I have suggested and supervised the research work of 19 M.Sc. students and three Ph.D. candidates who all successfully obtained their degrees.
I am now supervising the research work of three Ph.D. and 6 M.Sc. candidates. The topics investigated by these candidates deal with insect ecology particularly population dynamics of pests and their natural enemies. New areas include investigations on the desert locust ecology and the role of semiochemicals in its life system.
