Feeds on leaf surfaces and in the crowns of the bromeliad, Tillandsia flabellata. The nematodes do not penetrate the leaves.
Large numbers of nematodes may be found in crowns just below the water line.
The bromeliad, Tillandsia flabellata (Lehman, 1986)..
Ecophysiological Parameters:
Clusters of nematodes and eggs remain on dry , dead leaves, appearing as a woolly mass.
Healthy bromeliad plants show light brown lesions on the upper surfaces of leaves about 6 weeks after inoculation with the nematode In severe infections flowering is inhibited and leaves die (Lehman, 1986)..
Inspection of plants imported from Central America.
Roguing of dead leaves to remove nematode incoculum.
Treatment with oxamyl has been effective (Lehman, 1986).
