ABSTRACT
Forest restoration is mainly based on plant-soil relationships and plant species with economic potential, but those between insects and other arthropods are also important to this reestablishment. The objective was to evaluate, during 24 months, the relationships between tending ants, Hemiptera phytophagous, predators and their distribution pattern (aggregated, random or uniform). The arthropods were sampled, stored and identified and their relationships and distribution patterns calculated with the BioDiversity-Pro software. The number of tending ants and phytophagous Hemiptera, Brachymyrmex sp. and Aethalion reticulatum, Cephalotes and Aleyrodidae were positively correlated. Tending ants were negatively correlated with Sternorrhyncha predators on A. auriculiformis saplings. The distribution of arthropods was aggregated, except for Teudis sp. and Cephalocoema sp., with a random pattern. The herbivores Stereoma anchoralis, Aethalion reticulatum and Tetragonisca angustula and the predators Brachymyrmex sp. and Dolichopodidae were the most abundant arthropods. The relationships between the arthropods studied on A. auriculiformis indicate that this plant, even introduced, is suitable for programs to recover degraded areas in the savannah.
A restauração florestal é baseada nas relações planta-solo e espécies vegetais com potencial econômico, mas aquelas entre insetos e outros artópodes são, também, importantes para esse processo. O objetivo foi avaliar as relações entre formigas, fitófagos Hemiptera e predadores e a distribuição (agregada, aleatória ou regular) de artrópodes, por 24 meses, em mudas de Acacia auriculiformis utilizadas na recuperação de áreas degradadas. Os artrópodes foram amostrados, armazenados e identificados e suas relações e padrões de distribuição calculados com o software BioDiversity-Pro. Os números de formigas cuidadoras se correlacionaram, positivamente, com os dos Hemiptera fitófagos Aethalion reticulatum, Brachymyrmex sp. e Cephalotes e Aleyrodidae. Insetos cuidadores de Hemiptera foram, negativamente, correlacionados com predadores Sternorrhyncha em plantas de A. auriculiformis. A distribuição dos artrópodes foi agregada, exceto Teudis sp. e Cephalocoema sp., com padrão aleatório. Aethalion reticulatum, Stereoma anchoralis e Tetragonisca angustula foram os herbívoros e Brachymyrmex sp. e Dolichopodidae os predadores mais abundantes. As relações entre os artrópodes estudados em A. auriculiformis indicam que esta planta, mesmo introduzida, é adequada para programas de recuperação de áreas degradadas no cerrado.
