Two species of carabid beetles: Bembidion properans Steph. and Pterostichus cupreus L. were the most often captured in pitfall traps in the spring period on plots with various cultivars of annual legumes. The highest density of P. cupreus population in the field with annual legumes was observed in May, in the feeding and egg laying period of the pea weevil Sitona lineatus L. (Col., Curculionidae) - the main legume pest. In June the most frequent carabid was B. properans; the small beetles destroy the eggs or young larvae of Sitona lineatus. No effect of using Steinernema carpocapsae nematodes to infect nontarget carabid species was found in case of different densities of invasive larvae on the soil surface in traps although the mortality of captured ground beetles was high. The length of life of Carabidae collected from traps with nematodes were not significantly lower in comparison with the control group
