The Life Stages of Helicotylenchus Multicinctus (Cobb) in Banana Roots

The life stages of Helicotylenchus multicinctus from banana roots are described and measurements, related to the identification of these stages, presented. Eggs occurred in groups within cells of the outer cortex. Second stage larvae possessed a ventrally digitate tail process similar to that found in H. erythrinae. The tail process disappeared during the course of the second molt. Data are presented on morphological differences between anterior and posterior gonads.
