Lymnaea auricularis 발생 과정과 살패(殺貝)에 관한 연구 = Studies on the Lymnaea auricularis Its Development and Molluscicide Effect

다국어 초록 (Multilingual Abstract)

Lymnaea snails lwing in fresh waters and irrigation waterways found in every place our country are injurious ones Carrying Fasciola SP lwing upon men and domestic animals. 26.3 percents of Korean cows and sheep are getting infected with this Fasciola SP.
To prevent this parasitic insects, investigations of its spawning, growth and habitation are made in four reservoirs and one irrigation waterway located in Kwang-ju and Si-hung Provinces. And also we observing the process of its growth in the laboratory, expiriments are made on sterilizing the adult snails by putting several kinds of chemicals.
1. When observing its geographical distribution of regional, seasonal spawning and habitation, we can find that great many numbers of individual object are gatered during May and September and especially from rushing irrigation waterway.
2. The breeding process of Lymnaea snails are easily observed in laboratory and the results of observation tells that the percentage of its spawning an growth are high during May nd September and low during summer and winter.
3. Among many kinds of Chemicals used to sterilize tha adult Lymnaea auricularia CuSO₄ and NaPCP are most effectice. Malathion and CaCN₂ are not so useful.
