摘要
本文初次报告了茶树籽[SeedofCameliasinensis(L)O.Kuntze]具有杀死钉螺的作用。LD50及LD90分别为10μg/ml及16μg/ml左右。茶树籽浓度为16μg/ml时可抑制2-5d卵龄的螺卵孵化成幼螺。应用16μg/ml时也有杀死幼螺的作用。当用8μg/ml作用钉螺24h后耗氧量降低65%,而10μg/ml的茶树籽浓度降低钉螺糖原含量约80%。
This paper is a preliminary report on the molluscicidal activity of seed of Camellia sinensis (L) O. Kuntze (SCS).Its LD 50 and LD 90 were 10 and 16 μg/ml,respectively.We found also SCS inhibited oxygen consumption 65% and glycogen content of Oncomelania snail by 80%.The activity of hatching eggs to juvenile snails was inhibited by this seed at 8-16 μg/ml.Juvenile snails may also be killed by this molluscicide.
