The study of the Hymenoptera fauna associated with the Fabaceae is carried out in different environments in the Northern and Western Algeria. Insect sampling was carried out at seven sites representing three regions with different ecosystems and bioclimatic stages, namely: Algiers, Boumerdes and Tissemssilt. The results obtained show a total of 1022 individuals captured representing 59 taxa, distributed in 46 genera and 18 families. Qualitatively, the Boumerdes region is the richest with 648 individuals; it is followed by that of Algiers then Tissemssilt with respectively 191 and 181. In most of the stations, the dominant family in terms of individuals is that of Apidae whose the rate exceeds 60%. The honey bee Apis mellifera intermissa has a remarkable relative abundance varying between 50% and 89%.

The essential oil of Cytisus triflorus L'Her., a Mediterranean species was obtained by steam distillation and identified by GC and GC-MS. 61 compounds were determined. The oxygenated terpenoidic components constituted the most important fraction (64%) followed by the fatty acids (8.2%) and the hydrocarbonated fractions (10.7%)
