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.
