Abstract

The original sources of nemic parasites are generally unknown. It is, therefore, of considerable interest to find the sugar beet nematode {Heterodera scliachtii Schmidt, 1871), Anguillulina aberrans n. sp., and Neotylenchus lotus n. sp. under conditions that apparently leave no doubt as to their native origin. On May 25, 1927, H. schachtii and A, aberrans were found infesting the roots of shadscale, Airiflex confertifolia (Torr, and Frem.) S. Wats., collected in the desert foothills west of Utah Lake, Utah. Collections made in 1933 extended the desert range of these two nemas into Cedar Valley, several nailes west of the first collection, and to the hills west of Richfield, about 95 . miles south. N. laius also was found in the material collected west of Richfield and in a single collection made west of Utah Lake.
