Mode of action and toxicological effects of the sesquiterpenoid, nootkatone, in insects
Significant Findings:"Taken together, these data suggest nootkatone toxicity in D. melanogaster is mediated through GABA receptor antagonism."Abstract:"Nootkatone, a sesquiterpenoid isolated from Alaskan yellow cedar (Cupressus nootkatensis), is known to possess insect repellent and acaricidal properties and has recently been registered for commercial use by the Environmental Protection...

Evaluation of potential use of nootkatone against maize weevil (Sitophilus zeamais Motschulsky) and rice weevil [S. oryzae (L.)](Coleoptera: Curculionidae)
Significant Findings:"The repellency percentage ranged between 46.3 and 93.1% against maize weevils and 39.2–67.2% for rice weevils."Abstract:"Nootkatone is a natural sesquiterpene ketone that shows insecticidal activity against insects and ticks. Its contact toxicity and repellency against two major stored-product insect pests, maize weevil (Sitophilus...
