The time and mode of entry, and development of Ditylenchus destructor in peanut were studied in field and greenhouse experiments. Few nematodes were present in the cortex of the roots. At 90-120 days after planting, D. destructor was observed in the exocarp at the base of the pod near the point of connection with the peg. The peg was invaded from this primary infection site. The endocarp of the hull was usually penetrated through openings at the base of the mesocarp and sometimes at the pod… Expand
Population Dynamics of Ditylenchus destructor on Peanut.
TLDR
The population development of Ditylenchus destructor in the roots, pegs, hulls, and seeds of eight peanut genotypes was studied in the greenhouse and differences in host suitability were observed. Expand
Population Dynamics of Ditylenchus destructor on Peanut 1
T h e population development of Ditylenchus destructor in the roots, pegs, hulls, and seeds of eight peanut (Arachis hypogaea) genotypes was studied in the greenhouse. Al though all genotypes testedExpand
Histological Studies of Ditylenchus africanus Within Peanut Pods.
TLDR
In late-harvested pods, increased numbers of eggs and anhydrobiotes were found in the hull tissues, and eggs in the seed testa, suggesting the onset of winter survival mechanisms of the nematode. Expand
In Vitro Embryo Explant Cultures of Peanut to Evaluate Resistance to Ditylenchus destructor.
TLDR
Resistance or susceptibility to D. destructor was observed in seeds of several genotypes but was not matched by differences in host suitability in roots, indicating that the factor for resistance or susceptibility is synthesized in the seeds of peanut but is not translocated to the roots. Expand
Effect of Host Plant Age on Population Development and Pathogenicity of Ditylenchus destructor on Peanut.
TLDR
It is suggested that as few as 500 nematodes per plant at 12 weeks after planting can build up to injurious levels before harvest and a nematicide should be active for longer than 12 weeksAfter planting to sufficiently suppress the population. Expand
Reproductive and Damage Potential of Ditylenchus destructor on Six Peanut Cultivars.
TLDR
Commercial peanut cultivars were evaluated for host suitability and sensitivity to Ditylenchus destructor and Sellie was the most tolerant and highest yielding cultivar. Expand
Reproductive and Damage Potential of Ditylenchus destructor on Peanut.
The reproductive and damage potential of Ditylenchus destructor on peanut, Arachis hypogaea cv. Sellie, was determined in greenhouse tests. Final nematode population densities (Pf) in roots, hulls,Expand
Differential responses of resistant and susceptible groundnut genotypes at cellular level to Ditylenchus africanus
TLDR
The mechanism of resistance involved may be the inhibition of proper development, migration and reproduction of this nematode, thus preventing it building up to damaging population levels, according to results of this study. Expand
Influence of Temperature on Development and Reproduction of Ditylenchus weischeri and D. dipsaci on Yellow Pea.
TLDR
Development of D. weischeri is temperature dependent and reproduction is unlikely on yellow pea in the Canadian Prairies, where mean daily air temperatures of 27°C are rare and not sustained. Expand
Plant Parasitic Nematodes Intercepted from Seeds, Soil Clods and Packing Material Under Import Quarantine
TLDR
Exotic consignments of seeds, soil as contaminant of seeds and packing material were examined for presence of nematodes, and the importance of plant quarantine was emphasized. Expand
