Two hundred soil samples from the A(p) horizon of a reed canarygrass field overlaying several different but related soils in northern Minnesota were analyzed for plant-parasitic nematodes and 22 edaphic factors. Pratylenchus penetrans was the predominant nematode taxon. Others were Aglenchus agricola, Tylenchorhynchus spp., Heterodera trifolii, Paratylenchus spp., Tylenchus maius, and Criconeme...

Sixty rhizosphere soil samples of apple seedlings and rootstock were collected from six nurseries of Khuzdar and Kalat districts of Balochistan. Six different plant nematodes were found associated with the seedlings and rootstock. The most predominant nematode was Xiphinema americanum, whereas the nematode found from a single locality was Tylenchus butteus. A matrix of similarities with respect...

during a nematological survey, nineteen known species of plant-parasitic nematodes belonging to the family tylenchidae (tylenchomorpha: tylenchoidea) were collected and identified from different localities of west azerbayjan and kermanshah provinces, iran. among them two species, namely discotylenchus attenuatus and tylenchus bhitaii, are new records for iranian nematode fauna, the male of t. b...

A total of 211 soil samples were collected in different crop fields from 10 districts. Out samples, 137 diagnosed for plant parasitic nematodes. The the cruciferous and solanaceous crops. All together twelve nematodes identified. identified genera are Meloidogyne, Helicotylenchus, Pratylenchus, Tylenchus, Tylenchorhynchus, Hoplolaimus, Belonolaimus, Criconemoides, Aphelenchoides, Hirschmanniell...

Pinus edulis and Juniperus monosperma seedlings were inoculated separately with each of seven nematode species, and grown for 9 months at 20 C soil temperature. Hoplolaimus galeatus, Rotylenchus pumilis, Tylenchus exiguus, and Xiphinema americanum parasitized P. edulis seedlings, but did not significantly reduce seedling growth. Pinus edulis was not a host for Tylenchorhynchus cylindricus, Aphe...

during a survey, five known species of plant-parasitic nematodes of the families tylenchidae and dolichodoridae (tylenchomorpha: tylenchoidea) were collected and identified from several locations in golestan, guilan, kurdistan, and fars provinces. paratrophurus kenanae, tylenchus elegans and t. ritae, as new records for iranian nematode fauna, with the two previously reported species filenchus ...

in order to identify the plant parasitic nematodes associated with polianthes tuberosa in dezful regions, iran, 300 soil and root samples were collected from different parts of the region, during 2012-2014. the samples were washed and the nematodes were extracted by centrifugal flotation technique. the nematodes were fixed and transferred to glycerin, and then the permanent slides of the nemato...

Surveys were conducted in Alexandria, El-Behera, and Matrouh Governorates in northwestern Egypt during the 1994-1998 cropping seasons to study the occurrence, population density, host associations, and distribution of phytoparasitic nematodes associated with 35 major crops, grasses, and weeds. A total of 220 soil and root samples containing mixed populations of 26 genera and 38 species of phyto...
