Ditylenchus destructor in Hulls and Seeds of Peanut.
The potato rot nematode, Ditylenchus destructor Thorne, is reported for the first time in hulls and seeds of peanut. The populations found differed from D. dipsaei and D. myceliophagus in habitat,… Expand

Morphological and morphometric characters as well as DNA sequencing of the D2–D3 expansion segments of 28S rRNA confirmed the identity of the nematodes extracted from apple roots and confirmed the host status of apple for P. hippeastri in South Africa. Expand
Effect of watering regimen on injury to corn and grain sorghum by pratylenchus species.
It is concluded that water stress is not the only environmental factor that influences the pathogenicity of these two species on corn and sorghum. Expand

Syconia ("figs") from Ficus thonningii and adults of its pollinator wasp Elisabethiella stuckenbergi were dissected to elucidate their association with a new species of Schistonchus (Aphelenchoididae) and Nematode populations extracted from female wasps or fig floret tissues did not differ in their morphology.

Partial tetrasomy of 9P: a rare chromosomal abnormality in polycythaemia vera.
The interaction of stem strength with plant density and nitrogen application in wheat progeny from parents with varying stem strength
The aim of this study was to study the effect of different N treatments and plant densities on stem strength of selected cultivars and their hybrids and found that the thicker the stem cortex and the thickness of the pith, the stronger the stem of the plant. Expand
Morphological and molecular characterization of Hoplolaimus pararobustus (Schuurmans Stekhoven and Teunissen, 1938) Sher 1963 with its first report on Zea mays roots in Namibia
This Namibian population of H. pararobustus is the first Hoplolaimus species from Africa to be molecularly characterized and is described and illustrated based on its morphological, morphometric, and molecular characteristics. Expand
