In order to study the impact of transgenic maize on beneficial arthropods, two varieties of maize Bt (Compa CB and Elgina) and the normal ones (Dracma and Cecília) were sown. The trials were carried out, in Escaroupim, Ribatejo, from 2002 to 2004. The surveys were done by using a cordless hand vacuum machine, every 15 days, during the growing season. The results showed no significant differences between arthropods caught in maize Bt and the normal one. The beneficials with the highest numbers caught during the three years were Anthocoridae, Hymenoptera and Aranea were the first, second and third most representative groups of beneficial arthropods during the three years.
