This paper is a preliminary report on the molluscicidal activity of seed of Camellia sinensis (L) O. Kuntze (SCS). Its LD50 and LD90 were 10 and 16 micrograms/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 micrograms/ml. Juvenile snails may also be killed by this molluscicide.
本文是关于茶籽（SCS）杀螺活性的初步报告。其半数致死剂量（LD50）和90%致死剂量（LD90）分别为10微克/毫升和16微克/毫升。我们还发现，茶籽使钉螺的耗氧量降低了65%，糖原含量降低了80%。该茶籽在8 - 16微克/毫升的浓度下抑制了钉螺从卵孵化到幼螺的过程。这种杀螺剂也可能杀死幼螺。
