1. Nanoemulsion containing essential oil from Xylopia ochrantha Mart. produces molluscicidal effects against different species of Biomphalaria (Schistosoma hosts)
BACKGROUND This work describes a chemical study of the essential oil from leaves of Xylopia ochrantha, an endemic Annonaceae species from Brazil, and its activity against Biomphalaria species. Considering its poor solubility in aqueous medium, the essential oil was nanoemulsified to evaluate its action on controlling some mollusc species of genus Biomphala

2. Evaluation of molluscicidal activity of three mangrove species (Avicennia schaueriana, Laguncularia racemosa and Rhizophora mangle) and their effects on the bioactivity of Biomphalaria glabrata Say, 1818
ABSTRACT Schistosomiasis is a disease of global extent reaching populations in social vulnerability. One of the control measures of this parasitosis is the use of molluscicidal substances that can fight snails of the genus Biomphalaria, intermediate hosts of Schistosoma mansoni. The aim of this work was to study the toxic activity of three mangrove species (

3. Molluscicidal effect of Euphorbia umbellata (Pax) Bruyns latex on Biomphalaria glabrata, Schistosoma mansoni host snail
ABSTRACT Euphorbia umbellata (Pax) Bruyns is an easily cultivated shrub, with occurrence in the tropical regions of the American and African continents. Chemical studies have revealed that the latex of this plant is rich in terpene compounds, which are highly toxic to snails Biomphalaria glabrata (Basommatophora: Planorbidae). The aim of this study was to ev

4. Phytochemical and molluscicidal activity of Mikania glomerata Sprengel (Asteraceae) in different lifestages of Subulina octona (Mollusca, Subulinidade)
The objective of this work was to study the molluscicidal activity of aqueous extract of Mikania glomerata on the land snail Subulina octona and to assess the changes caused on the snail's fecundity, growth, hatchability and the offspring produced after exposure. Eggs, newly hatched and 30 day old snails were exposed to the sublethal concentration of M. glom

6. Molluscicidal activity of Moringa oleiferaon Biomphalaria glabrata: integrated dynamics to the control of the snail host of Schistosoma mansoni
The ground seed of Moringa oleifera Lam., Moringaceae, has been evaluated for its molluscicidal activity against the snails Biomphalaria glabrata, Physa marmorata and Melanoides tuberculatus. The results show that M. oleifera is active against B. glabrata (LC50 0.419 g/l; LC90 1.021 g/l and P. marmorata (LC50 0.339 g/l; LC90 0.789 g/l) but has no effect agai

7. ESTUDO ANALÍTICO, AVALIAÇÃO DA TOXICIDADE E ATIVIDADE MOLUSCICIDA DO ÓLEO ESSENCIAL Cinnamomum zeylanicum Blume (CANELA) FRENTE AO CARAMUJO Biomphalaria glabrata (Say,1818) / ANALYTICAL STUDY, EVALUATION OF TOXICITY AND ACTIVITY MOLLUSCICIDAL OF THE ESSENTIAL OIL Cinnamomum zeylanicum blume (SHIN) FRONT THE SNAIL Biomphalaria glabrata (SAY, 1818)
A utilização de plantas para fins medicinais é uma prática antiga. Dentre várias espécies de plantas que contém óleo essencial na sua composição e que podem vir a ser utilizadas no combate a várias doenças destaca-se o óleo essencial extraído das folhas da canela. O óleo da canela pode ser utilizado no combate da esquistossomose, doença endê

9. Molluscicidal Activity of Compounds Isolated from Euphorbia conspicua N. E. Br
O latex de Euphorbia conspicua foi fracionado nas frações triterpênica e irritantes I e II. Da fração triterpênica foram isolados 15 compostos já conhecidos e um novo triterpeno denominado 3β-(E)-cinamoileuforbol. A fração irritante II forneceu o 20-O-acetil-3-O-angeloil-ingenol. A atividade moluscicida dos compostos eufol, 3b-acetoxieufa-8,24-dien

10. The influence of thymol+DMSO on survival, growth and reproduction of Bradybaena similaris (Mollusca: Bradybaenidae)
Bradybaena similaris (Férussac, 1821), commonly known as the Asian trampsnail, is a terrestrial snail native to Asia, introduced in other regions of the world. In Brazil, populations of this land snail are distributed from the state of Amapá in the North to Rio Grande do Sul in the South. This species acts as an intermediate host for parasites and is a dif

12. Molluscicidal activity of Hammada scoparia (Pomel) Iljin leaf extracts and the principal alkaloids isolated from them against Galba truncatula
The molluscicidal activity of Hammada scoparia leaf extracts and the principal alkaloids isolated from them (carnegine and N-methylisosalsoline) were tested against the mollusc gastropod, Galba truncatula, the intermediate host of Fasciola hepatica in Tunisia. The results indicated that the molluscicidal activity was correlated with the presence of alkaloids
