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.

由于目标病媒对杀虫剂的抗性和对单一目标生物的副作用，世界上已经做出了一些努力来开发疾病病媒的控制方法。因此，环境污染不仅给人类，而且给世界上所有的生物都带来了危害。然而，这些疾病在发展中国家，特别是热带地区仍然高度流行。在这种情况下，目前的工作者着手开发其他控制方法，如昆虫生长调节剂、生理生态和遗传控制方法；媒介生物的翼声吸引及其生态生理特性，以及肉食性鱼类对媒介生物幼虫的应用。(1)在实验室实验中，即使同一物种在兄弟群中也存在几个不同的分类群。它们对声音频率的反应不同。(2)现场试验中，Cx。库蚊和Cx。三带喙龙对组合声音的反应更像对嗡嗡声的反应。利用这一特性，利用co2气体和动物气味的刺激，用干冰笼和仓鼠笼联合诱捕了大量的病媒生物。该诱捕器应用于大鲵孳生地。三带喙蚊和按蚊是其流行地区的疟疾媒介。他们都取得了成功。该方法也可用于病媒监测。这些方法的综合控制正在进行中。
