Forensic Entomotoxicology. A Study on the Impact of Dichlorvos on Carrion Insects in Domestic Fowls

Research Paper (postgraduate) from the year 2023 in the subject Biology - Zoology, grade: A, University of Ibadan, course: Forensic Science and Zoology, language: English, abstract: The study was conducted on the forensic entomotoxicological evaluation of carrion insects from domestic fowls euthanized with dichlorvos (sniper) insecticide. The research centers on the collection and analysis of insects on the carrions and the impact of the insecticide on them.
It entailed a forensic entomotoxicological evaluation between October and December 2019. The fowls for the study were procured from the main campus of the University of Ibadan. They were then euthanized using 3ml and 5ml of dichlorvos. The adult carrion insects were collected using a sweep net and stored in silica gel. Larvae and pupae were also collected and stored in sample bottles containing 70% ethanol. The temperatures of the environment and the carcasses were measured using an infrared thermometer, while the relative humidity was recorded from a digital hygrometer. The fly families Calliphoridae and Muscidae were the initial colonizers of the decomposing carcass, while Sarcophagidae arrived shortly after the fresh stage of decomposition.
