在日本佐贺研究了间歇灌溉促进水稻生产对稻田蚊子和食幼虫捕食者的影响。蚊子和相关类群的采样浸渍在两个稻田间歇灌溉，并在一个稻田，保持淹没在整个研究期间约1个月。随着间歇灌溉的开始，幼虫蚊子（三带喙库蚊Giles和中华按蚊Wiedemann）的丰度下降，复灌领域最初由第一龄的殖民地。水生节肢动物捕食者和食幼虫鱼类的数量也急剧下降。灌溉渠的水被认为是这些捕食者繁殖季节有限且发育期比蚊子长的主要来源。重复间歇灌溉使水生昆虫群落的丰富度（类群数）下降，但昆虫中蚊子的百分比增加。稻田和相关渠道作为一个整体的操作是必不可少的稻田蚊控制水管理。
Effect of intermittent irrigation to facilitate rice production on rice-field mosquitoes and larvivorous predators was studied in Saga, Japan. Mosquitoes and associated taxa were sampled by dipping in two rice fields subject to intermittent irrigation and in one rice field that remained flooded throughout the study period of approximately 1 mo. With the onset of intermittent irrigation, larval mosquito (Culex tritaeniorhynchus Giles and Anopheles sinensis Wiedemann) abundance decreased; reirrigated fields were colonized initially by first instars. Abundance of aquatic arthropod predators and larvivorous fish also decreased drastically. Water from irrigation canals was considered to be a major source of recolonization by these predators with limited breeding seasons and longer developmental periods than mosquitoes. Richness (number of taxa) of aquatic insect communities decreased, but the percentage mosquitoes among insects increased with repeated intermittent irrigation. Manipulation of rice fields and associated canals as a whole is essential to rice-field mosquito control by water management.
