Sažetak
The Western corn Roootworm-WCR (Diabrotica virgifera virgifera LeConte) infested Croatia in 1995 and in 1997 spread about 100 km west of the Yugoslav border. By use of 650 traps, the WCR was monitored during 1997 in 123 places. A total of 3906 beetles were caught, 97, 6% by pheromone traps. In comparasion to 1996, the population density increased three times in 1997. The density decreased significantly from the east to the west and from the south to the north of Croatia. In Tovarnik, near the Yugoslav border, the maximal daily density was 13 beetles per trap, while the density during the whole period of appearance was 3, 2 beetles per trap per day. The first beetle was caught on July 4th, and the last one on October 3rd. In spite some damage to the roots, there were no yield losses recorded in Croatia.
