    Juveniles emerge from galls at the start of the fall rainy seson and move between the cotyledons of the emerging host tissues.. They penetrate the first true leaves of the capeweed seedlings and galls are observed on the surface of the leaves after about 10 days.  The galls contain around 5 adults, both males and females.  The firs eggs appear after about 5 weeks and the first juveniles 2 months after penetration of the infective juveniles.  Young adults are present about 3 weeks later.  Several generations are completed in the gall.  The nematode survives the dry summeras third-stage juveniles in the dry galls. (Chit and Fisher, 1975).
