Incidence of the Potato Cyst Nematode, Globodera rostochiensis (Wollenweber 1924, Skarbilovich 1959, Behrens 1975) in Northeast Egypt

Abstract

A survey was carried out in the autumn season of 2025 in the area cultivated with potatoes in El- Kassasein, Ismailia governorate, northeast, Egypt. Soil and root samples were collected from the rhizosphere of potatoes after different days from potato emergence for the detection of potato cyst nematode (PCN), Globodera spp. The results showed the occurrence of PCN on potato (Solanum
tuberosum L.) at all three times of sampling. Morphometrics and morphology of both cysts and the second-stage juveniles (J2) were consistent with the taxonomic characteristics of Globodera rostochiensis. To our knowledge, The G. rostochiensis was previously detected in Egypt, but this is the first detection in Ismailia Governorate, located in the northeast of Egypt.
