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.

Agricultural production constitutes one of the important economic development factors that generates important incomes. Among many Insects, Acarina, Birds, Mammals and diseases that attack crops, the stinking locust, Zonocerus variegatus (Hyménoptère : Pygomorphidae) is a fearsome devastater of crops in the region. This study was conducted to study the population, the distribution of Zonocerus variegatus, its action modes in the field, and to identify its parasitoids in Kisangani. The study was carried out on food cultivation fields. Data were collected from July 2015 for six months, using a sweeping net. Two field works were conducted monthly. Stinking locusts were collected on fields and parasitoids around the fields (fallowland). Z. variegatus develops in 7 post-embryonic stages of which six larval and one adult stages. The data analysis showed abundance of larvae, from stage 1 to 6. Zonocerus variegatus larva appeared superior to the one of stage 7. We observed that larvae are more damaging than adults. 22.31% of Zonocerus variegatus specimens were collected on cassava fields while 5.03% were captured on maize and cassava fields. We collected more Zonocerus variegatus in March (32.6%). Their abundance also proves their aggressiveness to crops. In total, twenty families of parasitoids were collected and distributed into seven super-families. We captured more parasitoids in February (32.83%) than in other months. May is less rich with 4.60%. Scelionidae family largely dominates the others with 23.64% parasitoid specimens, followed by Bethylidae 20.08% and Platygastridae 16.70%. The poorest families are Charipidae (0.19%) and Tanaostigmatidae (0.19%).
