Preliminary Studies on Imbrasia oyemensis, A valuable Non-Wood Forest Product in Cameroon

Preliminary Studies on Imbrasia oyemensis, A valuable Non-Wood Forest Product in Cameroon


In many countries throughout Africa, Asia, and Latin America, insects significantly contribute to food security. One widely eaten insect in Cameroon is the Imbrasia oyemensis, an edible caterpillar. The caterpillar primarily feeds on the locally known Sapele tree, which is also exploited for timbr production. In order to understand more about the potential competitive nature between logginf and harvesting I. oyemensis, this study aims to examine some of the unknown factors of the moth species that contribute to its survival. 

Goals & Methods

This article focuses on the morphological traits of trees that make up the habitat of Imbrasia oyemensis. The authors set up "phenological plots" to help better understand the life-cycle of the caterpillar. These plots were located in a forst range that was forest concession certified in the southern region of Cameroon, one that is known for its Sapele. 

Conclusions & Takeaways

The authors' preliminary results indicate that the caterpillar's primary host is the Sapele tree (Entandrophragma cylindricum). They suggest additional research on the chemical content of Sapele leaves and trunks to help identify the ideal conditions for developing Imbrasia oyemensis larvae.
