Tropical peri-urban ecosystems are essential for the urban population's well-being through the goods and services they provide. Unfortunately, these ecosystems are subjected to anthropogenic pressures for various reasons. This study aims to assess the diversity and structure of the peri-urban ecosystems that provide the most edible insects in Kinshasa. A total of 360 people were interviewed to identify the two insect species most frequently consumed. The tree inventory was carried out in 50 plots (2500 m2 each), of which 25 were in Acacia plantations, 10 were planted Milletia forests, and 15 were natural Millettia forests. The diameters of each tree, dbh ≥ 10 cm, were measured. Principal component analysis (PCA) was used to distinguish the forest communities. Diversity indices were used to assess floristic variability and structural parameters were used to characterize forest stands. Two insects were identified as being the most commonly consumed in Kinshasa: Gonimbrasia jamesoni (28%) and Cirina forda (27%), found the in Acacia plantation, and in the planted Milletia forests and natural Milletti forest, respectively. The results indicate floristic (higher in the Acacia plantation) and structural variability between stands. The structure of the stands indicates good news for all forests, except the planted forest. The high frequency/dominance of A. auriculiformis and M. laurentii in the peri-urban ecosystems of Kinshasa would therefore be optimal conditions (under natural conditions) for good production of these two caterpillar species.
