This work is a contribution to the study of faun-human interactions in the surroundings of the Kahuzi-Biega National Park.
The subject matter of our study focuses on human reports on the fauna, in the situation where will animals predators being plants, present some risks of human contamination.
In fact, our investigation has shown that certain plants preferred by KBNP primates constitute a common point between the PBNK faun and Bugorhe population.
The microscope analyses done in the laboratory show that the KBNP done in the laboratory show that the KBNP Baboons, pets and Bugorhe citizens have parasites, sometimes common to different groups. This presets the risks of zoo noses and other occasional diseases for both the PNKB faun and the Bugorhe population.

The mosquito netting treated with permethrine 2% mark Olyset Net is effective against the Anopheles gambiae. The resistance of this vector due to this insecticide is more worrying from the third month of use. Mesh of that mosquito would be 4mm permanent contact between humans and the vector which explains the perpetuation of this epidemic in our study area despite the extension of nets made by health agencies.

Artemisia annua and Mentha aquatica are plants, the first being an annual plant of variable size and the second in a perennial grass rependu D.R.CONGO. Both are used because of their toxic activity in Acanthoscelides obtectus and against Plasmodium falciparum. Aqueous extracts, terpene, and steroids from the leaves are equipped with a power that acts anophélinocide for 6 days. The DL100 and the LD50 of total extracts are respectively 0.37g/ml and 0,16g/ml for M. aquatica, 0.16g/ml and 0.08g/ml for A. annua.

Larva of Anopheles gambiae ss were collected in the sites at Lwiro and the surrounding areas, to study the sensibility and resistance of these vectors in front of four insecticides in the entomology laboratory of medicine and parasitology, CRSN-Lwiro. The test was carried on the adult femele vectors, twenty five individuals whose age ranged from two and five days. Indeed, this test concerned four insecticids mainly perméthrine (0.75%), deltaméthrine (0.05%) two components of pyrethrinoïdes, malathion (5%) and lambdacyhalothrine (0.05%) largely used in public health for the vectorial control. After more tests, all the Anopheles population have been noticed sensible to all the precited insecticids. Within an hour of test, Anopheles gambiae presented a certain resistance to deltamethrine with a rate of mortality of 46.6%. Twenty four hours after, the rate of resistance for anopheles raised to 95.5%. Statistically, at .05, between permethrine, malathion and lambdacyhalothrine, the difference is not significant in term of resistance. However, the deltamethrine compared to the three insecticids cited above, displays a significant difference and the vectors are resistant. The vectors of malaria may display a certain resistance to the insecticids owing to their origin and concentration.
