Prevalence of pest nematodes associated with soybean (<i>Glycine max</i>) in Wisconsin from 1998 to 2021 Open
The prevalence of Heterodera glycines and other cyst and vermiform genera was determined from 8,009 soil samples over two decades. Prevalence of cyst nematodes for farms increased from 16% in 1998 to 1999, reaching a peak of 40%, with mark…

<i>Pratylenchus smoliki</i>, a new nematode species (Pratylenchidae: Tylenchomorpha) from the Great Plains region of North America Open
Pratylenchus smoliki is a new species of root-lesion nematode described from corn-soybean production fields in the Central Great Plains of North America. It is characterized by populations with relatively abundant males, two lip annuli, fe…

Intraspecific variation in phenotypic and phylogenetic features among <i>Pratylenchus penetrans</i> isolates from Wisconsin, USA Open
Pratylenchus penetrans is a common and important agricultural pest in Wisconsin, a USA state with a diverse agriculture. We compared populations from around the state to each other and to data published for populations around the world to …

Difference in lesion formation by male and female <i>Pratylenchus penetrans</i> Open
Pratylenchus penetrans induce necrotic lesions, the hallmark symptom for the genus, soon after infection. The objective of our study was to characterize and quantify gender differences in lesion development. Independent experiments were co…

Prevalence of the root lesion nematode virus (RLNV1) in populations of <i>Pratylenchus penetrans</i> from North America Open
Root lesion nematode virus 1 (RLNV1) was discovered in the migratory endoparasitic nematode species Pratylenchus penetrans . It was found in a P. penetrans population collected from soil samples in Beltsville, Maryland, USA. In this study,…

Incidence of <i>Oscheius onirici</i> (Nematoda: Rhabditidae), a potentially entomopathogenic nematode from the marshlands of Wisconsin, USA Open
In a search for an entomopathogenic nematode to control cranberry insect pests, three Oscheius populations (Rhabditidae) were recovered through the Galleria- bait method from one sample taken in a wild cranberry marsh in Jackson County, Wi…

Development of a Damage Function Model for <i>Pratylenchus penetrans</i> on Corn Open
The lesion nematode Pratylenchus penetrans is a common pest of corn in the north-central United States. There are relatively few studies documenting the impact of Pratylenchus spp. on grain yield even though they are recognized as pests of…
