Abstract:
The objective of our study is to check the effect of aqueous extract of aerial parts
of Cleome arabica L (Capparidaceae) taken from Oued El-Drin (Ghardaia) northern
Sahara , on third-stage larvae of Culex pipiens ( Diptera, Culicidae) and the effect of
cleom arabica seeds oils on a group formed from 3fungi (funguses) (Candida albicans,
Penicillium species, Alternaria alternata) and 3 kinds of bacteria (Pseudomonas sp,
Stphylococcus sp, Escherichia coli).
The results of our work, haws that whatever the concentration of aqueous extract of
C. Arabica, the mortality rate is100%.
The study of the antimicrobial activity of the extracts of Cleom Arabica seeds oils
a large area resulting in the inhibition of Penicillium sp (30.33 ± 0.58) whereas Condida
albicans has a low area inhibition (10 ± 1 mm) and located in the zone of inhibition for the
microbial species Pseudomonas sp (15.67 ± 1.53) the input or higher by another strain.
The final result is that the extract of this plant can be used as a natural biocide.
