Estimating the term…
Compounds, compositions, and methods for controlling an arthropod pest population that employ an eremophilane sesquiterpene parent structure are presented. The compounds have minimal adverse or toxic effects on humans, non-human animals, and the natural environment. The compounds may be isolated from natural sources, semi-synthesized from naturally occurring compounds, or completely synthesized. The compounds may be applied directly to a pest, or the locus of a pest, and function as topical or ingestible toxins. Eremophilane sesquiterpenes 13-hydroxy-valencene, valencene-11,12-epoxide, valencene-13-aldehyde, and nootkatone-1,10-11,12-diepoxide are exemplary compounds.
A pest control agent comprising about 65×10−3 percent (wt:vol) or less isolated nootkatone.
A method for controlling selected arthropods, comprising contacting an arthropod of the Order Siphonoptera or Ixodes species with a pest control agent comprising a pesticidally effective amount of isolated nootkatone.
