The influence of fibre in the diet on growth rates and the digestibility of nutrients in the greater cane rat (Thryonomys swinderianus).
Population Dynamics of Ditylenchus destructor on Peanut.
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.

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.
Effect of Host Plant Age on Population Development and Pathogenicity of Ditylenchus destructor on Peanut.
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.
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,…
Survival of Ditylenchus destructor in soil, hulls and seeds of groundnut.
The results show that the freshness of the tissues played an important role in the efficiency of the soaking method : stored hulls and seeds must be soaked longer than 24 h to make a reliable estimate of the number of nematodes present.
An evaluation of crop plants as hosts for Ditylenchus destructor isolated from peanut.
In all host lines, including 'Sellie' peanut, the number of D. destructor recovered per root system was lower than thenumber of nematodes used for inoculation.
Minimizing damage by Ditylenchus destructor to Peanut Seed with Early Harvest.
Greenhouse and microplot experiments were conducted to evaluate the damage potential of Ditylenchus destructor on four South African commercial peanut cultivars as influenced by harvest date, finding that although seed weight increases with time, a net loss occurs if harvest is delayed.
Reproductive and Damage Potential of Ditylenchus destructor on Six Peanut Cultivars.
Commercial peanut cultivars were evaluated for host suitability and sensitivity to Ditylenchus destructor and Sellie was the most tolerant and highest yielding cultivar.
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 tested…
