Morphology of two new Globodera rostochiensis populations from Serbia

Abstract

In concordance with phytosanitary regulations and the Program of continuous monitoring of quarantine and economically harmful nematodes that are intensively conducted every year, the presence of these organisms is determined in the territory of the Republic of Serbia and in the samples of plant material. Globodera pallida and G.rostochiensis are the most important parasites of potato in our country and their presence is monitored since 2005 and 2000 respectively. Morphology, i.e. examination of morphological characters of different populations of potato cyst nematodes determines their mutual similarities (differences) within species, between species and the similarity with the type populations. This paper presents the morphological descriptions of cysts and second stage larvae of two populations of G.rostochiensis found in localities Rujevac and Tabanovici in 2012.

U skladu sa Programom stalnog praćenja karantinskih i ekonomski štetnih nematoda koji se intenzivno sprovodi svake godine kao i fitosanitarnom regulativom, utvrđuje se prisustvo ovih organizama na teritoriji Republike Srbije i u uzorcima biljnog materijala. Globodera pallida i G. rostochiensis su najznačajniji paraziti krompira kod nas a njihovo prisustvo se prati od 2005. odnosno 2000. god. Morfologija odnosno ispitivanje morfoloških karakteristika različitih populacija cistolikih nematoda krompira daje podatke o njihovoj međusobnoj sličnosti (razlikama) unutar vrsta, između vrsta i sličnost sa tipskim populacijama. U radu su dati morfološki opisi cisti i larvi drugog stepena dve populacije G. rostochiensis pronadjene na lokalitetima Rujevac i Tabanovići u 2012. godini.
