IV V Abstract Species identification is the starting point for the formulation of any further ipothesis in insect sciences and they are particularly important in forensic entomology and funerary arcaheoentomology. Two main approaches are currently used for identifying insects, the morphological one, preferred by old-school taxonomists and the more recent molecular one, favoured by non-specialists. Both approaches have respectively some limitations: lack of morphological identification keys, especially for the immature stages and the destruction of the specimens during the DNA extraction, as examples. The development of easy-access identification keys and of non-invasive DNA extraction methods permitting the repeatability of the analyses have been the main target of this thesis. To achieve this aims morphological analysis and DNA based methods were integrated and used on samples belonging to different contexts – forensic, museum and archaeological – and different timeframe – 0 to 1000 years old -. The attention was paid to adults and the poor investigate puparia of flies from each context and the different timeframes. For the DNA analysis commercial kits and homemade digestion buffers were tested on modern and old specimens but applying operational procedure to preserve the morphology of the specimens. More then 10 puparia belonging to species in the family Heleopmyzidae, Sphaeroceridae, Piophilidae, Muscidae and Calliphoridae have been described and illustrated. Forty new DNA sequences, mainly from poor investigated taxa, were generated and 37 deposited in GenBank despite some problems arised, mainly due to presence of PCR inibithors in and on the cuticle. The results, reported in this work, will impact in the anlysis of forensic and archaeological material but as well in the study of museum material, that especialy for the species typus is particularly precius and can not be destroid or altered during the identification process. In addition specific question as the separation and identification of Hydrotaea puparia belonging to different species, the identification of poorly investigated species, the systematic of Sarcophaga species in the subgenus Sarcophaga and the evaluation of pre- Columbian funerary cerimonies have been answered. In addition the pictorial material produced will help entomologists working with fragmented material especially from old VI cases or archaeological sites. Several questions are still open and they request further investigations to be done in the future. VII Acknowledgements The PhD thesis is the result of a journey in which you have to put yourself personally at stake. Firstly, I would like to express my sincere gratitude to the F.L.E.A. group. I could not have imagined having a better team for these three years and the credit for this success belongs to a great leader, Dr. Stefano Vanin. Thanks for the incredible support even in the most discouragement moments of the doctorate course, for your patience, motivation, and advices. Fabiola Tuccia, Jennifer Pradelli, your support was essential, in work and in life. We shared knowledge, joy and fun but also moment of difficulty and you were always there to rejoice or comfort me. Prashasti Singh and Subham Mukherjee, we shared lab knowledge but, in particular, we shared the writing-thesis stress. I really felt no one understood me better than you did in this period. Philip Jackson was right when he said “The strength of the team is each individual member. The strength of each member is the team.” even if he was talking about a basketball team. I would like to thank Dr. Gareth Parkes and Dr. Maria Pala (University of Huddersfield), for their insightful comments and encouragement, but also for the hard questions that motivated me to improve my research from various perspectives. I also would like to thank all the Archaeogenetic group for the constructive suggestions during Lab Meetings. My sincere thanks also go to Lorenzo Munari (expert of Sphaeroceridae family, Museum of Natural History, Venice, Italy), Dr. Andrzej J. Woźnica (expert of Heleomyzidae family, Wrocław University, Wrocław, Poland), Dr. Daniel Martín-Vega (expert of Piophilidae family, Universidad de Alcalá, Madrid, Spain), Dr. Daniel Whitmore (expert of Sarcophagidae family, Natural History Museum, London, UK),

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.

  • Insect Orders V: Panorpida & Hymenoptera
    Insect Orders V: Panorpida & Hymenoptera • The Panorpida contain 5 orders: the Mecoptera, Siphonaptera, Diptera, Trichoptera and Lepidoptera. • Available evidence clearly indicates that the Lepidoptera and the Trichoptera are sister groups. • The Siphonaptera and Mecoptera are also closely related but it is not clear whether the Siponaptera is the sister group of all of the Mecoptera or a group (Boreidae) within the Mecoptera. If the latter is true, then the Mecoptera is paraphyletic as currently defined. • The Diptera is the sister group of the Siphonaptera + Mecoptera and together make up the Mecopteroids. • The Hymenoptera does not appear to be closely related to any of the other holometabolous orders. Mecoptera (Scorpionflies, hangingflies) • Classification. 600 species worldwide, arranged into 9 families (5 in the US). A very old group, many fossils from the Permian (260 mya) onward. • Structure. Most distinctive feature is the elongated clypeus and labrum that together form a rostrum. The order gets its common name from the gential segment of the male in the family Panorpodiae, which is bulbous and often curved forward above the abdomen, like the sting of a scorpion. Larvae are caterpillar-like or grub- like. • Natural history. Scorpionflies are most common in cool, moist habitats. They get the name “hangingflies” from their habit of hanging upside down on vegetation. Larvae and adult males are mostly predators or scavengers. Adult females are usually scavengers. Larvae and adults in some groups may feed on vegetation. Larvae of most species are terrestrial and caterpillar-like in body form. Larvae of some species are aquatic. In the family Bittacidae males attract females for mating by releasing a sex pheromone and then presenting the female with a nuptial gift.

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.

