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.
Bush meat constitutes one of the available animal proteins source for many rural people. Pressure on big species is growing because of urban request consumption. Small mammals become topical resource interested for hunting to support family and for sale. This study proposes to estimate hunt fullness on sengis Petrodromus tetradactylus tordayi, one case among other small mammals appreciated at Yoko. We have initiated a follow-up of capture beside villagers during eighteen months.278 specimens come from 107 trap makers divided up 73 young men, 30 adult and 4 old people. The young man input is majority and estimated about 68%. Prospecting habit, seasonality capture has been examined also.
This study wore on the diversity and distribution of ophidians in a few protected areas in the Oriental Province (DR. Congo). The harvest data were performed at Tshuapa Lomami Lualaba Park (TL2), in the Yoko Forest Reserve (RFY) and in the Rubitele hunting area (RBTL). The collections come from the missions of Tshuapa Lomami Lualaba Park (TL2), the Yoko Forest Reserve (FRY) and Rubitele hunting area (RBTL). The Ophidians specimens were captured in actively prospecting night with a snake cane; some specimens of Ophidians were purchased from villagers. In total 91 biopsies were taken from the specimens examined belonging to 7 families 25 genera and 28 species. Using a unique method of catching sight in the three protected areas we find that the dominant species was the horned viper Bitis nasicornis (12.09%), followed by the species Boaedon olivaceus (10.99%) while Grayia smithii, Lycophidion laterale, Dendroaspis jamesoni, Causus maculatus, Natriciteres olivacea, Dasypeltis fasciata, Thrasops jacksonii, Rhamnophis aethiopissa, Thelotornis kirtlandii, Toxicodryas pulverulenta et Hapsidophrys lineatus were less represented with 1.10% for each of them. The index of Shannon - Weiner (H) show that the Yoko Forest Reserve (RFY) (H = 3,898) present a higher diversity of Ophidians than that other protected areas. The Simpson index was 0.81 for Tshuapa Lomami Lualaba park (TL2), 0.918 for Yoko Forest Reserve (RFY) and 0.907 for the Rubitele hunting area (RBTL). The equitability is 0.97; 0.917 and 0.944 respectively for the Tshuapa Lomami Lualaba Park (TL2) for the Yoko Forest Reserve (RFY) and the Rubitele hunting area (RBTL). The Species richness (RS) is 19 for the Yoko Forest Reserve (RFY), 15 for Rubitele hunting area (RBTL) and 6 for Tshuapa Lomami Lualaba Park (TL2).
