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