Two decades of invasive western corn rootworm surveillance in Croatia

The thorough knowledge of the western corn rootworm invasion in Croatia is unique in Europe, as no other European nation has demonstrated such a detailed and complete understanding of an invasive insect till now. After the beetle’s first detection in Serbia in 1992, Croatia have established a national monitoring program. For more than two decades WCR adult population abundance and variability was monitored. With traditional density monitoring, more recent genetic monitoring, and the newest morphometric monitoring of WCR populations, Croatia possesses a great deal of knowledge about the beetle’s invasion process over time and space. The combined use of traditional monitoring (attractant cards), which can be effectively used to predict population abundance, and modern monitoring procedures, such as population genetics and geometric morphometrics, has been effectively used to estimate interand intra-population variation. The combined application of traditional and modern monitoring techniques will enable more efficient surveillance, reporting and forecasting of WCR across Europe.
