稻田泽蛙(Rana limnocharis)又叫“梆声蛙”,是我地稻田中数量最大的一类蛙。体型瘦小,不被人们捕捉食用,行动活泼捕食量大,是稻田中稻飞虱、叶蝉、螟虫、稻纵卷叶螟、稻蝽象等多种害虫的重要天敌。据我们1980年小区试验调查,每亩放养泽蛙500头防治稻飞虱、叶蝉,效果达76.7％,放蛙区比对照区飞虱数量减少4.3倍。为对稻田泽蛙作进一步的了解,我们于1981年3月下旬至7月旬和83年4月15日至7月30日在铜仁县谢桥对泽蛙的产卵习性进行了初步的生态观察。现将观察资料整理如下。
Rana limnocharis is also known as “Rana limnocharis” and is the largest group of frogs in my paddy field. It is an important natural enemy of many pests such as rice planthopper, leafhopper, stem borer, rice leaf roller, rice stink bug and so on. According to our 1980 district trial survey, 500 acres of frogs were stocked with 500 rodents to control planthoppers and leafhoppers. The effect was 76.7%. The number of planthoppers in the frog area was reduced by 4.3 times. In order to further understand the paddy field frog, we carried out the preliminary ecology of the spawning habits of the frog in the Xieqiao, Tongren County from April 15 to July 30, 1981 and from April 15 to July 30, Observed. Now observe the data are organized as follows.
