摘 要: | Essential oil from clove buds Syzygium aromaticum L. Merr. & Perry (Myrtaceae) was extracted using petroleum ether in Soxhlet apparatus. The resultant oil contained eugenol (48.92%), caryophyllene (18.55%), α-caryophyllene (3.25%), eugenol acetate (23%), cis-13-docosenamide (3.2 1%), presenting more than 96% of the oil. This oil was examined as a fumigant and repellent agent against adults of the red flour beetle, Tribolium castaneum. Data showed that various concentrations of the oil have revealed dramatic repellent activity against the tested insect, where it gave 100% repellency by 1.0, 0.8, and 0.2% clove oil at 4, 8, 10 min, respectively. The RTs0 and RT95 were 1.1 and 8.0 min at 0.2% and 0.4, 2.6 min at 0.8%, respectively. In addition, fumigation assay has also exhibited strong fumigant activity toward the adults of T. castaneum. At 100 μL oil/L air, mortality was 75, 80 and 100% after 6, 7, and 8 days exposure period with LCs0 and LC95 17 and 70 μL/L air, respectively. The utilization of clove oil for its potential effects against stored product insect is discussed.
