SUMMARY
The potato cyst nematodes Globodera rostochiensis and Globodera pallida are among the
most dangerous potato pests in the world and this is why these species are included in the
list of quarantine organisms in many countries. During the last decade, by regular official
program for control of fields for production of seed potato in Serbia, the foci of both species
were discovered and designated as quarantine areas. In order to prevent their spread, an
official surveillance on the presence of these species in the ware potato growing areas has
been carried out since 2009. This paper presents the results of the inventory of potato cyst
nematodes in ware potato fields in the period between 2009 and 2012 in the framework
of implementation of the program of the annual plant health protection measures of the
Ministry of Agriculture, Forestry and Water Management of the Republic of Serbia. In all
cases, only Globodera rostochiensis was found in already infected, quarantine areas of western
Serbia in districts of Mačva, Zlatibor and Moravica. The presence of G. rostochiensis
was detected in 8.87 % soil samples with population densities ranging from 40 to 8040
eggs and second juvenile stages in 100 cm 3 of soil. The highest percentage of infected soil
samples was registered in district of Mačva while the highest population density was found
in district of Zlatibor.
