Descripción
Leaf- cutting ants are the most economically important pest of plantation forests in the Neotropics. These social insects can defoliate whole trees, reducing their growth ability and occasionally causing tree mortality. Control of leaf- cutting ants in plantations is mainly carried out by using insecticides such as sulfluramid or fipronil. Foresters that adhere to voluntary sustainability certification systems are requested to implement integrated pest management programmes that reduce the use of insecticides. However, this approach is much delayed since it requires a better understanding of ant ecology, including quantitative data on the long- term impact that leaf- cutting ants have on tree plantations. In this study, we show, for the first time, the results on the long- term impact of Atta sexdens L. on a Pinus taeda L. plantation in NE Argentina. The annual growth in diameter, height, volume and mortality of P. taeda trees in two 11 ha stands were evaluated up to the middle of the harvest cycle (i.e. 6 years). One of the stands had no control of A. sexdens nests, and in the other stand, all ant nests were removed (total control). After six years since planting, P. taeda trees show significant reductions in total height (19%), diameter at breast height (4.4%) and wood volume (21%) in sites with A. sexdens present. Moreover, tree mortality reached 31.2% when ants were present. Forest managers could use these results to improve their integrated management programmes, by better adjusting their economic damage threshold parameters.
