Immature mosquito species composition and abundance were studied in irrigated and rain-fed rice fields of North Sulawesi, Indonesia. Irrigated rice fields were characterized by the prevalence of aquatic macrophytes and cyprinodont larvivorous fish, Aplocheilus panchax (Hamilton), but abundance per dip of most aquatic insect predators was lower than that in rain-fed rice fields. Anopheles peditaeniatus (Leicester), Culex vishnui Theobald, and Culex tritaeniorhynchus Giles, were dominant in both irrigated and rain-fed fields, but the abundance of the Culex species was lower in irrigated fields. The effect of irrigation system introduction on regional mosquito abundance cannot be evaluated by the enlarged surface water area alone. Changes in habitat quality, expressed as the abundance per dip (index of density per unit water area), also need to be considered.
在印度尼西亚北苏拉威西省的灌溉稻田和雨育稻田中，对未成熟蚊虫的种类组成和数量进行了研究。灌溉稻田的特点是水生大型植物和食蚊鱼（Aplocheilus panchax，汉密尔顿氏）盛行，但大多数水生昆虫捕食者每次采样的数量低于雨育稻田。在灌溉稻田和雨育稻田中，微小按蚊（Leicester）、致倦库蚊（Theobald）和三带喙库蚊（Giles）均占主导地位，但灌溉稻田中库蚊种类的数量较少。不能仅通过扩大地表水面积来评估引入灌溉系统对区域蚊虫数量的影响。还需要考虑栖息地质量的变化，以每次采样的数量（单位水域面积密度指数）来表示。
