Bioresources of Termiticides from Junipers (Juniperus ashei and J. virginiana)

白蚁的控制是美国的一个主要问题 States. 目前，主要的木材防腐剂 无机砷化合物、五氯苯酚和 木馏油 这些物质有毒、致癌， 对环境有害。 初步研究显示， 杜松（Junipers）的心材和树叶 高杀白蚁活性。 该研究将使用一个 分离活性杀白蚁剂的生物测定 从J. ashei和J. virginiana，目前是两个物种， 用于生产雪松油。 的 最具活性的组分的白蚁活性将是 与商业杀白蚁剂相比。 收益率将 从整棵树上确定，以评估经济效益 程序的可行性。 如果成功的话，这项研究将导致编写一份 新的、上级类杀白蚁剂， 厂

The control of termites is a major problem in the United States. At present, the principal wood preservatives used are inorganic arsenic compounds, pentachlorophenol and creosote. These agents are toxic, carcinogenic and environmentally hazardous. Preliminary research has revealed that the heartwood and leaf of the junipers (Junipers) have high termiticidal activity. The proposed research will use a biological assay to isolate the active termiticidal component(s) from extracts of the heartwood and leaves of J. ashei and J. virginiana, two species which are currently harvested for the production of cedarwood oil. The termicitidal activity of the most active fractions will be compared to that of commercial termiticides. The yields will be determined from whole trees in order to asses the economic feasibility of the procedure. If successful, the research will lead to the preparation of a new, superior class of termiticides from and under-utilized plant.
