Abstract

Morphometric variation of Rotylenchulus parvus and Rotylenchulus reniformis populations in the southern United States.

Abstract

The morphometrics of immature females of Rotylenchulus parvus and R. reniformis from various geographic regions of the southern United States were within the range of variation reported for other R. parvus and R. reniformis populations from other countries. Populations of these two Rotylenchulus species from the USA could be easily separated by the lengths of the immature female body, stylet and tail , which were greater for R. reniformis than for R. parvus. Using information from the literature, and based on 52 populations from different geographic areas, a compendium of morphometric data and a key were prepared for the valid species of Rotylenchulus.
