“…Methods were already described in a previous paper (Chifundera et al, 1993). Snails (Biomphalaria pfeifferi and Lymnae natalensis) and furcocercariae of Schistosoma mansoni were submitted to the saponin extract and the mortality rate was noted after 24 h. The furcocercariae were monitored under binoculars.…”

“…Maesa lanceolata is used as medicine and as piscicide or molluscicide (Apers et al, 1999;Chifundera, 2001). Its saponin fraction is a powerful molluscicide at 1 mg/l and is planned for snail control in the Democratic Republic of Congo where schistosomiasis is widespread (Chifundera et al, 1993;Bagalwa and Baluku, 1997;Baluku et al, 2000). This saponin part extracted from the stem bark seems to be harmful to several aquatic biota.…”

“…However, from an ecotoxicological point of view, this chemical is highly toxic against non-target soft-bodied aquatic organisms and leads to marked decline of them in several areas (da Silva et al 2013, but see Andrews et al 1982 for non-toxic effects on humans). To overcome this challenge, some eco-friendly tools have been developed, including the use of plant-borne compounds as molluscicides to control freshwater snails (Chifundera et al 1993;Brackenbury 1999;Lahlou 2003;Radwan et al 2008;Jaiswal and Singh 2009;Kumar et al 2010;Rapado et al 2011;da Silva et al 2013;Teixeira et al 2012;Singh et al 2010).…”

Mediterranean essential oils as effective weapons against the West Nile vector Culex pipiens and the Echinostoma intermediate host Physella acuta: what happens around? An acute toxicity survey on non-target mayflies

Mosquitoes (Diptera: Culicidae) represent a threat for millions of people worldwide, since they act as vectors for important pathogens, including malaria, yellow fever, dengue and West Nile. Second to malaria as the world's most widespread parasitic disease, infection by trematodes is a devastating public health problem. In this study, we proposed two essential oils from plants cultivated in Mediterranean regions as effective chemicals against mosquitoes and freshwater snails vectors of Echinostoma trematodes. Chemical composition of essential oils from Achillea millefolium (Asteraceae) and Haplophyllum tuberculatum (Rutaceae) was investigated. Acute toxicity was evaluated against larvae of the West Nile vector Culex pipiens (Diptera: Culicidae) and the invasive freshwater snail Physella acuta (Mollusca: Physidae), an important intermediate host of many parasites, including Echinostoma revolutum (Echinostomidae). Acute toxicity of essential oils was assessed also on a non-target aquatic organism, the mayfly Cloeon dipterum (Ephemeroptera: Baetidae). Achillea millefolium and H. tuberculatum essentials oils were mainly composed by oxygenated monoterpenes (59.3 and 71.0 % of the whole oil, respectively). Chrysanthenone and borneol were the two major constituents of Achillea millefolium essential oil (24.1 and 14.2 %, respectively). Major compounds of H. tuberculatum essential oil were cis-p-menth-2-en-1-ol and trans-p-menth-2-en-1-ol (22.9 and 16.1 %, respectively). In acute toxicity assays, C. pipiens LC50 was 154.190 and 175.268 ppm for Achillea millefolium and H. tuberculatum, respectively. P. acuta LC50 was 112.911 and 73.695 ppm for Achillea millefolium and H. tuberculatum, respectively, while the same values were 198.116 and 280.265 ppm for C. dipterum. Relative median potency analysis showed that both tested essential oils were more toxic to P. acuta over C. dipterum. This research adds knowledge on plant-borne chemicals toxic against invertebrates of medical importance, allowing us to propose the tested oils as effective candidates to develop newer and safer vector control tools.

“…Os estudos relativos à avaliação moluscicida de vegetais, que obtiveram resultados positivos de extratos, sugerem que a atividade tóxica das plantas se deve à presença de metabólitos secundários como taninos, saponinas, terpenoides, esteroides e flavonoides, dentre outros (Chifundera et al, 1993;Rey, 2001;Hymete et al, 2005). Treyvaud et al (2000) relaciona a atividade moluscicida de Phytolacca icosandra às saponinas isoladas do extrato metanólico e aquoso das bagas desse vegetal, as quais apresentaram atividade para B. glabrata em concentrações de 200 e 25 ppm.…”

RESUMO: Uma das formas de combate a helmintos que possuem moluscos em seu ciclo biológico é o controle da população malacológica. A tentativa de combater os criadouros naturais de hospedeiros intermediários, através de moluscicidas, tem sido uma das formas almejadas para a redução da incidência de enfermidades, como as esquistossomoses e fascioloses. Essa medida epidemiológica tem se concretizado através da utilização dos moluscicidas sintéticos que, dentre outras desvantagens, trazem danos ao ecossistema. Visando a obtenção de novos compostos, os estudos sobre a potencialidade de produtos naturais moluscicidas têm crescido consideravelmente. Alguns pesquisadores apontam os moluscicidas vegetais como fontes alternativas para o tratamento profilático de parasitoses. Tendo em vista a abrangência, endemicidade e relevância, este trabalho revela um maior enfoque à atividade moluscicida de plantas relacionada às esquistossomíases. Unitermos: moluscicida, vegetal, esquistossomose.ABSTRACT: "Plant molluscicidal activity: a prophylactic alternative". An effective way to combat helminthes having mollusk in their life cycle is by controlling their population. The attempt to battle the natural breeding of intermediary hosts through molluscicides has been the targeted approach to reduce the incidence of such diseases as schistosomiasis and fascioloses. This epidemiological measure has been performed using synthetic molluscicides which, among other drawbacks, cause damages to the ecosystem. In order to obtain new compounds, studies on the potential of natural molluscicides products are increasing. Researchers draw attention to molluscicides plants as alternative sources for the prophylactic management of parasitoses. In view of the scope, significance and endemism, the present work highlights plant activities related to schistosomiasis.
