A Comparison of Three Inoculating Methods for Egg Parasitism of Meloidogyne incognita by Different Isolates of Paecilomyces lilacinus

  • Received Date: 2003-09-22
  • This study was conducted to assess the parasitism of 13 isolates Paecilomyces lilacinus originating from difference areas on eggs of Meloidogyne incognita.The assay included three treatments:individual eggs treated by spore suspension,individual eggs treated by hypha of fungus,and egg masses treated by spore suspension.Parasitic rate of the same one of all isolates differed in 3 treatments, in which parasitic rate treated by spore suspension was much higher than that in the other two treatments. The results indicated that egg parasitic rate differed significantly among 13 isolates. In the three treatments, parasitic rate of isolate 618 on Meloidogyne incognita eggs was the highest. Parasitic rates of 13 isolates had not relation to the geographical resources of isolates.

Abstract: This study was conducted to assess the parasitism of 13 isolates Paecilomyces lilacinus originating from difference areas on eggs of Meloidogyne incognita.The assay included three treatments:individual eggs treated by spore suspension,individual eggs treated by hypha of fungus,and egg masses treated by spore suspension.Parasitic rate of the same one of all isolates differed in 3 treatments, in which parasitic rate treated by spore suspension was much higher than that in the other two treatments. The results indicated that egg parasitic rate differed significantly among 13 isolates. In the three treatments, parasitic rate of isolate 618 on Meloidogyne incognita eggs was the highest. Parasitic rates of 13 isolates had not relation to the geographical resources of isolates.
