BACKGROUND
Research has shown that the family of grapefruit flavors called nootkatones have significant repellant and toxic effects to Formosan subterranean termites (Coptotermes formosanus Shiraki).
RESULTS
Nineteen synthetic nootkatone derivatives, along with three commercially available nootkatone derivatives, were tested for repellent activity against C. formosanus by a choice assay in a petri dish with a two-step triage procedure. Based on the repellency threshold value, the relationships between structure and activity are discussed.
CONCLUSION
Four derivatives of nootkatone have very high repellency and toxicity to C. formosanus, 9 times the potency of the primary compound nootkatone. Four other compounds have between 2 and 3 times the repellency of nootkatones, and three compounds are equal in their repellency to nootkatone.
背景
研究表明，葡萄柚风味家族的诺卡酮对台湾乳白蚁（Coptotermes formosanus Shiraki）具有显著的驱避和毒性作用。
结果
19 种合成诺卡酮衍生物和 3 种市售诺卡酮衍生物通过两步分诊的选择试验在培养皿中对台湾乳白蚁进行了驱避活性测试。根据驱避阈值，讨论了结构与活性之间的关系。
结论
四种诺卡酮衍生物对台湾乳白蚁具有很强的驱避性和毒性，比原化合物诺卡酮的效力高 9 倍。其他四种化合物的驱避效力是诺卡酮的 2 到 3 倍，三种化合物的驱避效力与诺卡酮相当。
