10 Arthropods and Corpses
Arthropods and Corpses 207 10 Arthropods and Corpses Mark Benecke, PhD CONTENTS INTRODUCTION HISTORY AND EARLY CASEWORK WOUND ARTIFACTS AND UNUSUAL FINDINGS EXEMPLARY CASES: NEGLECT OF ELDERLY PERSONS AND CHILDREN COLLECTION OF ARTHROPOD EVIDENCE DNA FORENSIC ENTOMOTOXICOLOGY FURTHER ARTIFACTS CAUSED BY ARTHROPODS REFERENCES SUMMARY The determination of the colonization interval of a corpse (“postmortem interval”) has been the major topic of forensic entomologists since the 19th century. The method is based on the link of developmental stages of arthropods, especially of blowfly larvae, to their age. The major advantage against the standard methods for the determination of the early postmortem interval (by the classical forensic pathological methods such as body temperature, post- mortem lividity and rigidity, and chemical investigations) is that arthropods can represent an accurate measure even in later stages of the postmortem in- terval when the classical forensic pathological methods fail. Apart from esti- mating the colonization interval, there are numerous other ways to use From: Forensic Pathology Reviews, Vol. 2 Edited by: M. Tsokos © Humana Press Inc., Totowa, NJ 207 208 Benecke arthropods as forensic evidence. Recently, artifacts produced by arthropods as well as the proof of neglect of elderly persons and children have become a special focus of interest. This chapter deals with the broad range of possible applications of entomology, including case examples and practical guidelines that relate to history, classical applications, DNA typing, blood-spatter arti- facts, estimation of the postmortem interval, cases of neglect, and entomotoxicology. Special reference is given to different arthropod species as an investigative and criminalistic tool. Key Words: Arthropod evidence; forensic science; blowflies; beetles; colonization interval; postmortem interval; neglect of the elderly; neglect of children; decomposition; DNA typing; entomotoxicology. -

Larvae Reared on Aluminum Phosphide-Treated Rabbits
Reduced body length and morphological disorders in Chrysomya albiceps (Wiedemann, 1819) (Diptera: Calliphoridae) larvae reared on aluminum phosphide-treated rabbits Saeed El-Ashram ( [email protected] ) Foshan University Noura A.

Read Full License Page 1/14 Abstract Assessing the post-mortem interval (PMI) based on the growth and development of insects is a critical task in forensic entomology. The rate of larvae development can be affected by a variety of toxins, including pesticides. Aluminum phosphide (AlP) is a low-cost insecticide that has yet to be entomotoxicologically tested, despite the fact that it is frequently the cause of fatal poisoning. In this study, we measured the body length of Chrysomya albiceps larvae reared on the carcasses of rabbits poisoned with AlP and analyzed the morphological changes of the larvae reared on the carcasses of rabbits poisoned with AlP. The concentration of AlP in the body of the larvae was signicantly lower than in rabbit tissues. Insects from the AlP group had a signicantly lower gain in body length. Furthermore, deformities in the larvae were found. Small respiratory spiracles were found, as well as a deformed small posterior end with hypogenesis of the posterior respiratory spiracles. Thus, disturbed growth and development of carrion ies found at a crime scene could indicate pesticide poisoning, such as aluminum phosphide. -
Question of the Day Archives: Monday, December 5, 2016 Question: Calcium Oxalate Is a Widespread Toxin Found in Many Species of Plants
Question Of the Day Archives: Monday, December 5, 2016 Question: Calcium oxalate is a widespread toxin found in many species of plants. What is the needle shaped crystal containing calcium oxalate called and what is the compilation of these structures known as? Answer: The needle shaped plant-based crystals containing calcium oxalate are known as raphides. A compilation of raphides forms the structure known as an idioblast. (Lim CS et al. Atlas of select poisonous plants and mushrooms. 2016 Disease-a-Month 62(3):37-66) Friday, December 2, 2016 Question: Which oral chelating agent has been reported to cause transient increases in plasma ALT activity in some patients as well as rare instances of mucocutaneous skin reactions? Answer: Orally administered dimercaptosuccinic acid (DMSA) has been reported to cause transient increases in ALT activity as well as rare instances of mucocutaneous skin reactions. (Bradberry S et al. Use of oral dimercaptosuccinic acid (succimer) in adult patients with inorganic lead poisoning. 2009 Q J Med 102:721-732) Thursday, December 1, 2016 Question: What is Clioquinol and why was it withdrawn from the market during the 1970s? Answer: According to the cited reference, “Between the 1950s and 1970s Clioquinol was used to treat and prevent intestinal parasitic disease [intestinal amebiasis].” “In the early 1970s Clioquinol was withdrawn from the market as an oral agent due to an association with sub-acute myelo-optic neuropathy (SMON) in Japanese patients. SMON is a syndrome that involves sensory and motor disturbances in the lower limbs as well as visual changes that are due to symmetrical demyelination of the lateral and posterior funiculi of the spinal cord, optic nerve, and peripheral nerves. -

Preliminary Observations on the Effects of Hydrocortisone

Musvasva, K. A. Williams, W. J. Muller and M. H. Villet Department of Zoology and Entomology, Rhodes University, Grahamstown 6140, South Africa Centre for Aquatic Toxicology, Rhodes University, Grahamstown 6140, South Africa Abstract Larvae of Sarcophaga (Curranea) tibialis (S. tibialis) were reared at constant temperature on chicken liver treated with a steroid or a barbiturate at concentrations that would be lethal, half-lethal and twice-lethal doses for humans. Trends to greater mortality at higher drug concentrations were not statistically significant. Larvae exposed to either drug took significantly longer to reach pupation compared to those in the control, while larvae exposed to sodium methohexital passed through pupation significantly faster than those in the control. No systematic relationship was found between drug concentration and development time of larvae or pupae. The total developmental period from hatching to eclosion did not differ between treatments, implying that estimates of post mortem intervals- (PMI) based on the emergence of adult flies will not be affected by the involvement of these drugs in a case. On the other hand, anomalous pupation spans may indicate the presence of barbiturates. These findings are compared with patterns found in another fly fed other contaminants. Keywords: Sarcophaga tibialis; Larvae; Post mortem intervals; Development 1. Introduction Too often, drug-related deaths are not discovered for days, especially if the victim lives alone, and ensuing decomposition and loss of body fluids can complicate forensic investigations. -

These images were obtained as part of a PRISM-sponsored research project by PRISM student Glen Mahon and his mentor Dr. Peter Diaczuk. Glen Mahon’s pioneering discovery proves what had previously been widely theorized in the field but never documented - that radial fractures appear before tangential fractures when a pellet or bullet penetrates glass. Using images from a high-speed camera purchased with PRISM funding, Mahon documented the specific patterns created when glass breaks mechanically due to an applied force. The images illustrate how radial fractures first spread out from where the force was applied and then tangential fractures occur in a circular pattern around the impact area. -
