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.

白蚁的控制是美国的一个主要问题。目前使用的木材防腐剂主要有无机砷化合物、五氯苯酚和杂酚油。这些制剂有毒、致癌，并对环境有害。初步研究表明，刺柏的心材和树叶具有很高的杀白蚁活性。这项拟议的研究将使用一种生物方法从雪松和维吉尼亚雪松的心材和叶的提取物中分离出有效的杀白蚁成分(S)，这两种植物目前正被用于生产雪松油。最有活性的部分的临时潮汐活性将与商业白蚁杀虫剂进行比较。产量将从整棵树上确定，以评估该程序的经济可行性。如果成功，这项研究将导致从未充分利用的工厂中制备一种新的、优质的白蚁杀菌剂。
