Situation of Diabrotica virgifera in Poland in 2006
In Poland, Diabrotica virgifera (Coleoptera: Chrysomelidae – EPPO A2 List) was first caught in 2005 in the south-eastern part of the country (see EPPO RS 2005/083) at three locations: Dukla (1 specimen trapped near an international road leading to the Slovak border), Łąka and Jasionka (5 and 3 specimens trapped in maize fields near the airport in Rzeszów-Jasionka, respectively). In 2006, the monitoring programme continued. In total, 3,247 traps were placed at 1,526 locations. The first beetles were caught on 2006-07-24 in Pilszcz (voivoidship opolskie, near the Polish-Czech border). From July to the middle of October, a total of 17,171 beetles were caught on 428 traps (mostly pheromone traps), at 55 locations in 8 voivodships of the south and south-east parts of Poland. The results were as follows for each voivodship: podkarpackie (14,516 beetles), małopolskie (1,213), lubelskie (693), śląskie (313), świętokrzyskie (304), opolskie (128), dolnośląskie (3), mazowieckie (1). As a result of these findings, 88 focus and safety zones were demarcated and subjected to the following phytosanitary measures: prohibition to grow maize in monoculture, compulsory removal of volunteer maize plants, compulsory treatments against D. virgifera, prohibition to harvest before the end of the D. virgifera flying/activity period, prohibition to move soil and growing media from maize fields, compulsory cleaning of machinery. Monitoring activities will continue in 2007.
The situation of Diabrotica virgifera in Poland can be described as follows: Present, found in 8 voivodships in the south and south-east, under official control.
