Scientific Study from the year 2020 in the subject Biology - Micro- and Molecular Biology, grade: A, University of Ibadan, course: Biology, language: English, abstract: A study was carried out on the forensic entomological evaluation of carrion insects of pigs poisoned with paraquat between July and September 2018, on the main campus of the University of Ibadan. Paraquat is a commonly used suicide agent because it is easily available and very cheap. Pigs for the study were obtained from Akinyele meat market in Ibadan, Oyo state.
