| Abstract: | "Rhizosphere microorganisms play an important role in the interactions of many species in the rhizosphere, including soil nematodes. One hundred strains of rhizosphere actinomycetes were screened in vitro for their effects on the chemotactic behavior of the root-knot nematode, Meloidogyne incognita. Volatile compounds produced by the strain Streptomyces plicatus G demonstrated both strong attractant and repellent activities towards M. incognita. The compound dibenzofuran attracted M. incognita nematodes strongly, while compound benzothiazole repelled them. The chemotaxis of M. incognita was also tested under controlled conditions in pot experiments. Cultures of S. plicatus G and volatile dibenzofuran attracted M. incognita while volatile benzothiazole repelled them. The results showed that volatile compounds produced by rhizosphere actinomycetes could influence the chemotaxis of nematodes to a host. This study provides new information about the interrelationship between rhizosphere actinomycetes and nematodes that may be useful in preventing nematode parasitism of agricultural crops" |
