforcement agents reporting the Sarcophagabullata Parker 1916 remains to be in a state of fresh/bloated decomposition.The unknown maggots were identified as members of the family Sarcophagidae Introduction using standard morphological features of the spiracular complex but Decomposition of a large mammalian carcass is greatly accelerated could not be further identified (Peterson 1960).

  • A Five-Year Research Program Is Proposed to Expand the Theory of Community Assembly from Its Current Base of Correlative Inferen
    PROJECT SUMMARY A five-year research program is proposed to expand the theory of community assembly from its current base of correlative inferences to one grounded in process-based conclusions derived from controlled field and laboratory experiments. Northern pitcher plants, Sarracenia purpurea, and their community of inquiline arthropods and rotifers, will be used as the model system for the proposed experiments. There are three goals to the proposed research. (1) Inquiline assemblages that colonize pitcher plants will be developed as a model system for understanding community assembly and persistence. (2) Field and laboratory experiments will be used to elucidate causes of inquiline community colonization, assembly, and persistence, and the consequences of inquiline community dynamics for plant leaf allocation patterns, growth, and reproduction, as well as within-plant nutrient cycling. Reciprocal interactions of plant dynamics on inquiline community structure will also be investigated experimentally. (3) Matrix models will be developed to describe reciprocal interactions between inquiline community assembly and persistence, and inquilines’ living host habitats. As an integrated whole, the proposed experiments and models will provide a complete picture of linkages between pitcher-plant inquiline communities and their host plants, at individual leaf and whole-plant scales. This focus on measures of plant performance will fill an apparent lacuna in prior studies of pitcher plant microecosystems, which, with few exceptions, have focused almost exclusively on inquiline population dynamics and interspecific interactions. Plant demography of S. purpurea will be described and modeled for the first time. Complementary, multi-year field and greenhouse experiments will reveal effects of soil and pitcher nutrient composition on leaf allocation, plant growth, and reproduction.

Young Department of Entomology 445 Russell Labs University of Wisconsin-Madison Madison, WI 53706 Abstract: A survey of Wisconsin Nitidulidae and Kateretidae yielded 78 species through analysis of literature records, museum and private collections, and three years of field research (2000-2002). Twenty-seven species (35% of the Wisconsin fauna) represent new state records, having never been previously recorded from the state. Wisconsin distribution, along with relevant collecting techniques and natural history information, are summarized. The Wisconsin nitidulid and kateretid faunae are compared to reconstructed and updated faunal lists for Illinois, Indiana, Michigan, Minnesota, Ohio, and south-central Canada.
