本文研究了赤桉三个无性系叶油及其化学成分的抗白蚁活性。在泰国，对台湾乳白蚁（Coptotermes formosanus Shiraki）进行了接触和非接触试验。还研究了杀白蚁机制。抗白蚁试验表明，E.赤桉叶油对C.结果表明，该方法对台湾野螟的LC_（50）为12.68~17.50 mg/g，非接触法为12.65~17.50 mg/皿（100 cm~3）。对伞花烃和γ-松油烯是主要的接触毒性，1，8-桉叶油素是主要的熏蒸毒性。通过对杀白蚁机理的研究，E. Camaldulensis叶油对乙酰胆碱酯酶活性有抑制作用，表现出对C.福尔摩沙人。
The antitermitic activities of leaf oils and their constituents, taken from three clones of Eucalyptus camaldulensis Dehnh. in Thailand, against Coptotermes formosanus Shiraki were investigated in contact and noncontact tests. The termiticidal mechanism was also examined. Antitermitic tests demonstrated that E. camaldulensis leaf oils were both contact toxicants and fumigants to C. formosanus with LC50 values ranging between 12.68 and 17.50 mg/g by the contact method, and between 12.65 and 17.50 mg/petri dish (100 cm(3)) by the noncontact method. p-Cymene and gamma-terpinene were primarily responsible for the contact toxicity and 1,8-cineole was responsible for fumigation. From the investigation of termiticidal mechanism, E. camaldulensis leaf oils exhibited the inhibition of acetylcholinesterase activity and showed the common symptoms of a neurotoxic mode of action against C. formosanus.
