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

Abstract

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, was studied under experimental conditions in Belgrade in 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 °C was observed in 2003, influencing the development of the nematode and making the life cycle last two months longer

THE EFFECT OF TEMPERATURE, POTATO VARIETIES, AND THE ORIGIN OF CYST ON THE REPRODUCTIVE BIOLOGY OF Globodera rostochiensis (PENGARUH SUHU, VARIETAS KENTANG, DAN ASAL SISTA TERHADAP BIOLOGI REPRODUKSI Globodera rostochiensis)

“…In Southern Italy, second stage larva of G. rostochiensis decreased drastically invasion into the roots at a temperature of more than 25ºC and 95% reduction occurred in a population of G. rostochiensis at temperature more than 30ºC (Bacic et al, 2011;Bridge & Starr, 2010;Turner & Evans, 1998). This suggests that increasing temperature due to external factors may be coped by the adaptability of this nematode.…”
