    The results of our study of the biological activity of the aqueous extracts of the air part of Cleome arabica L. (Capparidaceae) plant of northern Sahara crop in the region of Ghardaïa among larvae of the third stage and larvae Culex pipiens reveal an activity larvicide, total mortality for all concentrations 100 %, 90 %, 80 %, 70 %, 60 %, 50 %, 40% and 30 %; and mortality of order 90% for the two low concentration 20% and 10 %. The lethal dose 50 evaluated because of 0.05191mg /ml . The aqueous extract was tested in vitro by the method of dissemination from a solid disc, for their power inhibitor, screw-to-screws a few microbial strains Staphylococcus sp., Pseudomonas , Escherichia coli, Penicellium sp. Candida albicans. We have revealed the antimicrobial activities variables against different microbial strains tested.
