In September 2012, root samples of calla were received in
the Laboratory of Nematology, at Instituto Agronômico do
Paraná, IAPAR, derived from a garden on Londrina, Paraná
state, Brazil (23o18′36″S, 51o09′46″W). Roots were free of
galls, showing only thickened portions not typical of
Meloidogyne spp. attack (Fig. 1a). An examination of small
sections of gently washed roots with a stereomicroscope in the
magnificent of 40× showed, after tissue dissection, many
globose females (Fig. 1b). Above-ground symptoms of
wilting or yellowing were absent in the samples.
