Nematode reproduction on endophyte-infected and endophyte-free tall fescue.
Infection of tall fescue (Festuca arundinacea) with the endophytic fungus Acremonium coenophialum has been shown to reduce nematode population in field soils. We evaluated reproduction of three… Expand
Nematode population and community dynamics in soybean-wheat cropping and tillage regimes.
The nematode community structures of various soybean-wheat regimes and of a single-cropped, conventionally tilled soybean regime were studied at two sites in Tennessee. Each of the 100 nematode… Expand
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'. In comparison with noninfested controls,… Expand
Fungal parasitism of soybean cyst nematode, Heterodera glycines (Nemata: Heteroderidae), in differing cropping-tillage regimes
Abstract A 2 year field study was designed to determine if soybean-wheat double-cropping and reduced or no tillage altered the soil mycoflora antagonistic to the soybean cyst nematode, Heterodera… Expand
COI haplotype groups in Mesocriconema (Nematoda: Criconematidae) and their morphospecies associations.
Without applying an a priori bias for species boundaries, specimen identities in the plant-parasitic nematode genus Mesocriconema were evaluated by examining mitochondrial COI nucleotide sequences,… Expand
Description of the Kona Coffee Root-knot Nematode, Meloidogyne konaensis n. sp.
Meloidogyne konaensis n. sp. is described from coffee from Kona on the island of Hawaii. The perineal pattern of the female is variable in morphology, the medial lips of the female are divided into… Expand
Survey of Pogonognathellus Börner (Collembola: Tomoceridae) in the Southern Appalachians Based on Morphological and Molecular Data
ABSTRACT Pogonognathellus Börner is the most common genus of tomocerid Collembola in the southern Appalachian region of the United States. Scale pattern, cuticle color, and molecular data were used… Expand
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… Expand
Soil Invertebrate Species Diversity and Abundance in Endophyte-Infected Tall Fescue Pastures
The reduced ability of many herbivorous insects and nematodes to subsist on grasses infected by endophytic fungi is well-documented (Clay, 1989;1991). These effects upon insects are mostly due to the… Expand
Identification, distribution, and plant associations of plant-parasitic nematodes in Tennessee.
- E. 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 nematode species. Seventy-five… Expand
