Description of the Blueberry Root-knot Nematode, Meloidogyne carolinensis n. sp.
Abstract
Meloidogyne carolinensis n. sp. is described from cultivated highbush blueberry (cultivars derived from hybrids of Vaccinium corymbosum L. and V. lamarckii Camp) in North Carolina. The perineal pattern of the female has a large cuticular ridge that surrounds the perivulval area, and the excretory pore is near the level of the base of the stylet. The stylet is 15.9 ,am long and the knobs gradually merge with the shaft. The head shape and stylet morphology of the male are quite variable. The typical head and four variants, as well as the typical stylet and two variants, are described. The labial disc, medial lips, and lateral lips of second-stage juveniles are fused and in the same contour. The head region is not annulated. Mean juvenile length is 463.7 [mu]m, stylet length is 11.9 [mu]m, and tail length is 42.5 [mu]m. Key words: taxonomy, morphology, new Meloidogyne species, host range, scanning electron microscopy.Downloads
