Research paper. Distribution, Abundance and Dominance of Three Brachinus Species (Coleoptera: Carabidae) in Seven Agricultural Crops in Romania, within the Period 1977–2010

The present paper is a relevant synthesis of collecting original data on the occurrence, quantitative representation and autecological data of three species of the genus Brachinus: B. crepitans Linnaeus, 1758, B. psophia Audinet-Serville, 1828 and B. explodens Duftschmid, 1812 from seven agricultural crops during 19 growing seasons 1977-2010 (wheat, sugar beet, apple orchards, sunflower, maize, potatoes, vineyards). The beetles were pitfall-trapped using predominantly 12 Barber pitfalls in each site, protected against precipitation. 945 specimens of Brachinus crepitans, 431 specimens of B. psophia and 175 specimens of B. explodens were collected.
