Morphometric identification of the juvenile stages of Xiphinema index Thorne et Allen

Abstract

Prota et al. (1977) studied the life cycle of Xiphinema index Thorne et Allen in glasshouse to establish the time required for the completion of each stage from egg-laying to adult. Measurements were made of the body length and of the two odontostyles for each of the juvenile stages and these data are presented here as a basis for the morphometric identification of each stage (Dalmasso, 1970).
