RESUMEN. Los modelos dinámicos a nivel de rodal son ampliamente usados en el ámbito forestal. Para su ajuste se emplean datos empíricos que se integran en un conjunto de ecuaciones que describen las relaciones entre diferentes variables. Las metodologías clásicas para desarrollar ecuaciones de transición invariantes con respecto al intervalo de simulación (path invariance) e invariantes respecto a la edad de referencia empleadas son algebraic difference approach (ADA) y generalized
algebraic difference approach (GADA). El objetivo de este trabajo fue desarrollar un modelo dinámico de rodal para Eucalyptus globulus, empleando ecuaciones de transición para área basal, altura media dominante y mortalidad, utilizando enfoque de variables dummy. Los datos utilizados provienen de 168 parcelas permanentes. Las ecuaciones evaluadas individualmente fueron luego ajustadas simultáneamente mediante seemingly unrelated regression (SUR). En base al análisis de bondad de
ajuste y de la capacidad predictiva, se seleccionó el modelo propuesto por Korf, modificado por Cieszewski (2004), para la altura media dominante; el modelo de Levakovic (Zeide, 1993), para el área basal y el modelo de Pienaar y Shiver (1981) para la mortalidad. El modelo de simulación desarrollado es más flexible y permite levantar algunas de las limitantes del modelo utilizado anteriormente. Su integración a sistemas de apoyo a la toma de decisiones constituirá una herramienta de
gran utilidad para la planificación y toma de decisiones en el sector forestal. SUMMARY. Stand level dynamic models are widely used in forestry.

The aim of this study was to develop a dynamic model for Eucalyptus globulus stand using transition equations for basal area, dominant average height and mortality, using tle dummy variables approach. The data used are from 168 permanent plots. The equations evaluated individually were then adjusted simultaneously by seemingly unrelated regression (SUR). Based on the analysis of goodness of fit and predictive ability, the model proposed by Korf, as amended by Cieszewski (2004), for the dominant average height was selected; Levakovic model (Zeide, 1993) for the basal area and the model Pienaar and Shiver (1981) for mortality. The simulation model developed is more flexible and can lift some of the limitations of the model used previously. Its integration into a decision support system (DSS), constitute a useful tool for planning and decision making in the forestry sector. MenosRESUMEN.

Abstract:
Cacopsylla bidens (?ulc, 1907) is one of the key pests of pear. Its management has been based on broad-spectrum insecticides, which cause the appearance of resistance and the disappearance of the population of the natural controllers. This fact makes it necessary to find alternative strategies to control this pest, and the biological control can be a sustainable solution in the long term. The aim of this work was to evaluate the effect of the ground cover management on psyllid populations and its natural enemies and register the natural enemies' families present in Uruguay. Sampling was conducted in southern Uruguay, between 2013 and 2015. Two treatments were evaluated: regular cut of spontaneous vegetation of interrow with herbicide in the row, and uncut vegetation of the interrow with no herbicide. To determine the presence of beneficial arthropods, a garden vacuum cleaner was used on a weekly basis. Psylla catches were significantly lower in the uncut treatment compared to the other treatment. Natural enemies, on the contrary, were higher in the uncut treatment. The pool of natural enemies found was present throughout the year and was composed of predators belonging to the families Anthocoridae, Miridae, Chrysopidae, Coccinellidae, Syrphidae and the order Aranae, as well as parasitoids belonging to the family Encyrtidae. These results allow us to conclude that treatment without management of the ground cover generates a condition beneficial for the increase of populations of natural enemies, probably due to better feeding and multiplication conditions. This beneficial fauna seems to control psyllid populations providing an alternative for management of pear psyllid, reducing the use of insecticides in the orchards.
