Corn agricultural agroecosystems is considered unstable ecosystems, with specific interdependencies between differentfood chains that natural factors play a role. A large number of insects are living in the maize agroecosystem, being aspecies community and each species has a particular place in the food chains. If a lot of studies were done, in Romaniaabout biology, ecology and control of corn insect pest, there are little knowledge aboutepigeal fauna captured fauna inpitfall traps (Barber).Experiences from 2011-2012 had the main objective to observe the potential impact of GMOmaizeon the epigeal fauna. (39.7%), Pterostichus vulgaris L. 1758 = [P. (Morphnosoma) melanarius Illiger 1798](32.5%), Carabus coriaceus L.1758 (18.3%), Pterostichus melas Creutzer 1799 (5.3%), Pseudoophonus (Harpalus)rufipes De Geer 1774 (2.2%) and Pterostichus cupreus L. 1758 (2.0%). Cultivation of genetically modified corn, has noinfluence on epigeal fauna, field cultivated with this type of plants has no observed differences regarding faunabiodiversity. Data obtained regarding resemblance of whole insect fauna from those cultural variant, taken intoconsideration, represented by value of Sorensen index, confirm idea that corn hybrids containing transformation eventhas no evident influence on epigeal carabid insect fauna from corn field.
