In order to know the existing macrofauna of the developed plain of the Maya-Maya airport and to master the different invertebrate families that compose it. An environmental study on this macrofauna has been undertaken. The richness in these various fluctuations has been shown. This study allowed us to inventory 817 individuals belonging to 30 species, 9 genera, 37 families distributed in the manner divided into 17 orders, 5 classes and 2 branches. The family most represented as individuals is the Formicidae, i.e. 1747 ind / m2 in plot 4, followed by Blattelidae represented by the species Blattela Germanica 1188 ind / m2 in plot 2. This study allowed us to know the initial state of the macrofauna of the developed plain of the Maya-Maya international airport in Congo Brazzaville and to have an idea of the continental macroinvertebrates found in these environments.
