Comparison of Populations of Pratylenchus brachyurus Based on Isozyme Phenotypes.
Enzymes from females of five Pratylenchus brachyurus populations and one P. scribneri population were analyzed by isoelectric focusing electrophoresis. Of the 18 enzyme systems investigated, only malate dehydrogenase (MDH), phosphoglucomutase (PGM), and phosphoglucose isomerase (PGI) were detected from all five P. brachyurus populations and P. scribneri. Faint bands were detected for isocitrate...
متن کاملMethyl Bromide Fumigation of Pratylenchus brachyurus in Peanut Shells.
Five dosages of methyl bromide were used to fumigate peanut (Arachis hypogaea L.) shells and whole pods of peanuts in 1-liter flasks for 24 hr at 25 C. Methyl bromide dosages as low as 24.5 mg/liter killed all Pratylenchus brachyurus (Godfrey) Filip. &Sch. Stech. in peanut shells. Dosages of 44.6 and 50.9 mg/liter killed all but one or two nematodes in shells of whole pods. A 15% reduction in s...
متن کاملHost Specificity of Four Populations of Pratylenchus brachyurus.
Four populations of the lesion nematode Pratylenchus brachyurus were tested in a greenhouse on seven selected plant species to determine host suitability and usefulness in identifying physiological races of the nematode. The differential plants were 'Florida 77' alfalfa, 'Harvester' snap bean, 'Rough Lemon' citrus, 'Pioneer 304C' corn, 'Florunner' peanut, 'Braxton' soybean, and 'Rutgers' tomato...
متن کاملA key and diagnostic compendium to the species of the genus pratylenchus filipjev, 1936 (lesion nematodes).
An identification key to 63 species of Pratylenchus is given. A compendium of the most diagnostic characters to be used directly in identification of species is included as a practical alternative and supplement to the key. P. tenuis, P. similis, P. impar, P. ranjani, and P. neocapitatus are recognized as valid species on the basis of study of type specimens. P. hyderabadensis Singh &Gill, 1986...
متن کاملPratylenchus, paratylenchus, helicotylenchus, and other nematodes on soybean in missouri.
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...
