Diabrotica VirgiferaLe Conte in Poland in 2005-2007 and Regulations in the Control of the Pest in 2008Diabrotica virgiferaLe Conte has been present in Poland since 2005. The range of its distribution increased in 2006 and 2007.D. virgiferais known from areas of nine voivodeships in Southern and partially Central Poland. Current control strategy is based on containment measures to limit the spread of the pest from regions where it has occurred. This strategy includes the application of specific phytosanitary measures in defined parts of the country.

Ceratitis capitata (Wiedemann), the Mediterranean fruit fly or medfly, is one of the world's most serious threats to fresh fruits. It is highly polyphagous (recorded from over 300 hosts) and capable of adapting to a wide range of climates. This pest has spread to the EPPO region and is mainly present in the southern part, damaging Citrus and Prunus. In Northern and Central Europe records refer to interceptions or short‐lived adventive populations only. Sustainable programs for surveillance, spread assessment using models and control strategies for pests such as C. capitata represent a major plant health challenge for all countries in Europe. This article includes a review of pest distribution and monitoring techniques in 11 countries of the EPPO region. This work compiles information that was crucial for a better understanding of pest occurrence and contributes to identifying areas susceptible to potential invasion and establishment. The key outputs and results obtained in the Euphresco project included knowledge transfer about early detection tools and methods used in different countries for pest monitoring. A MaxEnt software model resulted in risk maps for C. capitata in different climatic regions. This is an important tool to help decision making and to develop actions against this pest in the different partner countries.

SummaryThe European corn borer (Ostrinia nubilalis Hbn.) has been reported in Poland since the 1850s, and has been causing damage in maize fields (Zea mays L.) since the 1950s. Initially, this pest was recorded only in the south-western part of Poland, but it spread to other regions as the cultivation of maize became more popular. The studies carried out in 2009-2012 demonstrated that the O. nubilalis larvae were found in all 16 provinces of Poland, causing damage to maize plants in 213-246 counties (out of all 380, i.e. 56.0-64.7%). Key words: Ostrinia nubilalis; Poland; occurrence; maize StreszczenieOmacnica prosowianka (Ostrinia nubilalis Hbn.) występuje na obszarze Polski od połowy XIX wieku, natomiast plantacje kukurydzy (Zea mays L.) uszkadza od lat 50. XX wieku. Początkowo szkodnik występował na kukurydzy jedynie w południowo-zachodniej części kraju, jednak wraz z rosnącym areałem uprawy tej rośliny rozprzestrzenił się na pozostałe regiony. Na podstawie badań wykonan ych w latach 2009-2012, wykazano że omacnica prosowianka występowała we wszystkich 16 województwach w Polsce uszkadzając rośliny kukurydzy na obszarze 213-246 powiatów (na 380 istniejących), co stanowiło 56,0-64,7% wszystkich powiatów wyodrębnionych w kraju.
