Studies on mosquito breeding and its control through Gambusia affinis in nursery and paddy fields after transplantation of seedlings were carried out during June to October 1991 in about 10 ha rice field area. Six anopheline species, viz. An. culicifacies, An. annularis, An. subpictus, An. nigerrimus, An. barbirostris and An. aconitus, and four culicine species, viz. Cx. tritaeniorhynchus, Cx. bitaeniorhynchus, Cx. quinquefasciatus, and Aedes sp. could be identified. These were found breeding in rice fields with fluctuations in their percentage composition, exhibiting species succession in different months. G. affinis survived well in submerged rice fields and provided 87.8% mosquito larval control. In rice fields which exhibited intermittent drying up leading to formation of pools, puddles etc., moderate larval control was achieved. However, in nursery rice fields, this method was not applicable. Mosquito larval control through larvivorous fish in rice fields can be achieved but the method has limitations.
1991年6月至10月期间，在约10公顷的稻田区域开展了关于稻田蚊虫滋生情况以及通过食蚊鱼（盖氏食蚊鱼）进行控制的研究。已鉴定出6种按蚊，即嗜人按蚊、环纹按蚊、伪杂鳞库蚊、黑须按蚊、须喙按蚊和乌头按蚊，以及4种库蚊，即三带喙库蚊、二带喙库蚊、致倦库蚊和伊蚊属。这些蚊虫在稻田中滋生，其百分比组成存在波动，在不同月份呈现出种类演替。盖氏食蚊鱼在淹水的稻田中存活良好，对蚊幼虫的控制率达87.8%。在出现间歇性干涸并形成水坑、小水洼等的稻田中，实现了对幼虫的适度控制。然而，在秧田，这种方法并不适用。通过稻田中的食蚊鱼控制蚊幼虫是可行的，但该方法存在局限性。
