O principal objetivo do estudo foi o de inventariar a fauna de formigas do Centro de Endeminmo Pernambuco, mais especificamente de três sítios (Reserva Ecológica de Gurjaú e RPPN Frei Caneca, em Pernambuco, e Usina Serra Grande, em Alagoas) pertencentes a duas áreas localizadas no sual do estado de Pernambuco e norte de Alagoas, a Região Gurjaú/Camaçari e o Complexo Catende, nestas áres se encontram os maiores remanescentes de Floresta Atlântica deste centro de endemismo, sendo consideradas prioritárias para a conservação. |

Soybean sudden death syndrome (SDS), caused by Fusarium solani f. sp. glycines, is found in more than 2.0 million hectares of soybean fields in Brazil. Identified for the first time during the 1981/82 crop season, in São Gotardo, Minas Gerais; it had already spread to 99 counties in Central and South Brazil by the 1999/2000 crop season, causing an estimated yield loss of US$ 53 million. Since no efficient control measure is yet available , it has been carried out through resistant cultivars. One of the difficulties in selecting resistant cultivars lies on the lack of a reliable source of resistance and of a screening method to distinguish the reactions among cultivars. The objective of this study was to define a criterium for differentiating soybean cultivars reaction to SDS and to find sources of resistance to the disease, based on leaf symptoms. The study included eight soybean cultivars in four replication and were carried out in a greenhouse in two experiments. Plants were inoculated by the colonized toothpick method and assessed 21 days after inoculation , using five different assessment criteria. Results showed that during the determination of the AP % (affected plants percentile ), which revealed the different reactions to SDS among soybean cultivars, the levels of chlorosis were not significantly different from those which took into consideration the incidence of leaf chlorosis or necrosis, regardless of the severity of leaf symptoms. The %AP and the scoring method using a scale of 1 to 5 were the best procedures to assess the reaction of soybean cultivars to SDS through leaf symptoms. Cultivar FT Estrela was used as a highly susceptible standard SDS (%AP = 96.32%). Genotypes PI 567734, PI 520733 and MG/BR 46 (Conquista) were the most resistant to SDS with AP % of 30.79%, 31.30% and 35.34%, respectively. They could be used as a source of SDS resistance in crosses in breeding programs.
