Pinto, Hudson Alves;Melo, Alan Lane de;
Revista do Instituto de Medicina Tropical de S?o Paulo , 2010, DOI: 10.1590/S0036-46652010000400008
Abstract: pleurolophocercous cercariae emerged from naturally infected melanoides tuberculata from minas gerais state, brazil, were used to perform experimental infection of laboratory-reared poecilia reticulata. mature metacercariae were obtained from the gills of fishes and force-fed to mus musculus. the adult parasites which recovered from small intestines of mice were identified as centrocestus formosanus. this is the first report of m. tuberculata as intermediate host of this heterophyid in brazil.

Abstract: this study evaluated the relationships of certain allometric measurements in melanoides tuberculatus muller, 1774, in order to develop a statistical model to estimate the biomass of this mollusc species. we measured the total length and aperture of 70 shells. these measurements were correlated with the biomass values to construct exponential and power-function models, and both models showed high coefficients of determination. the exponential model was the better biomass predictor, with a coefficient of determination over 93%. these proposed models may be an effective tool to determine the biomass of m. tuberculatus in eutrophic brazilian reservoirs.
First record of the invasive snail Melanoides tuberculatus (Gastropoda: Prosobranchia: Thiaridae) in the Paran? River basin, GO, Brazil

Brazilian Journal of Biology , 2006, DOI: 10.1590/S1519-69842006000600018
Abstract: the thiarid snail melanoides tuberculatus (müller, 1774), native to asia and east africa was recorded for the first time in the paran? river basin, goiás state. there is no evidence concerning introduction vectors but aquarium releases is the most probable vector. specimens were collected at three different water bodies after twenty-seven rivers were investigated. the possible spread of this species to other habitats and potential effects on native thermal water communities are discussed.
The introduced snail Melanoides Tuberculatus (Muller, 1774) (Mollusca: Thiaridae) in aquatic ecosystems of the Brazilian Semiarid Northeast (Piranhas-Assu River basin, State of Rio Grande do Norte)

Abstract: records of the gastropod melanoides tuberculatus (müller, 1774), family thiaridae, in the piranhas-assu river basin in rio grande do norte reveal the dispersal of this native southeast asian and east african species into aquatic environments of the brazilian semiarid region, including artificial environments (reservoirs) and lotic systems. the eutrophic conditions of the local waterbodies appear to favor the present situation, where this invasive species reaches extremely high densities, sometimes over 10,000 ind.m-2 as in armando ribeiro gon?alves reservoir. these observations indicate the immediate need for new studies on the spatial distribution of the species and its potential impact on the biodiversity and water quality of the waterbodies of the semiarid region of the state. implantation of regular and systematic monitoring of the aquatic resources of the region is urgently required.

Abstract: Melanoides tuberculatus es un gasterópodo cosmopolita que ha invadido y se ha establecido en casi todos los países del continente americano, desconociéndose en la mayoría de los casos el origen de su introducción. En este trabajo se menciona el riesgo de establecimiento de esta especie en áreas de influencia del Río de la Plata como consecuencia de su registro en acuarios de la ciudad de La Plata (Buenos Aires, Argentina) dedicados a la venta de flora y fauna limnética. A principios de 2009, la especie fue identificada a partir de 26 ejemplares procedentes de un comercio, siendo éste el registro más austral de la especie para una localidad de la cuenca del Plata. Revisiones posteriores en 3 locales comerciales de la ciudad confirmaron la presencia de la especie en 2 de ellos. Dicha presencia se relacionó con la adquisición de plantas ornamentales por parte de los establecimientos. La identificación del gasterópodo en la ciudad de La Plata debe considerarse cuidadosamente, debido a las posibles consecuencias que tendría la liberación accidental de este molusco en el Río de la Plata en lo relacionado con el desplazamiento de fauna local y salud pública. Melanoides tuberculatus is a cosmopolitan gastropod that has invaded and has now spread into most countries of the American continent. Introduction pathways remain unknown in most cases. This work draws attention on the colonization risks of this species in the Río de la Plata area as a consequence of its record in flower and pet shops - in the city of La Plata (Buenos Aires, Argentina) - in which limnic species are sold. The species was identified at the beginning of 2009 within a lot of 29 specimens from a shop, and this is the southernmost record of this species in the Plata Basin. Subsequent surveys in 3 commercial shops in the same city revealed its presence in 2 of them. This was related to the purchase of ornamental plants by the shops. Identification of this species in the city of La Plata should be carefully assessed, because of the potential consequences that settlement of this mollusk in the Río de la Plata may have on displacement of the local fauna and on public health.

