Sažetak
The western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte, is the most important insect pest introduced into Europe in past 50 years. The infested area reached 284 500 km^2 with an economic population on 64 000 km^2 in 2002 in Europe. In Croatia WCR is present on 19, 000 km^2, on 250, 000 ha of corn with damage up to 80%. The population density of WCR for each year was higher than in previous year. The focus of the study was to determine if WCR adults over the population buildup period in Europe could be attracted to crops grown in rotation with corn for egg laying. The crop rotation trials were set up in Hungary in 2000 and in Croatia in 2001. The presence of WCR was assessed and quantified by using Pherocon AM traps and emergence cages. Soil and corn root samples were taken to determine WCR larval populations. It was determined that WCR females have the ability to lay eggs in rotated crops, although presently at low levels, and some larval feeding was noted in the following year's corn. WCR adults were trapped by Pherocon AM traps in non-corn plant stands (winter wheat or barley, sunflower and soybean), though in significantly lower numbers when compared to corn. Based on the study, there is a potential for WCR female egg laying in non-corn plant stands.
