Surveys on nematodes of potatoes in Saudi Arabia

A survey has been conducted in Saudi Arabia from 1989 to 1991, in the six major potato-producing regions. The following genera, with their respective frequency, were found: Aphelenchus (40 %), Ditylenchus (28 %), Tylenchorhynchus (20 %), Meloidogyne (19 %), Aphelenchoides (10ÿ%), Tylenchus (9 %), Subanguina (6 %), Trichodorus (5 %), Pratylenchus and Helicotylenchus (2 %), Macroposthonia (0.7ÿ%), Pratylenchus and Cacopaurus (0.2 %). In Saudi potato fields, the main problems are due to
Meloidogyne spp. (mainly M. javanica), Tylenchorhynchus spp. and Ditylenchus spp (mainly D. destructor - EPPO A2 quarantine pest). This is the first report of D. destructor in Saudia Arabia known to the EPPO Secretariat.
