Wireworms within the genus Agriotes (Coleoptera: Elateridae) can cause substantial damage to agricultural crops. The vertical movements of these pest insects in the soil make the timing of control measures a difficult task. The forecast model SIMAGRIO-W utilises soil temperature and moisture data to predict the migration of Agriotes wireworms to the upper soil layer. The model distinguishes between two risk levels: low risk (less than 30% of the wireworm population in the upper soil layer) and high risk (more than 30%), which are considered adequate for practical purposes. In this study, SIMAGRIO-W was tested on arable land in eastern Austria. At three sites in Traiskirchen (Lower Austria; site 1) and Bruck/Leitha (Lower Austria; sites 2 and 3), wireworm activities in the upper 15 cm of the soil were measured with wireworm bait traps from the middle of July until the end of October 2013. At sites 1 and 3, activity measurements were extended to spring 2014. In the last trapping period of 2013, control transects were installed at a distance of 10 m from the regular transects at sites 1, 2, and 4 (= control transect; Figure 2). The intention was to investigate whether permanent wireworm sampling had falsified the results by thinning out the wireworm populations at the regular transects. Over the entire investigation period, data loggers recorded soil moisture and temperature every 30 minutes in 15 cm and 80 cm soil depth at each site. Moisture and temperature sensors were installed at the beginning of the experiment in potholes, which were backfilled with soil after applying the measuring equipment. The measured values of soil temperature, soil moisture, and soil type were used to simulate the percentage of the Agriotes wireworm population in the top soil layer of each site by the use of SIMAGRIO-W. The daily calculated forecasts were averaged for each trapping period and afterwards compared with the measured wireworm activities.
