This book was released on 2023-06-27 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Study from the year 2023 in the subject Chemistry - Food Chemistry, grade: A, University of Ibadan, language: English, abstract: A study was carried out on the forensic entomotoxicological evaluation of carrion insects of fishes poisoned with dichlorvos on the main campus of the University of Ibadan. Fishes (Clarias gariepinus) for the study were obtained from the fish farm on the University Campus. The fishes were then euthanized with 5ml of dichlorvos while the control was without poison. Adult carrion insects were collected from the fish carrion using a sweep net. The larvae were collected into a bowl by using a scoop, immobilized with hot water and later placed in sample bottles containing 70% ethanol. Pupae were collected using forceps. Carcass temperature was measured using infrared thermometer while relative humidity was recorded from a digital hygrometer. Calliphoridae and Muscidae were the initial pioneers of the decomposing carcass and were seen during the fresh stage, sarcophagidae was seen shortly after the fresh stage of decomposition. The highest mean temperature value for the fish treated with 5ml Dichlorvos was 31.30C while its lowest mean value was 22.60C. It was observed that the temperature on the ninth day was higher than the other days. This is attributed to the heat generated by the active maggots at that stage of decomposition. Dichlorvos was found to retard the growth of carrion larva as shown in Musca domestica larvae when compared with the control. Fast decomposition rate was recorded due to high ambient and carcass temperature. It can be concluded from this study that carrion insects can be used in solving crime puzzles through the extrication of post mortem intervals in conjunction with environmental variables. Since fish carrion in this study attracted a sizable number of carrion insects, it is recommended that fish be used in future forensic case and experimental studies.

Available in PDF, EPUB and Kindle. Book excerpt: The forensic entomologist turns a dispassionate, analytic eye on scenes from which most people would recoil--human corpses in various stages of decay, usually the remains of people who have met a premature end through accident or mayhem. To Lee Goff and his fellow forensic entomologists, each body recovered at a crime scene is an ecosystem, a unique microenvironment colonized in succession by a diverse array of flies, beetles, mites, spiders, and other arthropods: some using the body to provision their young, some feeding directly on the tissues and by-products of decay, and still others preying on the scavengers. Using actual cases on which he has consulted, Goff shows how knowledge of these insects and their habits allows forensic entomologists to furnish investigators with crucial evidence about crimes. Even when a body has been reduced to a skeleton, insect evidence can often provide the only available estimate of the postmortem interval, or time elapsed since death, as well as clues to whether the body has been moved from the original crime scene, and whether drugs have contributed to the death. An experienced forensic investigator who regularly advises law enforcement agencies in the United States and abroad, Goff is uniquely qualified to tell the fascinating if unsettling story of the development and practice of forensic entomology.
Download or read book Insect Molecular Genetics written by Marjorie A. Hoy and published by Elsevier. This book was released on 2013-10-22 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developed as an introduction to new molecular genetic techniques, Insect Molecular Genetics also provides literature, terminology, and additional sources of information to students, researchers, and professional entomologists. Although most molecular genetics studies have employed Drosophila, this book applies the same techniques to other insects, including pest insects of economic importance. As a text, as a reference, as a primer, and as a review of a vast and growing literature, Insect Molecular Genetics is a valuable addition to the libraries of entomologists, geneticists, and molecular biologists. Features offered by this unique reference source: Detailed illustrations Suggested readings at the end of each chapter Glossary of molecular genetic terms