  • Insect Fauna Used to Estimate the Post-Mortem Interval of Deceased Persons
    INSECT FAUNA USED TO ESTIMATE THE POST-MORTEM INTERVAL OF DECEASED PERSONS G.W. Levot Elizabeth Macarthur Agricultural Institute, NSW Agriculture, PMB 8, Camden NSW 2570, Australia Email: [email protected] Summary The insects collected by police at the crime scene or by pathologists at post-mortem from the bodies of 132 deceased persons and presented for comment are reported. The samples were submitted with the hope of obtaining an estimate of the most likely post-mortem interval (PMI) to assist police investigations. Calliphoridae, particularly Calliphora augur, C. stygia, Chrysomya rufifacies and Ch. varipes, Muscidae, particularly Hydrotaea rostrata, Sarcophagidae and Phoridae were the most represented Diptera. Beetles belonging to the Staphylinidae, Histeridae, Dermestidae, Silphidae and Cleridae were collected in a small proportion of cases. The absence of species succession during winter confounded estimates of PMI. Confidence in PMI estimates would increase with greater knowledge of the larval growth rates of common blowfly species, seasonal effects on growth rates and blowfly activity, differences between insects infesting bodies located inside verses outside buildings and significance of inner city sites compared to bushland locations. Further research to address deficiencies in knowledge of these subjects is needed. Keywords: forensic entomology, post-mortem interval (PMI) INTRODUCTION similar circumstances. Estimates of PMI are based on Forensic entomology is the application of the faunal succession of invertebrates colonising, or entomology to forensic science. It is not a new associated with a corpse, and the rate of development science. In the late 1800s the French biologist of some, or all of these organisms.

Abstract The morphology and ultrastructure of the antennal sensilla of male Hydrotaea (Hydrotaea) armipes (Fallén) are examined via scanning electron microscopy in order to highlight the importance of antennal sensilla as a source of morphological characters for taxonomy and phylogeny of Hydrotaea. Antennal scape and pedicel have only one type of sensilla, the sharp-tipped chaetic sensilla, whereas antennal funiculus possesses several types of sensilla, including trichoid sensilla, two subtypes of basiconic sensilla, coeloconic sensilla and clavate sensilla. These results are compared with previously published studies on other fly species, especially on H. (H.) irritans (Fallén) and H. (Ophyra) chalcogaster (Wiedemann), and there are possible uniquely derived characters or diagnostic characters examined on antennal pedicel and antennal fu- niculus, which suggests either affinities and divergence between species at subgenus level.

  • 1 a Checklist of Arthropods Associated with Rat Carrion in a Montane Locality
    1 A checklist of arthropods associated with rat carrion in a montane locality of northern Venezuela. Yelitza Velásquez Laboratorio de Biología de Organismos, Centro de Ecología, Instituto Venezolano de Investigaciones Científicas. Apartado Postal 21827, Caracas 1020-A, Venezuela Tel.: +58-212-504.1052; fax: +58-212-504.1088; e-mail: [email protected] Abstract This is the first report of arthropods associated with carrion in Venezuela, using laboratory bred rats (Rattus norvegicus). Rat carcasses were exposed to colonization by arthropods in neighboring montane savanna and cloud forest habitats in the state of Miranda. The taxonomic composition of the arthropods varied between both ecosystems. Scarabaeidae, Silphidae, Micropezidae, Phoridae, Vespidae and one species of ant, were collected only in the cloud forest. Dermestes maculatus, Chrysomya albiceps, Termitidae and most species of ants, were found only in the savanna. Fourteen species were considered to be of primary forensic importance: Dermestes maculatus, Oxelytrum discicolle, Calliphora sp., Cochliomyia macellaria, Compsomyiops sp., Chrysomya albiceps, Phaenicia cuprina, P. sericata, P. eximia, Fannia sp., Puliciphora sp., Megaselia scalaris, Ravina sp. and Sarcophaga sp. Key words: Coleoptera, Diptera, Forensic entomology, Venezuela. Introduction There is relatively little information available regarding insects associated with animal carrion and human corpses in South America [1]. In Brazil, Moura et al. [2] made a preliminary analysis of the insects of medico-legal importance in Curitiba, in the state of 2 Paraná; Carvalho et al. [3] identified arthropods associated with pig carrion and human corpses in Campinas, in the state of São Paulo. Recently, forensic entomology was applied to estimate the postmortem interval (PMI) in homicide investigations by the Rio de Janeiro Police Department, Brasil [4].

    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by South East Academic Libraries System (SEALS) A global study of forensically significant calliphorids: Implications for identification M.L. Harveya, S. Gaudieria, M.H. Villet and I.R. Dadoura Abstract A proliferation of molecular studies of the forensically significant Calliphoridae in the last decade has seen molecule-based identification of immature and damaged specimens become a routine complement to traditional morphological identification as a preliminary to the accurate estimation of post-mortem intervals (PMI), which depends on the use of species-specific developmental data. Published molecular studies have tended to focus on generating data for geographically localised communities of species of importance, which has limited the consideration of intraspecific variation in species of global distribution. This study used phylogenetic analysis to assess the species status of 27 forensically important calliphorid species based on 1167 base pairs of the COI gene of 119 specimens from 22 countries, and confirmed the utility of the COI gene in identifying most species. The species Lucilia cuprina, Chrysomya megacephala, Ch. saffranea, Ch. albifrontalis and Calliphora stygia were unable to be monophyletically resolved based on these data. Identification of phylogenetically young species will require a faster-evolving molecular marker, but most species could be unambiguously characterised by sampling relatively few conspecific individuals if they were from distant localities. Intraspecific geographical variation was observed within Ch. rufifacies and L. cuprina, and is discussed with reference to unrecognised species. 1. Introduction The advent of DNA-based identification techniques for use in forensic entomology in 1994 [1] saw the beginning of a proliferation of molecular studies into the forensically important Calliphoridae.
