Identificación de hormigas cortadoras de hojas de la provincia de Misiones por herramientas morfológicas y moleculares

Abstract

Las hormigas cortadoras de hojas se encuentran entre los principales insectos plaga de las plantaciones forestales en la provincia de Misiones. En la identificación de los insectos plaga tradicionalmente se emplean caracteres morfológicos. Sin embargo, numerosos grupos de insectos son indistinguibles o presentan diferencias muy sutiles entre ellos. Incluso aunque la taxonomía sea un área compleja y en continuo cambio, numerosas claves y bases de datos de identificación están desactualizados dificultando una identificación taxonómica adecuada. En este contexto los datos moleculares se pueden emplear como una herramienta auxiliar a los datos morfológicos. Los objetivos de este trabajo fueron identificar morfológica y molecularmente hormigas cortadoras de hojas que atacan a plantaciones forestales de la provincia de Misiones. Fue posible extraer ADN de buena calidad de dos especies de hormigas cortadoras de hojas de los géneros Atta y Acromyrmex. Y estos datos fueron empleados como herramienta complementaria en la identificación taxonómica de estas hormigas cortadoras de hojas.

The objective of this work was to evaluate the white algarrobo (Prosopis alba) development in forestations under different soil conditions in the Chaco Province by means of analyzing dominant height variation related to soil variations. The work was carried out by sampling 29 plots in plantations with individuals between 15 and 19 years old. The measured parameters in soil were: roots effective depth, drainage and relief. The horizons sequence for each soil profile was determined and in them thickness, texture, electrical conductivity, hydrogen potential were evaluated. The dominant height was determined in the sampled trees.The statistical analysis showed significant differences for the effective root depth and drainage parameters in relation with the dominant height measured in trees. As the main result, we conclude that the dominant individuals had better growth conditions in soils that presented more than 50 cm of effective root depth and good drainage conditions.
