Abstract:
Seventeen plant parasitic nematode species were recovered from soybean fields in Menia, Assiut and Sohag Governorates, Egypt. The species Helicotylenchus pseudorobustus, Longidorus pisi, Pratylenchoides ritteri, P. variabilis, Rotylenchulus parvus and Tylenchorhynchus annulatus are new records for the Egyptian nematode fauna. Merlinius brevidens was found in relatively high percentage of occurrence, while Pratylenchus zeae was found in relatively high population densities. Meloidogyne javanica, M. incognita, Pratylenchus zeae, H. pseudorobustus, R. parvus, Hoplolaimus seinhorsti, Heterodera sp. and Xiphinema sp. may also be of great importance in the fields of soybean in Upper-Egypt. M. javanica, M. incognita were detected with higher population density in sandy soil than in the sandy loam and loamy soils. Pratylenchus zeae and M. brevidens were noted with relatively high population density in three soil types especially in sandy loam. H. pseudorobustus was found in relatively high population density in loamy soils. High numbers of R. parvus were found in sandy loam soil.
