The primary objective of this study is to examine the entomotoxicological impacts of paraquat dichloride herbicide on carrion insects in a forensic context.
Conducted at the University of Ibadan, Nigeria, the research explored the effect of paraquat on rabbit carcasses and the associated carrion insect populations. Dominant insect families were Calliphoridae and Muscidae, with Sarcophagidae also present but less dominant.