Abstract: RESUMEN Se describen las larvas de digeneos que se obtuvieron en Melanoides tuberculata (Gastropoda: Thiaridae), molusco dulceacuícola del que se colectaron 125 especímenes en el lago del Jardín Botánico Joaquín Antonio Uribe de Medellín. En el laboratorio se individualizaron y se estimuló la emisión cercariana con una fuente luminosa. El 9,6 % de los caracoles emitió cercarias. Los moluscos emisores se sacrificaron para obtener los demás estadios larvarios. Las larvas se montaron al microscopio, se midieron y luego se dibujaron. Los caracteres morfológicos permitieron establecer la presencia de Centrocestus formosanus (Heterophyidae) y de dos Philophthalmidae. Uno de estos es primer registro para Colombia. Se confirma la sensibilidad de M. tuberculata a infecciones por digeneos, así como la especificidad de los filoftálmidos por moluscos hospedadores de la superfamilia Cerithioidea. Palabras claves: cercarias, digenea, Melanoides tuberculata, Philophthalmidae, Redias. ABSTRACT The larvae of two trematodes found in the freshwater mollusk Melanoides tuberculata (Gastropoda: Thiaridae) are described. 125 snails from the Medellina€ s Botanical Garden Joaquín Antonio Uribe were collected. In the laboratory, each individual was placed alone and stimulated with light in order to have cercaria emission. 9.6% of the snails released cercariae. These were separated in three morphologies. From each one, 15 individuals were measured and drawn. Photographs were taken. Based on their morphological characteritics the presence of Centrocestus formosanus (Heterophyidae) was determined. The other two morphologies were classified in the family Philophthalmidae. One of them constitutes the first register for Colombia. The sensibility of M. tuberculata to infections by digeneans, and the specificity of the family Philophthalmidae to mollusk hosts of the superfamily Cerithioidea are confirmed. Key words: Cercariae, Digenea, Melanoides tuberculata, Philophthalmidae, Rediae.

Abstract: our objective is to evaluate the habitat preference of freshwater snails in relation to environmental factors and the presence of the competitor snail melanoides tuberculatus. in the first phase, snails was collected at 12 sites. this sampling sites presented a degree of organic input. in the second phase 33 sampling sites were chosen, covering a variety of lotic and lentic environments. the snail species found at guapimirim, state of rio de janeiro, displayed a marked habitat preference, specially in relation to the physical characteristics of each environment. other limiting factors for snail distribution at the studied lotic environments were the water current velocity and the amount of organic matter, mainly to physa marmorata, m. tuberculatus, and biomphalaria tenagophila. the absence of interactions between m. tuberculatus and another snails could be associated to the distinct spatial distribution of those species and the instability of habitats. this later factor may favor the coexistence of m. tuberculatus with b. glabrata by reduction of population density. in areas of schistosomiasis transmission some habitat modification may add to the instability of the environment, which would make room for the coexistence of m. tuberculatus and biomphalaria spp. in this way, some of the usual measures for the control of snail hosts would prevent the extinction of populations of biomphalaria spp. by m. tuberculatus in particular habitats.

Abstract: small populations of melanoides tuberculatus (müller, 1774) and biomphalaria tenagophila (d′orbigny, 1835), were found at vila do abra?o, being the first record of these species to ilha grande, angra dos reis, rio de janeiro. they were probably introduced after 2004, perhaps following release from aquaria. the possible spread of these species to other freshwater habitats in the island, their effects on native snails and links with public health are discussed. the record of m. tuberculatus appears to be the first for a brazilian insular area. the recent introduction of these species offers a remarkable opportunity to monitor introduced species and to understand the invasion process in an insular stream in southeastern brazil.
