 Abstract 


The objective of this work was to contribute to the safeguarding of the forest ecosystem of six villages in Yaoundé through the mastery of edible insects/host plants relationships and the sustainable exploitation of feeding trees larvae and caterpillars consumed and marketed. To achieve these goals, the insects were captured manually and with the use of a net on their host plants and preserved in 70% ethanol and curlpapers. The study found out that,insects consumed in Yaoundé belong to 4 orders of 6 families of 10 species associated with 8 families host trees of 10 genera and 10 species:Lepidoptera-Saturniidae with Imbrasia genus of 7 species living on Lecythidaceae, Euphorbiaceae, Meliaceae, Fabaceae, Anacardiaceae of 7 species;Polyphagous Orthoptera-Acrididae (Acrida sp.) and Pyrgomorphidae (Zonocerus variegatus); Blatodea-Termitidae (Macrotermes falciger); Coleoptera-Curculionidae (Rhynchophorus phoenicis). On the whole, 2110 host plants of edible insects were listed and were used locally as medicinal plants, food, coal trees, firewood and saw log. The most variously exploited species were P. macrocarpus, E. cylindricum and R. heudelotii. Among the causes blocking the durability and the productivity of these edible insects are slash-and-burn farming (37.78 %), saw down of the host plants during harvests (30%), the firewood (11.11%) and the coal industry (3.33%).The investigations on the field showed that the insects represent a running ingredient in the local preparation of dishes.They are mainly eaten as additional food by all the surveyed populations (100%).Top pruning of host trees would reduce their boles and thus facilitate harvesting.
