• Plant-parasitic nematodes are important pests in world agriculture
  • Proper identification is a prerequistie for plant protection as well as scientific research
  • Pests of the genera Longidorus and Paralongidorus harm plants directly and as vectors of nepoviruses
  • This paper presents a key enabling identification of species from these genera occuring in Poland
Plant parasites of the genera Longidorus Micoletzky, 1922 and Paralongidorus Siddiqi, Hooper and Khan, 1963 comprise a group of plant root ectoparasites, some of which are known as pests of economic importance. Their importance is further augmented by the fact that several species are known to be vectors of nepoviruses. To date 16 species from the genus Longidorus and two from Paralongidorus have been recorded in Poland. Despite their economic importance in agriculture currently there is no regional key for species identification. This paper presents such a key. The key has many illustrations and is based mainly on traits which are easily observable even by less experienced users. Thus, it should provide a useful tool for both scientists and specialists working in the field of plant protec- tion, soil ecology and zoology as well as for teaching purposes.
I would like to thank colleagues dr. Aneta Chałańska, dr. Andrzej Skwiercz and dr. Grażyna Winiszewska for their helpful comments on previous versions of the key.
