Activity of Euphorbia splendens var. hislopii N.E.B. (Euphorbiaceae) Latex against Lymnaea columella (Say, 1817) (Pulmonata: Lymnaeidae), Intermediate Host of Fasciola hepatica, Linnaeus, 1758 (Trematoda: Fasciolidae). 2: Limited Field-testing
The molluscicidal evaluation of Euphorbia splendens var. hislopii (Crown of thorns) against Lymnaea columella snails, intermediate host of Fasciola hepatica, in irrigation ditches of the Pisciculture Station at Universidade Federal Rural do Rio de Janeiro, was studied under limited field conditions. An aqueous solution of the latex at 5 mg/l was tested in two irrigation ditches (experimental an...
متن کاملStudy of the embryofeto-toxicity of Crown-of-Thorns (Euphorbia milii) latex, a natural molluscicide.
The crude latex of Crown-of-Thorns (Euphorbia milii var. hislopii) is a potent plant molluscicide and a promising alternative to the synthetic molluscicides used in schistosomiasis control. The present study was undertaken to investigate the embryofeto-toxic potential of E. milii latex. The study is part of a comprehensive safety evaluation of this plant molluscicide. Lyophilized latex (0, 125,...
متن کاملThe molluscicidal activities of some Euphorbia milii hybrids against the snail Indoplanorbis exustus.
The objective of this study was to observe the molluscicidal activities of Euphorbia milli, known as "poysean" in Thailand, against Indoplanorbis exustus. Latex from 12 different E. milii hybrids was screened for its molluscicidal activities. Indoplanorbis exustus were exposed for 24 and 48 hours to the latex at various concentrations ranging from 6 to 25 ppm and mortality rates were recorded. ...
متن کاملMolluscicidal Action of the Latex of Euphorbia splendens var. hislopii N.E.B. (“Christ’s Crown”) (Euphorbiaceae) against Lymnaea columella (Say, 1817) (Pulmonata: Lymnaeidae), Intermediate Host of Fasciola hepatica Linnaeus, 1758 (Trematode: Fasciolidae). 1- Test in Laboratory
The latex action of Euphorbia splendens var. hislopii (Christ’s Crown) against snails Lymnaea columella, intermediate host of Fasciola hepatica, derived from irrigation ditches of the Station of Pisciculture at Universidade Federal Rural do Rio de Janeiro, was studied in the laboratory. Lab bioassays, using aqueous solutions of the latex, varying between 0.1 and 10 mg/l, have proven molluscicid...
متن کاملThe molluscicidal activity of the latex of Euphorbia splendens var. hislopii on Melanoides tuberculata (Thiaridae), a snail associated with habitats of Biomphalaria glabrata (Planorbidae).
The use of the latex of Euphorbia splendens var. hislopii was considered as an effective control method for Biomphalaria glabrata in Sumidouro, Rio de Janeiro. However, the appearance and expansion of the snail Melanoides tuberculata since August 1997, with the concomitant reduction of the population of B. glabrata suggest that competitive exclusion might be taking place. Depending on the susce...
