从土耳其芳香植物精油中提取了6种主要的单萜类化合物，即香芹酚、1，8-桉叶素、薄荷醇、γ-萜品烯、萜品烯-4-醇和百里酚，测定了它们对拟谷盗（Tribolium confusumdu瓦尔）成虫和卵以及地中海谷盗（Ephestia kuehniella Zeller）幼虫和卵的熏蒸活性。使用的剂量为5.8-184.8毫克/升空气，接触时间为24-96小时。所有6个成分对所有测试的昆虫物种和它们的阶段都表现出不同程度的熏蒸活性。活性最强的成分是香芹酚，在46.2 mg/l空气中暴露24-96 h，除E外，对所有试验昆虫的死亡率均> 90%。kuehniellalarthrin需要更高的剂量，184.8 mg/l。尽管需要46.2- 184.8 mg/l的较高剂量，但γ-萜品烯在26.4-57.5 h后也导致所有试验昆虫99%的死亡率。其次是百里酚和松油烯-4-醇，其在46.2-184.8 mg/l的剂量范围内仅对一种昆虫物种和阶段实现相同的死亡率。成分1，8-桉叶油素和薄荷醇在所用剂量和暴露期下对任何测试的昆虫物种实现了低于99%的死亡率。最耐虫期为E. kuehniellalarva和至少184.8mg/l空气的剂量对于所测试的单萜类化合物的99%死亡率是需要的。
Six major monoterpenoid constituents of essential oils from aromatic plants grown in Turkey namely, carvacrol, 1,8-cineole, menthol, γ-terpinene, terpinen-4-ol and thymol were tested for their fumigant activity against adults and eggs of the confused flour beetle,Tribolium confusumdu Val and larvae and eggs of the Mediterranean flour moth,Ephestia kuehniellaZeller. Doses between 5.8–184.8 mg/l air and exposure periods of 24–96 h were used. All six constituents showed fumigant activity in varying degrees against all tested insect species and their stages. The most active constituent was carvacrol and achieved > 90 % mortality against all test insects at 46.2 mg/l air and an exposure of 24–96 h except forE. kuehniellalarvae which required a higher dose, 184.8 mg/l. Although higher doses of 46.2– 184.8 mg/l were necessary, γ-terpinene also caused 99% mortality in all test insects after 26.4–57.5 h. This was followed by thymol and terpinen-4-ol which achieved the same mortality against only one insect species and stage in a dose range of 46.2–184.8 mg/l. The constituents 1,8-cineole and menthol achieved less than 99 % mortality against any insect species tested at doses and exposure periods used. The most tolerant insect stage wasE. kuehniellalarva and at least a dose of 184.8 mg/l air was needed for 99% mortality with the monoterpenoids tested.
