项目摘要

Impact of rice field development on disease vectors was investigated at three research sites in Central Sulawesi, North Seram, and West Timor, all in east Indonesia. Observation was made for mosquitoes transmitting malaria, filariasis and dengue fever, flies involved in mechanical transmission of pathogens, horseflies biting humans and livestock, rats as reservoir hosts for zoonosis, conditions of human dwellings, people's knowledge about mosquitoes and mosquito-borne diseases, and anti-mosquito measures.In Centrak Sulawesi, changes following the deforestation for rice field development were investigated for four years. Irrigation canal construction was delayed due to economic and technological reasons and most parts of the deforested lands have remained as waste lands which may produce many mosquito breeding habitats.In North Seram, changes in transmigration villages after their establishment were investigated. Throughout the new villages just established and older ones up to 15 years … More after establishment, the most important mosquito breeding habitats were ditches where domestic waste water was discharged. In newly established irrigated rice fields, mosquito larvae often occurred at very high densities due to the scarcity of predacious natural enemies.I n West Timor, mosquito breeding habitats were investigated at the dam construction site, rain-fed rice field areas and upland crop areas with associated villages, and, for comparison, irrigated rice field areas with associated villages. In the dry season, mosquito breeding habitats in non-irrigation areas were few and almost limited to river-bed pools and containers in and around houses to keep water. This observation has to be continued until 2002 when the non-irrigation areas will be irrigated by the new dum and canals.Species composition and abundance of flies, horse flies and rats were investigated in relation to environmental conditions. Questionnaire studies revealed that people in villages with irrigated rice fields know mosquitoes and mosquito-borne disease better and implement anti-mosquito measures more extensively, as compared to people in villages without irrigation.

在印度尼西亚东部的中苏拉威西、北塞拉姆和西帝汶的三个研究地点调查了稻田开发对疾病媒介的影响。对传播疟疾、丝虫病和登革热的蚊子、参与病原体机械传播的苍蝇、叮咬人类和牲畜的马蝇、作为人畜共患病宿主的老鼠、人类居住条件、人们对蚊子和蚊子传播疾病的认识以及灭蚊措施进行了观察。由于经济和技术原因，灌溉渠的建设被推迟，大部分被砍伐的土地仍然是荒地，这可能会产生许多蚊子繁殖的栖息地。在北塞拉姆，移民村庄成立后的变化进行了调查。在刚刚建立的新村庄和最多15年的老村庄中， ...更多信息在建立后，最重要的蚊子滋生地是排放生活污水的沟渠。在新建立的灌溉稻田，蚊子幼虫往往出现在非常高的密度，由于缺乏捕食性的天敌，在西帝汶，蚊子繁殖栖息地进行了调查，在大坝建设现场，雨水灌溉稻田地区和高地作物地区与相关的村庄，并进行比较，灌溉稻田地区与相关的村庄。在旱季，非灌溉地区的蚊子繁殖地很少，几乎仅限于河床水池和房屋内及周围的蓄水容器。这种观察一直持续到2002年，当非灌溉地区将由新的垃圾场和运河灌溉时，苍蝇，马蝇和老鼠的物种组成和丰度与环境条件的关系进行了调查。问卷调查显示，与没有灌溉的村庄相比，有灌溉稻田的村庄的人更了解蚊子和蚊媒疾病，并更广泛地实施灭蚊措施。少
