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.
