Abstract: The study examines the biological effects of foliar extracts of Cleome arabica L. (capparidaceae) harvested from Ghardaïa region northern Sahara on adult Drosophila Melanogaster reveal the toxicity of this extract on the insect by contact and ingestion. For contact essay , a 100% of mortality rate has been obtained for the pure extract (100%) and rates in order of 72.22%, 61.11%, 44.44% and 5.55% for the concentrations of 80%.60 %, 40%, 20% respectively. A 100% of mortality rate has been obtained for pure extract (100%) and 83.33%, 77.77%, 66.66%, 55.55% for the concentration of 80%, 60%, 40%, 20% respectively. The lethal time (TL50) per contact was 1.6718 min and 1.6728 min, 1.6853min, 1.7544min, 2.8658min for the 100%, 80%, 60%, 40% and 20% doses. And for ingestion essay was 0, 9391; 0.9669; 1.4708; 1.5790; 1.526 hours for the concentrations 100%, 80%, 60%, 40%, 20%, respectively. The lethal dose 50 (LT50) obteined was 0.093831mg / ml per contact; And 0.070971 mg / ml by ingestion The total sugar level increases with the concentration of the aqueous extract, with 51.69 ± 9.25 μg / ml, 72.33 ± 0.18 μg / ml, 99.90 ± 6.53 μg / ml 89.64 ± 6.53 μg / ml, 53.62 ± 7.98 μg / ml, 64.64 ± 0.18 μg / ml reported for concentration 0%, 20%, 40%, 60%, 80% % And 100%, respectively. The maximum increase has been recorded for the 20% and 40% doses. There was an increase in glucose as a function of the dose applied, the maximum glucose level was 87.44 ± 1.57 for the 100% concentration, The high doses of 80% and 100% increase the level of proteins with 58.39 ± 3.08, 59.24 ± 0.60 respectively. It appears that the cholesterol level reported for the control individuals was 58.17 ± 1.18 μg / ml
