项目摘要

A number of the efforts have been made to develop control methods of vectors of deseaes in the world due to insecicide resistance of the target vectors andside effects to thenone-target organisms. Thus the environmental polutions are giving hazard situation not only to human being but also to all the organisms in the world. However, the deseases are still hyghly endemic in the developping countries, espectially tropical areas. In this situation the present workers embarked to develop other control methods, such as isect grouth regurator, physio-ecological and genetic control method; wingsound attraction of the vectors and their ecological physiological characters, and application of carnivorous fish for vector larvae.(1) In the laboratory experiment even the same species there exist several different taxa among sibling groups. They defferetly respond by sound frequencies respectively.(2) In field test, Cx. pipiens and Cx. tritaenirhynchus respond to combined sound more to droning sound as well as their responding sound. This character was applied to the trapping huge numbers of these vectors with combined uscage of dry ice and a hamster due to stimulation by CO_2 gas and animal scent. This kind of trap was applied for the breeding site of Mansonia, Cx. tritaeniorhynchus and anopheline vector of malaria in their endemic areas. All of them gave sucessfull results. This method can also be utilize for the monitouring of the vectors. the integration conrol of these method is under way.

由于目标媒介的抗药性和对非目标生物的副作用，世界上已做出了许多努力来开发防治水稻枯萎病媒生物的方法。因此，环境污染不仅给人类带来了危害，也给世界上所有的生物带来了危害。然而，这种疾病在发展中国家，特别是热带地区，仍然是地方病。在这种情况下，目前的工作人员着手开发其他防治方法，如等位生长调节剂、生理生态和遗传控制方法；媒介生物及其生态生理特性的翼声吸引；以及肉食性鱼类对媒介幼虫的应用。(1)在实验室实验中，即使是同一物种，近缘类群之间也存在几个不同的类群。在田间试验中，CX。Piniens和Cx.三头金丝猴对组合音的反应更多地是对嗡嗡声和它们的响应声。这一特性被应用于用干冰和仓鼠联合使用诱捕大量这些媒介的情况，这些媒介是由于受到二氧化碳气体和动物气味的刺激而被诱捕的。这种诱捕器被应用于曼索尼亚CX的繁殖地。三带喙三带喙库蚊和按蚊在其流行区的传播。他们都取得了丰硕的成果。该方法也可用于对载体的监测。这些方法的集成控制正在进行中。
