Essential oils from aerial parts of six aromatic plants were analysed by GC-MS. The major compounds identified were -terpinene (11.5%), cuminaldehyde (26.6%) and -terpinen-7-al (40.6%) in , -anethol (95.2%) in , α-pinene (11.6%), limonene (21.0%), β-caryophyllene (22.3%) and α-humulene (16.7%) in , limonene (40.8%) and artemisia ketone (19.3%) in , -β-ocimene (15.6%), 4-ethyl-4-methyl-1-hexene (24.5%), -tagetone (20.5%) and verbenone (27.2%) in , 1,8-cineole (17.9%),elixene (10.3%) and spathulenol (13.8%) in . Oils with strong insecticidal activity on and were from (LC = 4 µl/L; LC = 10 µl/L) and (LC =10.19-12.57 µl/L; LC =20 µl/L). Scents of and were strong insecticides on (LC =7.02-7.17 µl/L; LC =10.00-20.00 µl/L). The insecticidal activity was associated to the whole content of C10 molecules and oxygenated constituents. The oil is promising as protective agent of nut products.
