Nematode reproduction on endophyte-infected and endophyte-free tall fescue.
Infection of tall fescue with the endophytic fungus Acremonium coenophialum has been shown to reduce nematode population in field soils, and reproduction of three plant-parasitic nematodes on endophyte-infested (E+) and endophytes-free (E−) tallfescue in greenhouse tests was evaluated.
Relative susceptibility of selected cultivars, of potato to Pratylenchus penetrans.
Pratylenchus penetrans suppressed the tuber yields of potato cultivars 'Katahdin', 'Kennebec', and 'Superior', but did not affect yields of 'Russet Burbank', and symptoms of nematode invasion were confined to losses of tuber yield and root weight.
Nematode population and community dynamics in soybean-wheat cropping and tillage regimes.
It was shown that plant-parasitic nematode communities produced an aggregation of conventionally tilled, single-cropped soybean plots when compared to all double-cropping treatments, and ordination of overall nematodes yielded similar results.
Pratylenchus hippeastri n. sp. (Nematoda: Pratylenchidae) from amaryllis in Florida with notes on P. scribneri and P. hexincisus.
A new root-lesion nematode Pratylenchus hippeastri n. sp. is described from amaryllis (Hippeastrum spp.) in Florida. The new species is characterised by a combination of the following morphological…
Soil Invertebrate Species Diversity and Abundance in Endophyte-Infected Tall Fescue Pastures
The purpose of this review is to analyze recent progress made in the understanding of the role of the endophyte (Neotyphodium coenophialum)-tall fescue (Festuca arundinacea) symbiosis in regulation of invertebrate communities, and to suggest fruitful lines of research for the future.
COI haplotype groups in Mesocriconema (Nematoda: Criconematidae) and their morphospecies associations.
It is indicated that some of the species considered cosmopolitan in their distribution are actually multispecies polyphyletic groupings and an accurate assessment of Mesocriconema species distributions will benefit from molecular determination of haplotype relationships.
Fungal parasitism of soybean cyst nematode, Heterodera glycines (Nemata: Heteroderidae), in differing cropping-tillage regimes
Description of the Kona Coffee Root-knot Nematode, Meloidogyne konaensis n. sp.
The morphology of the stylet of the male is the most useful diagnostic character, with 6-12 large projections protruding from the shaft, and one medial lip may be divided into distinct lip pairs.
Survey of Pogonognathellus Börner (Collembola: Tomoceridae) in the Southern Appalachians Based on Morphological and Molecular Data
P Pogonognathellus Börner is the most common genus of tomocerid Collembola in the southern Appalachian region of the United States and two new species are described.
Identification, distribution, and plant associations of plant-parasitic nematodes in Tennessee.
- E. C. Bernard
A survey of the plant-parasitic nematode fauna of Tennessee was conducted to determine number and distribution of species, and associations of plant-use types with nematodes species, to identify the most common species.
