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 کاملAssessment of the molluscicidal activities of Tribromosalan, Cartap and Chlorothalonil against Oncomelania hupensis.
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...
متن کاملSynthesis of Ginkgolic Acid Analogues and Evaluation of Their Molluscicidal Activity
Based on the molluscicidal activity of ginkgolic acids (GAs) isolated from Ginkgo biloba L, a series of Z/E isomers of GA analogues were prepared and evaluated for their molluscicidal activities against the host snail Oncomelania hupensis. The results and analysis of the structure-activity relationship revealed that the E-isomers showed better molluscicidal activities than their Z-isomers. Moll...
متن کاملLaboratory and field assessment of molluscicidal activity of B-2 against Oncomelania hupensis, the vector snail of schistosomiasis 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 ...
متن کاملMolluscicidal effect of sanguinarine on Oncomelania hupensis snails
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 expl...
