RESUMO

OBJETIVO: el estudio se realizó en el municipio Yaguajay, provincia Sancti Spíritus con la finalidad de identificar las especies de moluscos presentes en los ecosistemas fluviales, así como su distribución y abundancia en cada reservorio. MÉTODOS: se analizaron los años 2005 y 2006, mediante 2 muestreos por año, que abarcaron tanto el período lluvioso como el poco lluvioso, se muestrearon 20 reservorios donde se determinaron los moluscos fluviátiles presentes, los datos se procesaron en el programa computarizado Excel XP y para la realización del análisis estadístico se utilizó el procesador SPSS versión 8 realizando tablas de contingencia de 4 x 4. RESULTADOS: se identificaron 10 especies en 2005, Tarebia granifera resultó la más distribuida y abundante, seguida por Marisa cornuarietis. En el 2006, 14 especies y también las antes mencionadas fueron las más distribuidas. Se constató que en la época de lluvia fue donde mayor cantidad de ejemplares se colectaron en los 2 años estudiados, además se demostró que no hubo una correlación significativa entre la aparición de las especies de moluscos y peces en los veinte reservorios estudiados. CONCLUSIONES: el municipio Yaguajay posee una fauna de moluscos fluviales que se puede considerar como amplia si se tiene en cuenta que se identificaron 14 especies, de las cuales, 4 resultaron hospederas intermediarias para la transmisión de fasciolosis, esquistosomosis y angiostrogylosis; existe una estrecha relación entre la malacofauna fluviátil con la vegetación(AU)


OBJECTIVE: the study carried out in Yaguajay, Sancti Spíritus province was aimed at identifying the mollusk species present in the freshwater ecocystems as well as their distribution and abundance in each reservoir. METHODS: two years 2005 and 2006 were analyzed through 2 samplings per years covering the rainy and the dry season; 20 reservoirs were sampled to determine the present freshwater mollusks. Data were processed by Excel xp and the statistical analysis used SPSS version 8 processor and 4 x 4 contingency tables. RESULTS: ten species were detected in 2005, being Tarebia granifera the most distributed and abundant followed by Marisa cornuarietis. It was observed that the highest amount of mosquitoes was collected in the rainy season during the two years under study in addition to proving that there was significant correlation between the occurrence of mollusk species and fish in the 20 researched reservoirs. CONCLUSIONS: Yaguajay municipality exhibits wide freshwater mollusk fauna if one takes into account the 14 identified species of which 4 turned out to be intermediate hosts for fascioliasis, schistosomiasis and angiostrongyliasis. There is close relation between freshwater malacofauna and vegetation(AU)

RESUMO

The study was carried out in the municipality of Yaguajay in theprovince of Sancti Spiritus, Cuba, with the objective of identifyingspecies of mollusks present in the fluvial ecosystems, as well as theirdistribution and abundance in each reservoir. The years analyzed werebetween 2005 and 2006, in which two samplings were taken, oneduring the rainy and the other in the dry season. A total of 20reservoirs were used where the presence of river mollusks wasdetermined. For the statistical analysis the software SPSS version 8was utilized to draw 4 x 4 tables of contingency. A total of 10 specieswere identified in the year 2005 and 14 species in 2006.In both cases,Tarebia granifera was the most abundant and distributed , followed byMarisa cornuarietis , with a larger quantity of specimen in year 2006than in 2005. The results obtained verified that in the two yearsstudied, the largest quantity of specimen was found during the rainyperiod. Besides it was demonstrated that there was no significantcorrelation between the presentation of the fish and mollusk speciesand the twenty reservoirs studied. It was made evident that thetemperature, salinity, pH, concentrations of chloride, ammonia,ammonium and nitrate ions were limiting abiotic factors for theexistence of aquatic organisms, especially mollusks(AU)

RESUMO

OBJETIVO: se realizó un estudio de cohorte en los Consejos Populares de Báez y Guaracabulla, pertenecientes al municipio Placetas, provincia Villa Clara, para determinar la eficacia de 3 especies de peces fluviales: Gambusia punctata Poey, 1854, Gambusia puncticulata Poey, 1854 y Poecilia reticulata Peter, 1895, en el control de larvas de mosquitos en depósitos utilizados por la población para almacenar agua. MÉTODOS: la investigación se inició en el mes de abril de 2006 y culminó en mayo de 2007, se seleccionaron solo los tanques bajos (interior y exterior de las viviendas) por ser más factibles de evaluar, se trabajó con una muestra de 1 740 depósitos que se dividieron en 2 grupos, los cuales se evaluaron por espacio de 1 año. RESULTADOS: el riesgo de encontrar focos de mosquitos fue superior en el grupo de depósitos que no estaban expuestos a la presencia de peces, la diferencia de riesgo permitió plantear que por cada 100 depósitos tratados con peces, se logró evitar 8 focos de mosquitos. CONCLUSIONES: los peces larvívoros constituyen una excelente alternativa contra las poblaciones larvales de culícidos en depósitos utilizados por la población para almacenar agua, que resulta un factor de protección ante la incidencia de focos de mosquitos(AU)


OBJECTIVE: a cohort study was conducted in People´s councils in Báez and Guaracabulla located in Placetas municipality, Villa Clara province, for the purpose of determining the effectiveness of three river fish called Gambusia punctata Poey, 1854, Gambusia puncticulata Poey, 1854 y Poecilia reticulata Peter, 1895 in the control of mosquito larvae inside water reservoirs used by the population. METHODS: the study began in April 2006 and ended May, 2007; the selected water tanks were placed inside and outside the houses) since they were more easy to be evaluated. The sample covered 1 740 tanks divided into 2 groups and evaluated for one year. RESULTS: the risk of finding mosquito foci was higher in the group of reservoirs non-exposed to the action of fish; this difference allowed stating that 8 mosquito foci were prevented per every 100 reservoirs treated with fish. CONCLUSIONS: larvivorous fish are an excellent choice to treat Cullicidae larval populations existing in water tanks and also a protective factor against incidence of mosquito foci(AU)
