Molluscicidal effect of sanguinarine on Oncomelania hupensis snails
نویسنده
چکیده
A strong molluscicidal effect of sanguinarine against Oncomelania hupensis snails was demonstrated by immersion test in the present study. A positive relationship between doses, immersion time and the mortality of the snails was exhibited, while the optimal dose and immersion time of application towards the field eradication of snails were suggested. The possible mechanisms of effects were explored by determining the changes in liver aminotransferases (ALT, AST) of the snails and it was revealed that the damage of liver cells was the cause of snail death.

Molluscicidal effect of Eomecon chionantha alkaloids against Oncomelania hupensis snails.
The molluscicidal effects of Eomecon chionantha alkaloids (ECA) against Oncomelania hupensis snails were determined by immersion method. The molluscicidal effect was positively related to ECA concentration, immersion time and temperature of the immersion solution. The mortality of the snails reached 100% by 72 hours in ECA at a concentration of 2.5 mg/l at 25 degrees C. The alanine aminotransfe...
متن کاملThe molluscicidal effect of sodium pentachlorophanate and calcium arsenite on Oncomelania hupensis, a snail host of Schistosoma japonicum in China.
Sodium pentachlorophanate (P.C.P. Na) is now considered as one of the most promising molluscicides. Field experiments with this compound against Oncomelania nosophora in Japan were reported by McMullen and others (1948; 1951), and Hunter and others (1952). Since 1955 this compound has been used for practical molluscicidal purpose in the major endemic areas of schistosomiasis in Japan. In China,...

Molluscicidal activity of B-2 (sodium 2,5-dichloro-4-bromophenol; called as Phebrol and registered in WHO as OMS 3012) was evaluated in a laboratory and the field trials were performed in two different localities in Yueyang city, China, for control of Oncomelania hupensis. B-2 was effective against O. hupensis both in the laboratory and in the field. A dosage of 50 g/m2 in 10% granular form or ...

Molluscicidal activities of Tribromosalan, Cartap and Chlorothalonil were evaluated in the laboratory and the field against Oncomelania hupensis, the intermediate host of Schistosoma japonicum in China. The three chemicals were very effective against O. hupensis in the laboratory. The molluscicidal activities found in the field trials suggest that Tribromosalan and Cartap may be used as practic...
