| ABSTRACT This study aimed to evaluate the development of soybean as a function of traffic levels of an agricultural tractor equipped with radial tires in two collection areas. The experiment was conducted in an area located at the State University of Maringá, Campus of Umuarama-PR, Brazil, in a soil classified as Red Oxisol with sandy texture. The experiment was set in a 5 x 2 factorial arrangement, with five levels of traffic on the same track (T1 = 1, T2 = 6, T3 = 11, T4 = 16 and T5 = 21 tractor passes), two collection areas (A1 = on the track and A2 = off the track) and four replicates. Soil physical parameters and characteristics of the soybean plants were evaluated. Soybean yield on the track did not show significant difference up to 6 passes. It was... |

| ABSTRACT This paper records the first report of Megastigmus transvaalensis Hussey (Hymenoptera: Torymidae) in Brazilian peppertree, Schinus terebinthifolius Raddi (Anacardiaceae) drupes in Sorocaba, state of São Paulo, Brazil. This wasp is an invasive species and was found damaging S. terebinthifolius drupes in urban areas (35.0±15.8%), natural forests (21.5±10.2%) and restoration areas (15.8±8.4%). The bio-ecology and damage caused by M. transvaalensis in the S. terebinthifolius drupes warrants further study focused upon the management of this phytophagous wasp. Megastigmus transvaalensis has a potential to be disseminated throughout Brazil and is posing a threat to the natural regeneration of S. terebinthifolius in the native forests and restoration... |
