采用熏蒸生物法测定了26种植物精油对日本白蚁的杀虫活性。反应因来源、暴露时间和浓度不同而不同。在所测试的精油中，荷万(Trachyperum Ammi)、多香(Pimenta Dioica)、香菜(Carum Carvi)、小茴香(Anethum Graveolens)、天葵(Pelargonum Graveolens)和山苍子(LitSea Cubeba)的精油具有较强的杀虫活性。用气相色谱-质谱法鉴定了6种挥发油的化学成分。对所鉴定的化合物进行了对日本白蚁的杀虫活性测试。每种化合物的反应随剂量的变化而不同。酚类化合物显示出最强的杀虫活性；此外，醇和醛的毒性比碳氢化合物更大。本文所述的精油和化合物作为潜在的白蚁控制熏蒸剂值得进一步研究。
Plant essential oils from 26 plant species were tested for their insecticidal activities against the Japanese termite, Reticulitermes speratus Kolbe, using a fumigation bioassay. Responses varied with source, exposure time, and concentration. Among the essential oils tested, strong insecticidal activity was observed with the essential oils of ajowan (Trachyspermum ammi), allspice (Pimenta dioica), caraway (Carum carvi), dill (Anethum graveolens), geranium (Pelargonium graveolens), and litsea (Litsea cubeba). The composition of six essential oils was identified by using gas chromatography-mass spectrometry. The compounds thus identified were tested individually for their insecticidal activities against Japanese termites. Responses varied in a dose-dependent manner for each compound. Phenol compounds exhibited the strongest insecticidal activity among the test compounds; furthermore, alcohol and aldehyde groups were more toxic than hydrocarbons. The essential oils and compounds described herein merit further study as potential fumigants for termite control.
