Plano de amostragem de Acromyrmex spp. (Hymenoptera: Formicidae) em áreas de pré-plantio de Pinus spp

A study was conducted to elaborate a sampling plan to leaf cutting ants in forest pre-planting areas, at Bosques del Plata company, located in Santo Tome, Corrientes province, Argentine. The research had as object of study the spatial distribution of Acromyrmex nests in Pinus spp. pre-planting areas to determine the adequate plots size and to estimate the sampling intensity to this genus of ants. It was concluded that the Acromyrmex spp. nests spatial distribution in Corrientes-Argentine, adjusts to the randomized model, the adequate plot size to sample the nests density (hole. ha-1) is 700m2 (10x70m) and the adequate sampling intensity is 10.5% for a predicted error of 24%.
