Abstract
Purpose: To investigate the chemical
composition and insecticidal activity of the essential
oil of the aerial parts of Ostericum grosseserratum against the maize weevil,
Sitophilus zeamais．
Methods: Steam distillation of the
aerial parts of O. grosseserratum during the flowering
stage was carried out using a Clavenger apparatus in
order to obtain its volatile oil content. Gas
chromatography/mass spectrometric (GC/MS) analyses
(HP-5MS column) of the essential oil were performed and
its contact and fumigant activity determined.
Results:
A total of 43 components of
the essential oil were identified. The principal
compounds were (d)-limonene (16.2 %), 4-terpineol (13.5
%), myristicin (11.3 %), γ-terpineol (8.3 %), β-pinene
(5.1 %), β-caryophyllene (4.6 %) and linalool (4.1 %).
The oil exhibited contact toxicity against adult S.
zeamais with lethal concentration (LC50)
value of 17.97 µg/adult. The essential oils also
possessed fumigant toxicity against S. zeamais with LC50
value of 13.70 mg/L air.
Conclusion: The study indicates that
the essential oil of O. grosseserratum has a potential
to be developed into a natural fumigant/insecticide for
the control of grain storage insects.
