With the increased concern about the environmental issues in the world, we must shift from heavy use of chemicals to an environmentally-sound termite control measure. The current research was designed to develop the termite control method with little or no chemical to reduce environmentally impacts, and three major subjects were investigated. Those were 1) biological control using an entomogenous fungus : termites are first collected from the colony to be eliminated, infected with the fungus, and released back to their colony members so that ecological behaviors of termites (grooming and cannibalism) accelerate the pace of their death, 2) Physical control using stainless-steel mesh, gravels and any other related materials to build a barrier in the pathway of termites, 3) Bait system using a chitin synthesis inhibitor hexaflumuron.We so far obtained the following results :(1) Respiratory rates and methane emission rates seemed to well reflect physiological disturbance and decline of general activity of termites under various stressful conditions in the laboratory.(2) A chemical substance, that was shown to be repellent to Coptotermes formosanus, was extracted from the ventral gland of Malaysian Dolichoderus sulcaticepu, and was identified as cis, trans-Dolichodial. Further Investigation is needed to conclude its practical feasibility in the management of termite control.(3) Non-destructive acoustic emission (AE) monitoring apparatus was helpful for the evaluating the efficacy of physical barriers over a long period of time. It is possible to build up a novel physical control system combined with AE monitoring device.(4) A survey of monitoring stakes was shown to be effective in evaluating the efficacy of bait system in the field using transferred nests of Coptotermes formosanus. This was repeatedly confirmed in the course of the present investigations.

随着世界对环境问题的日益关注，我们必须从大量使用化学品转向对环境无害的白蚁防治措施。目前的研究旨在开发很少或不使用化学品的白蚁防治方法，以减少对环境的影响，并研究了三个主要课题。 1）使用虫生真菌进行生物防治：首先从蚁群中收集白蚁，将其消灭，感染真菌，然后释放回其蚁群成员，以便白蚁的生态行为（梳理和同类相食）加快其繁殖的速度死亡，2) 使用不锈钢网、砾石和任何其他相关材料在白蚁路径中建立屏障的物理控制，3) 使用几丁质合成抑制剂的诱饵系统到目前为止，我们获得了以下结果：（1）呼吸速率和甲烷排放速率似乎很好地反映了实验室中各种应激条件下白蚁的生理干扰和一般活动的下降。（2）一种化学物质，表明对台湾乳白蚁具有驱避作用，从马来西亚多利霍德尔斯苏卡蒂普腹腺中提取，经鉴定为顺式、反式多利霍迪尔。其在白蚁防治管理中的实际可行性还需要进一步研究。(3)无损声发射(AE)监测装置有助于评估物理屏障的长期有效性。可以建立一个与AE监测装置相结合的新型物理控制系统。(4)监测桩的调查表明，利用台湾乳白蚁转移巢穴，可以有效评估田间诱饵系统的效果。这一点在目前的调查过程中得到了反复证实。
