Background: Plant-parasitic nematodes are important pests of horticultural crops causing damage and significant reduction in the crop yield of pineapple. A survey was conducted to determine the types, frequency and population distribution of plant-parasitic nematodes associated with pineapple in some pineapple-producing states in Nigeria. A total of 30 farms were sampled from Delta, Imo, and Cr...

In Arkansas wheat is commonly grown either in rotation or double cropped with soybean. Surveys from 1986 to 1988 identified 18 phytoparasitic nematode species in Arkansas wheat fields. The frequency of occurrence, as a percentage of the total number of samples (199), for the following nematodes was Heterodera glycines 43%, Quinisulcius acutus 40%, Pratylenchus scribneri 37%, Helicotylenchus pse...

Morphological and morphometric analyses were conducted on the genus Paratylenchus, based on documented data in the literature and characters of Iranian populations of twelve species, including P. arculatus, P. colinus, P. conicephalus, P. coronatus, P. neoamblycephalus, P. neoprojectus, P. obtusicaudatus, P. paraperaticus, P. similis, P. straeleni, P. variabilis and P. veruculatus. Moreover, ma...

three species of paratylenchus were collected and identified from vineyards and apple orchards in kermanshah province, western iran. descriptions, morphometric data, line drawings and microscopic photographs are provided for these three species. paratylenchus audriellus and paratylenchus straeleni are the two very closely related species, with a stylet longer than 40 µm, four lateral lines and ...

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...

Eighteen species in eight genera of plant-parasitic nematodes were identified from soil samples collected from soybean fields throughout Missouri. The genera represented were Helicotylenchus, Heterodera, Hoplolaimus, Meloidogyne, Paratylenchus, Pratylenchus, Tylenchorhynchus, and Xiphinema. Three fields, each with high densities of Helicotylenchus pseudorobustus, Pratylenchus hexincisus, or Par...
