Abstract The potato cyst nematodes (PCN) Globodera rostochiensis (Stone) and Globodera pallida (Woll) are economically important parasites of potatoes and other members of the Solanaceae family. They are listed in the EU Plant Health Directive 2000/29/EC and are regulated by the European PCN Directive (2007/33/EC). In the UK, management of PCN relies on long rotations, nematicides and resistant cultivars, though for G. pallida there are few cultivars available with high levels of resistance. Climatic conditions differ around the UK and there is a trend towards increasing temperatures and changes in rain fall associated with climate change. The aim of this study was to investigate the relationship between soil temperatures and the PCN life cycle and population multiplication in order to understand the risk to potato crops from PCN in relation to soil temperatures and to support the development of the Potato Council`s PCN management model. In this report the initial part of the PCN life cycle, hatching, was examined for both species over a range of temperatures and the responses are then considered in relation to actual soil temperatures that were recorded immediately after the potato crop was planted.
