Life cycle of the potato golden cyst nematode (Globodera rostochiensis) grown under climatic conditions in Belgrade [Serbia]

The life cycle of a population of the quarantine nematode Globodera rostochiensis on the root of susceptible potato variety, Desiree, originating from an infected field (CC Ljubovija no. 413) on the mountain of Jagodnja in the district of Mačva (Serbia), was studied under experimental conditions in Belgrade (Serbia) during 2002-2003. The golden cyst nematode completed one generation per year in the temperate climate of this region. In 2002, the life cycle lasted 29 days after the penetration of the second stage juveniles into the roots. An adverse effect of high soil temperatures above 25 deg C was observed in 2003, influencing the development of the nematode and making the life cycle last two months longer.
