Natural enemies of water hyacinth in the Argentine northeast and the possibilities of its applications to theirs biological control.

In the lentic shallow water bodies related to the Paraná and Paraguay rivers, the water hyacinth (Eichhornia crassipes) forms dense populations that may cover the entire surface of the water, determining strong limnological changes with severe negative impacts on other aquatic communities. Lower tem...

Enemigos naturales de Eichhornia crassipes en el nordeste argentino y posibilidades de su aplicación al control biológico Poi de Neiff, Alicia Neiff, Juan José Bonetto, Argentino In the lentic shallow water bodies related to the Paraná and Paraguay rivers, the water hyacinth (Eichhornia crassipes) forms dense populations that may cover the entire surface of the water, determining strong limnological changes with severe negative impacts on other aquatic communities. Lower temperatures and hydrological factors—particularly river floods—regulate the areal cover and density of such populations. However, as the progressive damming of the rivers reduces the impact of floods, the large populations of water hyacinth may represent a real risk to biological productivity, water quality, navigation, recreational activities, and several other practical purposes. This paper deals with the evolution of the plants and the associated fauna in natural populations of water hyacinth in some ponds and oxbows related to the Paraná River in Chaco Province (Argentina), over the course of an annual cycle, with the aim of contributing to the development of biological control methods. Vegetal and animal fluctuations are discussed in order to determine the quantitative damage to the plant, along with some observations on the biology of potential control agents. En los cuerpos de agua lentos y poco profundos asociados a los ríos Paraná y Paraguay, el camalote (Eichhornia crassipes) forma poblaciones densas que pueden cubrir toda la superficie del agua, provocando cambios limnológicos significativos con un impacto negativo severo sobre otras comunidades acuáticas. Las bajas temperaturas y los factores hidrológicos —particularmente las crecidas de los ríos— regulan la cobertura superficial y la densidad de dichas poblaciones. Sin embargo, a medida que el embalsamiento progresivo de los ríos reduce el impacto de las crecidas, las grandes poblaciones de camalote pueden representar un riesgo real para la productividad biológica, la calidad del agua, la navegación, las actividades recreativas y diversos otros usos prácticos. Este trabajo trata sobre la evolución de las plantas y la fauna asociada en poblaciones naturales de camalote en algunos estanques y meandros abandonados relacionados con el río Paraná en la provincia del Chaco (Argentina), a lo largo de un ciclo anual, con el objetivo de contribuir al desarrollo de métodos de control biológico. Se discuten las fluctuaciones vegetales y animales con el fin de determinar el daño cuantitativo a la planta, junto con algunas observaciones sobre la biología de los posibles agentes de control.
