The author reported in the previous pager on his observation of @entity944 of @entity2440 cercaria before penetration into the body of fry such as @entity7136 and @entity2083 . And in these studies, the reason behind the fact was investigated and it was found that the mucous substances on the surface of a certain fishes have a strong wormicidal effect to the larva of @entity2441 . 1. When cercariae of @entity2441 were immersed into the mucous substance of gold fish for three minutes 36 seconds to 4 minutes 20 seconds, into that of Aplocheilus latipes for 4 minutes 30 seconds to 5 minutes 20 seconds, into that of @entity7136 for 5 minutes 15 seconds to 6 minutes l6 seconds, and into that of @entity2083 for 5 minutes 20 seconds to 7 minutes 30 seconds, it was observed that they were all killed. 2. No wormicidal effect against @entity2441 could be observed with the mucous substance obtained from @entity12109 , @entity38823 and @entity43683 . 3. No wormicidal effect against Metagonimus sp. cercaria is observed with the mucous substance obtained from @entity7136 , @entity2083 . 4. The wormicidal effect of the mucous substances obtained from gold fish was destroyed when heated over 60 degrees C. 5. The movements of metacercaria of @entity2441 stopped after 10 minutes application of the mucous substance obtained from @entity7136 and they were killed within 30 minutes. 6. When the adult worms collected from the bile duct of experimentally infected @entity95 for 20 to 60 days, were immersed into mucous substance from @entity7136 , they were killed between 25 minutes and 35 minutes. 7. No wormicidal effect could be observed with the mucous substance obtained from dead @entity7136 , @entity2083 , gold fish, when applied to the adult worms and larvae of @entity2441 .
