Alien arthropod pests of Hungarian arable plants.

Abstract

The arable farming is a purposeful element of Hungarian agriculture, which is contribute to the Hungarian total GDP with 3.7%. The settling of new, alien species was triggered by the climatic trends in the last period and the increasing urban abilities. These facts can consent to the enhancement of production uncertainty. The aim of this study was to denote the proportion of alien species of main arable plants, so the changing of the pest spectrums and the pest management consequences can be easier estimated. The study pointed out the determinative proportion (14.11%) of alien pests in field crops. The most alien pests appeared in cultivated plants originating from American continent - such as potato, sunflower and maize - in Hungary. The most economic important arthropod pests (Diabrotica v.virgifera LeConte, Helicoverpa armigera Hübner, Globodera rostochiensis Wollenweber, Phthorimaea operculella Zeller) were introduced in the Hungarian maize and potato cultivation in the last century.
