Abstract :  β-caryophyllene oxide had stronger repellent and irritant effect than DEET  Ae. albopictus was more sensitive to β-caryophyllene oxide than An. dirus while, knockdown responses (37%) were observed in An. dirus exposed to 1% β-caryophyllene oxide in the contact trial.  β-caryophyllene oxide did not show any phototoxic activity.  None of the tested β-caryophyllene oxide induced a significant increase of micronucleated cells with or without metabolic activation.  β-Caryophyllene oxide could be considered as a safe repellent, effective against mosquitoes.
