Onchocerciasis vector breeding along 41 km of the Bussere River in the Wau Area of South-Western Sudan was controlled with temephos (Abate) insecticide for one annual transmission period. Vector biting and transmission was compared to the two years of precontrol data. Up to 70% reductions in vector biting and 80% reductions in transmission were recorded at sites with the highest precontrol levels. The flies invading in the control year (principally those invading from the south-west in the main part of the rainy season) were found to be much less infective - 2390 fly bites would be needed to transmit 100 larvae in the control year, compared to 1490 in the precontrol years. It was concluded that localized vector control could have a major impact on onchocerciasis transmission and that in this, and many other foci in Sudan, permanent reductions could be achieved by causeway removal and selective vegetation clearance.
在苏丹西南部瓦乌地区的布塞雷河41公里河段，用特灭磷（阿灭灵）杀虫剂对盘尾丝虫病病媒繁殖进行了为期一个年度传播期的控制。将病媒叮咬和传播情况与控制前两年的数据进行了比较。在控制前水平最高的地点，病媒叮咬减少了70%，传播减少了80%。发现控制年入侵的苍蝇（主要是雨季主要时段从西南部入侵的苍蝇）感染性低得多——在控制年需要2390次苍蝇叮咬才能传播100条幼虫，而控制前几年为1490次。得出的结论是，局部病媒控制可能对盘尾丝虫病传播产生重大影响，在苏丹的这个地区以及许多其他疫源地，通过拆除堤道和有选择地清除植被可以实现永久性减少。
