Abstract

The chemical composition of the essential oils of L. stoechas and E. globulus were studied by gas
chromatography mass spectrometry. 1,8-cineole (31.42% in the E. globulus oil and 10.10% in the L.
stoechas oil) identified as the major components in the oils. The insecticidal effects of the essential
oils were evaluated by fumigation method. Probit analysis showed that the larvae and eggs were
more susceptible to the L. stoechas oil than to the E. globules oil at 24 h exposure time. In contrary,
adults and pupae were more susceptible to E. globules oil than L. stoechas oil. Mortality increased as
the doses of essential oils and exposure times increased. These findings revealed the strong insecticidal
activity of essential oils of L. stoechas and E. globulus and it may be used in grain storage against T.
castaneum in order to decrease detrimental effects and risk of utilization of synthetic insecticides.
