Entomophagy



Entomofagia in AfricaImportance in Africa

Daily consumption of insects over 100 g (fresh weight) has been reported for morethan hundred ethno-linguistic groups.

Such intake is locally observed during 3-4 months. Insects may represented 70% of animal proteins intake.In some regions, insects are over-collected,and become rare. Management of this ressource is urgent.
