26. Chemical and Spectroscopic Characteristics of Anthrosol (Amazonian Dark Earth) and Surrounding Soil from the Brazilian Amazon Forest: Evaluation of Mineral and Organic Matter Content by Depth
The chemical and spectroscopic characteristics of soil organic matter (SOM) isolated from Amazonian dark earth (ADE) and surrounding soil (SR) were evaluated according to the soil depth. The results showed opposite trends for the soils. While ADE featured SOM with a greater aromatic condensation degree and greater hydrophobicity in the top layer, the SR show

32. First record of Anastrepha bahiensis Lima (Diptera: Tephritidae) infesting fruits of Averrhoa carambola L. in the eastern Amazon, Brazil
ABSTRACT We report for the first time field infestation under natural conditions by Anastrepha bahiensis on star fruit (Averrhoa carambola L., Oxalidaceae) in the state of Pará, Eastern Amazon, Brazil. This report reinforces the importance of field infestation studies on fruit flies in the Brazilian Amazon.
