| Abstract/Contents: | "Rutgers University scientists investigate the effects of soil moisture and soil type on the infectivity and persistence of entomopathogenic nematodes (Heterorhabditidae and Steinernematidae) for short- and long-term suppression of white grubs. Their findings include: The entomopathogenic nematode Steinernema scarabaei showed high virulence across a wide range of substrate types in laboratory and greenhouse studies. While S. scarabaei infectivity tended to decline from the coarser sandy soils to the finer clay soils, high mortality was observed in greenhouse pot experiments even in the finest soils. Only in highly acidic sand (pH 3.9) and highly organic potting mix did S. scarabaei infectivity decline significantly, however, still caused significant mortality. Heterorhabditis bacteriophora showed similar infectivity from the coarser to the finer soils, was also negatively affected in acidic sand, but was most infective in a highly organic potting mix. Both S. scarabaei and H. bacteriophora were most infective at moderate soil moisture levels and less in saturated soil and drier soil. However, the infectivity range of S. scarabaei extended further into the dry range with significant activity even in dry soil (-3,000 kPa). S. scarabaei also showed high persistence levels in all substrate types and soil moisture levels, whereas H. bacteriophora generally was short with good persistence only in the drier soils. S. scarabaei has excellent potential for short-term and long-term suppression of white grub populations." |
