RESUMO
Com o objetivo de verificar a ocorrência de insetos da parte aérea na cultura da soja convencional e geneticamente modificada resistente a glyphosate, realizou-se este trabalho durante a safra agrícola 2004/05, em Cruz Alta, RS, na área experimental da Fundação Centro de Experimentação e Pesquisa (FUNDACEP). A semeadura foi realizada no dia 26/11/2004, no delineamento experimental de blocos ao acaso com parcelas subdivididas e com quatro repetições, em esquema fatorial 2 x 3. O fator A correspondeu à cultivar "CD 214 RR" resistente a glyphosate e à "CD 201" convencional e o fator B correspondeu ao sistema de manejo das plantas daninhas (sem controle, controle mecânico e controle químico tradicional) e com um tratamento adicional (controle químico com glyphosate na cultivar "CD 214 RR"). A utilização da soja geneticamente modificada resistente a glyphosate e a aplicação do herbicida glyphosate alteraram a ocorrência de algumas espécies de insetos-praga e inimigos naturais na parte aérea da soja.
ABSTRACT
The experiment was carried out during the crop season 2004/05, in Cruz Alta, RS, Brazil at Fundação Centro de Experimentação e Pesquisa (FUNDACEP) experimental area. The objective was to study the occurrence of insects in conventional and genetically modified herbicide-tolerant soybean. The seeding was done in November, 2004. The experimental design was randomized blocks and factorial scheme. The factor A was represented by the varieties 'CD 214 RR' (glyphosate-tolerant) and 'CD 201' (conventional). The factor B was composed by weed management systems, were b1- without weed control, b2- mechanical control and b3- chemical control with conventional herbicides. An additional treatment was used, where glyphosate application on 'CD 214 RR' was done. Soybean genetically modified herbicide-tolerant and glyphosate application had effects on some pests and beneficial insects in soybean.
