Pascal Osa Aigbedion-Atalor

Postdoctoral fellow



PhD, Entomology, Rhodes University (2021)

Postdoc supervisor: Prof. Martin Hill

Pascal is an insect ecologist mentored by Prof. Myron P. Zalucki (The University of Queensland), Prof. Martin P. Hill (Rhodes University), and Dr. Samira A. Mohamed (icipe). Pascal works on various applied and basic research areas, including trophic interactions, population ecology, and biological control of invasive species (pests and plants). A substantial amount of his applied research has been on the ecology of natural enemies (extant and exotic) of two devastating invasive species, Tuta absoluta and Chromolaena odorata in Africa. His current research focuses on the chemical ecology of the False Codling Moth (FCM), daring to provide insights into the sex pheromone isomers of FCM from different geographical areas in South Africa to improve control.

Research Interest

  • Crop protection
