RESUMO
This study describes the chemical composition and antibacterial activities of essential oils of Moroccan Juniperus thurifera L. var. Africana (Cupressaceae). The essential oil of dried leaves was isolated by hydrodistillation, vapohydrodistillation and microwaves. Sixty-four compounds in J. thurifera L. var. Africana oils were identified (79.9%, 92.4% and 98.4% of the oil, respectively). The most abundant compound in J. thurifera L. var. Africana oils is sabinene (38%, 36.2% and 39.4%). Antibacterial activities of J. thurifera essential oils was tested against bacteria Gram ( - ) and Gram (+). The oil is very active against all bacteria tested except Pseudomonas, which turned out to be very resistant.

This study reports the genetic characterization of urban and rural populations of Phlebotomus (Phlebotomus) papatasi Scopoli (Diptera: Psychodidae) in Marrakech, Morocco. Using isoenzymatic analysis, four Moroccan populations were compared with other Mediterranean basin populations from Spain, Cyprus, and Syria. Morphological anomalies were noted in the male genitalia of 5.3% of the specimens collected from Marrakech area. Qualitative analysis of zymogram profiles revealed nine polymorphic enzymes (HK, PGM, PGI, 6PGD, MDH1, MDH2, ICD2, FUM, and ACO) and three monomorphic enzymes (ME, ICD1, and alphaGPDH). Genetic distances clearly separated the populations of western Mediterranean countries (Morocco and Spain) from eastern countries (Syria and Cyprus), but they could not be used to differentiate between urban and rural populations in Marrakech area.
