A survey achieved itself on the collection of the parasitoids (Hymenoptera, agents of the biologic struggle) in the region of Kisangani to the level of two sites: forest reserve of Yoko and domain of hunt of Rubi-Tetle. The collection of the data has been done by two methods to know: net fauchoir and Yellow traps. To the total, 674 specimens of the parasitoids have been captured belonging to 10 super-families and left in 25 families. The analysis of the data gives what follows: The fallow is the more varied with 16 families, consistent of the secondary forest with 16 families and the primary forest with 14 families. For what is some relative abundance by habitat, the secondary forest comes in head with 51,2%,, consistent of the fallow with 31,5% and the primary forest comes to the low of the scale with 17,4%. Concerning abundance by taxon, we say that the following families are represented more: Platygastridae (22,3%), Eulophidae (16,3), Diapriidae (14,1%) Bethylidae and Braconidae (9,6%). All these families participate in the struggle biologic against the devastating bugs of cultures. On the ecological plan, we found in the setting of this survey that some families are specific to the types of habitats. It is for example about the fallow with 5 families (Triphiidae, Orussidae, Ceraphronidae, Scolidae and Eucoilidae); the secondary forest with 3 families (Pompilidae, Gastrupidae and Eurytomidae) and the primary forest with also 3 families (Figitidae, Aphelinidae and Chalcididae). On the other hand the other families are ubiquities.

The Democratic Republic of the Congo alone possess about 181 species of ophidians belonging to 59 genera and 7 families. Kisangani city and surrounding area are a "hot spot" of several zoological groups already studied; while the biology and ecology of ophidians remain unknown in this ecoregion. From the perspective of dominance we got 0.1136 for all species with a high value in the species Boaedon olivaceus followed by the species such as Dipsadoboa viridis and Hapsidophrys lineatus while other remaining species: Atractaspis irregularis, Causus sp, Grayia ornata, Boulengerina annulata, Telothornis kirtlandii, Bitis nasicornis and Naja melanoleuca are less represented in our sample. The representativeness in the total number of individuals collected, the taxa, genera and families were respectively 25; 14; 13 and 4. The family of Colubridae is best represented with 65% of species followed by the family of Viperidae and Elapidae each respectively with 14% of species while that the family of Atractaspididae is less represented 7% of species. The Simpson index gives us 0.8864; the probability that two individuals from the sample are randomly of different species; Shannon Wiener index is 3.4831, which stipulates that the drill Basukwambula is very diversified in species; the equitability value is 0.2328. This index shows a statistically insignificant value; because some species of Ophidians captured in Basukwambula forest are represented by only one specimen in our collection.
