Résumé
Several species of Verbenaceae have been widely used in medicine, and some species of Verbenaceae have been observed good insecticidal activity, such as Lantana camara and Vitex negundo. There is no report about repellent activity of Clerodendrum bungei Steud. (C. bungei) against stored product insects. The chemical composition of C. bungei essential oil (EO) were identified, repellent activity of methanol extract, EO of C. bungei and two main components of EO against T. castaneum, L. serricorne and L. bostrychophila were evaluated for the first time. EO of C. bungei was obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS) and GC. A total of 25 components of the C. bungei EO were identified. The principal compounds in the EO were myristicin (75.0%), 2,2,7,7-Tetramethyltricyclo[6.2.1.0(1,6)]undec-4-en-3-one (4.1%) and linalool (3.4%). Results of bioassays indicated that C. bungei EO exerted strong repellent activity against three target insects. As main constituents, myristicin and linalool also had certain repellency. This work suggests that the EO of C. bungei has promising potential to develop into botanical repellents for the control of pest damage in warehouses and grain stores.

BACKGROUND
Several species of Verbenaceae have been widely used in medicine, and some species of Verbenaceae have been observed good insecticidal activity, such as Lantana camara and Vitex negundo. There is no report about repellent activity of Clerodendrum bungei Steud. (C. bungei) against stored product insects. The chemical composition of C. bungei essential oil (EO) were identified, repellent activity of methanol extract, EO of C. bungei and two main components of EO against T. castaneum, L. serricorne and L. bostrychophila were evaluated for the first time.
RESULTS
RESULTS
EO of C. bungei was obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS) and GC. A total of 25 components of the C. bungei EO were identified. The principal compounds in the EO were myristicin (75.0%), 2,2,7,7-Tetramethyltricyclo[6.2.1.0(1,6)]undec-4-en-3-one (4.1%) and linalool (3.4%). Results of bioassays indicated that C. bungei EO exerted strong repellent activity against three target insects. As main constituents, myristicin and linalool also had certain repellency.
CONCLUSION
CONCLUSIONS
This work suggests that the EO of C. bungei has promising potential to develop into botanical repellents for the control of pest damage in warehouses and grain stores.
