SUMMARY In laboratory tests cysts of 12 isolates of potato cyst eelworms Heterodera rostochiensis Woll. and H. pallida Stone reared on Lycopersicon peruvianum B6001 (which is resistant to H. rostochiensis ) and L. esculentum (tomato)‘Ailsa Craig’ were subjected to hatching stimulation in potato‐root diffusate. Larval emergence from isolates in which H. pallida predominated was more rapid than that from isolates in which H. rostochiensis predominated. Possible reasons for this difference are discussed.
