The Molluscidal Activities of Different Extracts from Jatropha curcas L.against Pomacea canaliculata
摘要
Abstract
[Objective] The aim was to analyze the molluscidal activities of different extracts from J. Curcas against P. Canaliculata. [ Method] Using steeping method, the molluscidal activities of carbinol extracts, water-soluble and lipophilic extracts, the seed oil and defatted seeds oil from roots and leaves of J. Curcas with different concentrations, and Jatropholone B and Curcusone D separated from roots against P. Canaliculata were determined. [Result ] All kinds of extracts showed a significant molluscidal effect on the adult snails at a low concentration except the water-soluble extracts from J. Curcas leaves and roots. The lipophilic extracts of roots showed the best molluscidal effect. The LD50 was 0.10 mg/ml at 24 h, and the treatment with the extract for more than 72 h resulted in a 100% mortality rate of the snails. The LD50 of Jatropholone B was 0. 02 mg/ml at 72 h, while the LD50 of Curcusone D was 0.02 mg/ml at 48 h. [ Conclusion] J. Curcas has a potential value for developing natural pesticides to control P. Canaliculata.关键词
