摘要: Essential oil was extracted from the fresh leaves of C. tomentosa through hydro-distillation, using a Clevenger type apparatus. Analysis carried out on combined gas chromatograph-mass spectrometer fitted with an hp-5 ms (5% phenyl methyl siloxane) column at temperature programme 35°c (5 min) increased 10°c/min to 280°c and held for 10.5 min then 50°c/min 285°c. The individual components essential oils were identified GC, GC-MS GC-FID co injection authentic standards. major include: beta phellandrene 26.63%, pinene 15.34%, euginol 6.64%, terpineol 6.02%, terpinen-4-ol 5.24%, ?-cymene 3.19%, geraniol 4.14%, nerolidol 5.14%. repellent action also evaluated Y shaped olfactometer. data obtained analyzed statistical analysis system (sas). ability c. tomentosa: Nerolidol Linalool showed significant repellence all doses. together its may be good choices repellant formulations Keywords: , Sitophilus zeamais, oil, Insect repellent, GC-MS.
