Ekspresowa Analiza Zagrożenia Agrofagiem: Nacobbus aberrans

N. abberrans has already been recorded in Europe, but is currently not found on the Old Continent. Natively it is found throughout the Americas. It is a polyphage, among its host plants are both wild and economically important species, including potato, sugar beet, tomato, bell pepper. In areas where it occurs it has been the cause of significant crop losses. The most likely route of entry into a PRA area is the importation of underground plant parts, such as ornamentals, potato tubers, and soil or substrate residues adjacent to the roots. The nematode's high resistance to low temperatures and periods of drought facilitates its survival in transport. In addition, the varying adaptability of individual N. abberrans populations increases the uncertainty of assessing whether the agrophage will be able to survive and colonize crops in Poland. Currently, however, there is a low probability of the nematode's survival and development in the country, although at the same time it should be emphasized that the lack of relevant experimental data significantly increases its uncertainty. Forecasted climate changes like milder winters may favor population maintenance. A general assessment of the risk caused by Nacobbus abberrans in Poland is estimated as low to medium.PL; pl; PDF; kwarantanna@iorpib.poznan.p
