Ectoparasitic feeding behaviour of the root lesion nematode, Pratylenchus penetrans, on root hairs of different host plants
نویسنده
چکیده
The feeding behaviour of Pratylenchus penetrans on root hairs was observed using video-enhanced contrast microscopy. The behayiouk could be separated into phases of probing, ce11 penetration by the stylet, salivation and food ingestion for brief and extended ,periods. &ter cell penetration, a small “ salivation zone ” was formed around the stylet tip. No feeding tubes were observed. The root hairs responses to nematode feeding included increased rate of cytoplasmic streaming and gradual hypertrophy of the root hair nucleus. The observations are discussed in relation to work on the ectoparasitic feeding behaviour of nematodes.

Interaction of Pratylenchus penetrans and Rhizoctonia fragariae in Strawberry Black Root Rot.
A split-root technique was used to examine the interaction between Pratylenchus penetrans and the cortical root-rotting pathogen Rhizoctonia fragariae in strawberry black root rot. Plants inoculated with both pathogens on the same half of a split-root crown had greater levels of root rot than plants inoculated separately or with either pathogen alone. Isolation of R. fragariae from field-grown ...

Root-lesion disease, which is caused by Pratylenchus loosi , is one of the most important diseases currently impacting Iran tea plantations. This disease causes great economic crop impacts. Northern provinces, which supply much of Iran’s tea production, have been especially hard impact by root-lesion disease.The purpose of this study was to biological control the nematodes as one of the main se...

The joint action of a plant parasitic nematode, Pratylenchus penetrans (root-lesion nematode), and an insect defoliator, Leptinotarsa decemlineata (Colorado potato beetle), on growth, development, and yield of Solanum tuberosum cv. Superior was studied in the field. Three population densities of P. penetrans were superimposed on each of three population levels of L. decemlineata. The major impa...

The fungus Gnomonia comari, causal agent of strawberry leaf blotch, was inoculated at the crown of young axenized strawberry plants growing in sterilized sand. Only the roots were colonized, and the infection was symptomless. When the fungus colonized the roots in the presence of the root lesion nematode Pratylenchus penetrans, the plants were extremely stunted and their root system was necroti...

The interaction of lesion nematodes, black root rot disease caused by Rhizoctonia fragariae, and root damage caused by feeding of the scarab larva, Maladera castanea, was determined in greenhouse studies. Averaged over all experiments after 12 weeks, root weight was reduced 13% by R. fragariae and 20% by M. castanea. The percentage of the root system affected by root rot was increased by inocul...
