Leaves and peels samples of eight Citrus species (c. reticulata, C. paradisi, C. sinesis, C. limet/a, C. aurantium, C. grandis 1, C. grandis 2 and C. grandis 3) were hydrodistilled using the modified Clevenger-type apparatus. The yields of essential oils in leaves and peels of Citnts spp. ranged from 0.30% to 2.49% and 7.80% to 34.60% respectively. The oils obtained from leaves and peels were analyzed by Gas Chromatography-Flame Ionization Detector (GC/FID) and a total of 60 and 13 chemical components respectively were identified. The major compounds found in the leaves oils were p-cymene, a-pinene, sabinene, 2,3-dehydro-I,8-cineole, linalool and dihydrolinalool. Whereas, major compounds found in the peels oils of Citnts spp. were o-terpinene, 2,3-dehydro-l,8-cineole, {3-carene and limonene. The relationships among the species were analyzed using cluster analysis by (GCIFID) data. The dendograms indicated similarities in several of the CitntS'S oils. The most potent inhibitory activities against the larvae of Artemia salina given by the oil derived from leaves and peels of C. grandis 1 with LCso value of 63.10 ~g/mL. The peel oils of C. grandis 1 and leaves oils from all Citnls spp. studied (except for C. grandis 1 and C. grandis 3), showed 100% mortality within 1 day at 10% concentration against termites, Coptotermes sp.
