Abstract

With the settle of western corn rootworm (Diabrotica virgifera virgifera LeConte) (from 1995), the spectrum of pests with potential damage in Hungary increased. The pest was followed by trapping (with sex-pheromone and colour traps). In 2000 the pest was found in whole Hungary (except Győr-Moson-Sopron, Vas and Szabolcs-Szatmár-Bereg county), in extremely fl uctuating number (1-700 pest/trap). In the southern region for maize production (Csongrád, Békés, Bács-Kiskun, Baranya, Tolna county), where the pest was found fi rst, the number of it increased in various centres. Based on these data, we carried out insecticide experiment.
