Английская Википедия:Callicarpenal
Callicarpenal is a terpenoid that has been isolated from plants of the genus Callicarpa (beautyberry).[1] It acts as an insect repellent against mosquitoes (Aedes aegypti and Anopheles stephensi) and fire ants.[1][2] It also has activity against ticks (Ixodes scapularis and Amblyomma americanum).[3]
In comparison to the most commonly used insect repellent, DEET, callicarpenal is only about 21% less effective at preventing mosquito bites.[4]
Callicarpenal was discovered by scientists at the United States Department of Agriculture's Agricultural Research Service who were inspired by reports that Callicarpa americana (American beautyberry) was used as a folk remedy to prevent mosquito bites.[5]
