Two years of data collected from the Florida Nematode Assay Laboratory
of the Florida Cooperative Extension Service and 4 years of data from
the Florida Department of Agriculture and Consumer Services, Division
of Plant Industry, were compiled to find out the distribution of Past
euria spp. on nematodes in Florida soils. Information recorded came fr
om 335 samples and included nematode genera with Pasteuria endospores
attached, host plants associated with the samples,and the origins of t
he samples. Pasteuria spp. were detected on 14 different plant-parasit
ic nematode genera in 41 Florida counties and associated with over 39
different plant species and in seven fallow fields. Pasteuria-infected
nematodes were associated with a wide range of plant hosts, although
frequency of associations with these hosts reflected the sample bias o
f the laboratories involved. Meloidogyne and Hoplolaimus spp. were the
two nematode genera most frequently associated with Pasteuria. Pasteu
ria spp. were observed attached to members of these two genera in 176
and 59 soil samples, respectively.
