A preliminary report on the plant-parasitic nematodes in Jordan

Abstract

Little is known about the plant-parasitic nematode fauna of Jordan. Abu-Gharbieh (1975), Abu-Gharbieh and Hammou (1972), Abu-Gharbieh et al. (1978), Anon. (1970, 1971) and Qasem (1970) reported the presence of root-knot nematodes (Meloidogyne spp.) in the irrigated lowlands: also, both Anguina tritici (Steinbuch) Chitw. and Merlinius rugosus (Siddiqi) Siddiqi were reported to occur in the country by Qasem (1970) and Hashim (1979) respectively. A list of nematode genera prevalent in Jordan has been published, but the only species referred to was M. incognita (Kofoid et White) Chitw. (Anon., 1970). In view of this limited knowledge, and as a preliminary step in determining where the major potential nematode problems lie, a list of the nematode species recently found associated with certain crops in Jordan is presented herein.
