The objective of this work was to list potential candidate bee species for environmental risk assessment (ERA) of genetically modified (GM) cotton and to identify the most suited bee species for this task, according to their abundance and geographical distribution. Field inventories of bee on cotton flowers were performed in the states of Bahia and Mato Grosso, and in Distrito Federal, Brazil. During a 344 hour sampling, 3,470 bees from 74 species were recovered, at eight sites. Apis mellifera dominated the bee assemblages at all sites. Sampling at two sites that received no insecticide application was sufficient to identify the three most common and geographically widespread wild species: Paratrigona lineata, Melissoptila cnecomola, and Trigona spinipes,... |

O parasitóide Aphidius colemani Viereck, 1912 apresenta alta mortalidade em temperaturas constantes superiores a 25°C. Provavelmente esta é a causa do insucesso no controle biológico de Aphis gossypii Glover, 1877 com o uso de A. colemani em temperaturas elevadas em casas de vegetação. Este trabalho teve como objetivo avaliar a resposta a diferentes temperaturas de indivíduos de A. colemani, originários de diferentes regiões climáticas do estado de Minas Gerais. Indivíduos de A. colemani foram coletados nos municípios de Juramento, Lavras e São Gotardo, e criados em laboratório por três gerações em A. gossypii em plantas de pepino, em sala climatizada (22±2°C, 70±10 UR e 12h de fotofase). Uma fêmea de A. colemani, acasalada e com 24-48h de vida, foi... |

The objective of this research was to determine, in field conditions, the minimal of phosphine effective dose for the cashew root borer control. Three experiments were set up at three different periods: August, October and November, 1994, to control the cashew root borer, Marshallius bondari Rosado-Neto (Coleoptera: Curculionidae), in Piaui State, Brazil. One, two, three and six phosphine tablets of three gram each, per plant were tested. In the August essay, phosphine was inefficient to control the borer. In the October essay, control was achieved using as little as 2 tablets per plant and in November with one tablet per plant to control the adult borers in the soil. Higher efficiency was achieved when treatment was applied far away from the last rain, in... |
