对黄檀、阿拉伯相思三种桉树木材的不同部位对两种白蚁的毒力进行了测定。白蚁工人被允许以2克植物及其部分的完整木粉为饲料，包括树皮、边材和心材。每隔24小时从白蚁的肠道中采集鞭毛虫样本，它们的死亡率因所用木材种类及其所用部位的不同而有显着差异。6天后，油桐全部木材部分鞭毛死亡率为100%，油松树皮、边材和心材分别为87.2%、47.61%和100%。而在阿拉伯木虱中，仅树皮在第6天对白蚁鞭毛虫的致死率为44.5%。结果表明，不同木材或其特定部位含有某些特定的有毒化合物，对白蚁肠道鞭毛虫有不同程度的毒性。根据不同木材及其不同部位的生毒性质，对三种木材及其树皮、边材和心材的木质素、苯乙醇可溶成分和α-纤维素含量进行了分析。然而，强烈建议对这些原生动物化合物进行分离、纯化和生化鉴定，以便将其作为商业产品应用于白蚁等对木本植物及其产品造成巨大危害的害虫的防治。关键词：树皮，边材，心材，赤桉，黄檀，阿拉伯相思，白蚁鞭毛
Different parts of three woods of Eucalyptus cammeldulensis , Dalbergia sissoo and Acacia arabica were analyzed for their toxicity potentials against two species of termites ( Heterotermis indicola and Coptotermis heimi ). Termite workers were allowed to feed on 2 g complete wood powder of plant species and their parts, including; bark, sapwood and heartwood. Samples of flagellates were collected after each 24 h from the termites’ gut and they showed a significant variation in their mortality rate as per the wood species and their parts used in the experiments. After six days, mortality rates in flagellates were 100% with all wood parts of E. cammeldulensis , whereas it was 87.2, 47.61 and 100% with bark, sapwood and heartwood of D. sissoo respectively. However, in the case of A. Arabica , only bark inflicted 44.5% mortality on the flagellates in termites on the 6th day. It is revealed from the results that different woods or their specific parts have some specific toxic compounds that inflicted varying degree of toxicity on enteric flagellates of termites. Considering the toxigenic nature of different woods and their respective parts, the three woods; E. cammeldulensis , D. sissoo and A. arabica and their parts barks, sapwoods and heartwoods were analyzed for the presence of water soluble constituents such as lignin, benzene-ethanol soluble components and alpha cellulose contents. However, it is highly recommended that such protozoicidal compounds should be isolated, purified and biochemically characterized in order to apply them as commercial products for the control of pest like termites, which cause a huge damage to woody plants, and their products.
