Avaliação da comunidade de artrópodes de solo em milho geneticamente modificado Mon 810 e Mon 89034

Abstract

The entomofauna of soil on genetically modified maize genotypes Yieldgard® and VTPRO® (MON 810 e MON 89034) has been assessed through a study conducted at the field. Have been assessed the indexes of fauna of insects collected during the off-season period of 2011. The collections were carried out by pitfall traps, being collected during the sample period a total of 5335 specimens, distributed into 12 orders, 28 families and 47 species. The main orders were collected: Orthoptera, Coleoptera, Hemiptera and Hymenoptera. The most frequent species were: Gryllus assimilis (Fabricius), Nabis sp., Calosoma granulatum (Perty), Formicidae sp1 and Dichelops sp. The indices of richness, diversity and Evenness were low, but considered normal for the agricultural environment. The similarity of species composition between hybrids evaluated stayed above 83%. The quantity of specimens in each functional group was similar among the three hybrids, indicating that there is no effect of transgenic maize when compared with the conventional. In general the two transgenic hybrids evaluated, did not submit effect on insect community associated with culture, when compared with its conventional hybrid.
