| Abstract/Contents: | "A new species of Pasteuria (S-1) was discovered that parasitizes the sting nematode, Belonolaimus longicaduatus. Host range studies with several species of soil inhabiting nematodes have demonstrated that this obligate endoparasitic bacterium only attaches to members of the genus of Belonolaimus. Ultrastructural and morphometric studies of mature and developing endospores with transmission and scanning electron microscopy (TEM and SEM) have shown that this Pasteuria is unique relative to the other described species of Pasteuria but that different geographical isolates are morphologically and morphometrically constant. A two-year survey was conducted with 6 different sites of hybrid bermudagrass (Fairways) at the Ft. Lauderdale Research and Education Center where Pasteuria (S-1) occurs naturally at different levels to monitor its suppressive effects at three different soil depths on sting nematodes. Density dependent regulation of sting nematodes appears to be occurring in areas with Pasteuria (S-1). Survey locations that started with low levels of spore encumbrance showed a building tend in encumbrance levels and a corresponding decline in the numbers of sting nematodes. Locations with high spore encumbrance levels cycled and appear to suppress sting nematode population resurgences, suggesting that Pasteuria (S-1) might help produce suppressive soil for the sting nematode in the turfgrass ecosystem. An eighteen month study was completed that compared the effects of inoculation with 900 mls of Pasteuria (S-1) spore-infested soil (ca. 5,000 endospores/ml) versus 900 mls of autoclaved soil in 1 m2 'Tifdwarf' bermudagrass (Greens) plots. This study showed that a relatively small amount of Pasteuria-infested soil can be introduced into a USGA green with high numbers of sting nematodes and bring about density dependent suppression within about 12 months." |
