Aedes vigilax is a problem mosquito species prevalent in subtropical Australian coastal wetlands. We evaluate the long-term impacts of runnelling, an environmentally benign habitat modification method, on mosquitoes and the wetland environment. Runnelling uses shallow channels to enhance flushing of the marsh. The method successfully reduced larval numbers to below nuisance levels for the 6.5 year study period. We did not detect any significant difference in the wetland environment between runnelled and unmodified parts of the study area. However, the spatial extent of the effects may have extended beyond the modified area.
维氏伊蚊是澳大利亚亚热带沿海湿地中一种常见的问题蚊虫。我们评估了开沟这一环境友好型栖息地改造方法对蚊虫和湿地环境的长期影响。开沟利用浅沟渠来增强沼泽的水流冲刷。在为期6.5年的研究期间，该方法成功地将幼虫数量减少到了无害水平以下。我们未检测到研究区域内进行开沟改造和未改造部分的湿地环境存在任何显著差异。然而，这种影响的空间范围可能已经超出了改造区域。
