The worldwide resurgence of malaria has become a major public health problem. New methods of controlling the vectors of the disease are required, and we therefore studied the biological control of Anopheles albimanus by Romanomermis culicivorax in Colombia. The investigation was carried out in El Valle and Nuquí, two towns on the northern Pacific coast of the country. All of the mosquito larval habitats surrounding El Valle were seeded with the eggs and adults of R. culicivorax. The nematode established itself in the new habitat and recycled over 27 months. The larval population of A. albimanus, the only malarial vector detected in the two towns, decreased in El Valle. In contrast, no change in the larval populations of the vector was detected in ponds located near Nuquí, the untreated control town. A rapid and progressive decrease of the prevalence of malaria among schoolchildren in El Valle was observed during the 2-year evaluation period.
疟疾在全球范围内的再度流行已成为一个重大的公共卫生问题。需要新的疾病媒介控制方法，因此我们在哥伦比亚研究了食蚊罗索线虫对白纹伊蚊的生物防治作用。调查在该国北太平洋沿岸的两个城镇埃尔瓦莱和努基进行。在埃尔瓦莱周围所有蚊子幼虫栖息地都播撒了食蚊罗索线虫的卵和成虫。线虫在新栖息地定殖并循环了27个月。在埃尔瓦莱，两个城镇中唯一检测到的疟疾媒介白纹伊蚊的幼虫数量减少了。相比之下，在未处理的对照城镇努基附近的池塘中，未检测到该媒介幼虫数量的变化。在为期两年的评估期内，观察到埃尔瓦莱学童中疟疾患病率迅速且逐步下降。
