Evaluation of Pasteuria penetrans as a biocontrol agent against populations of root-knot nematode populations from Crete.

Abstract

The attachment of spores from different populations of Pasteuria penetrans was assessed using a field population of root-knot nematodes from Crete consisting of 75% Meloidogyne incognita and 25% M. javanica. Juveniles were more heavily encumbered with spores of an isolate of P. penetrans from South Africa and from a population consisting of a mixture of P. penetrans isolates than by spores from two other populations. When single egg mass lines of the component species of the Cretan root-knot nematode population were tested, it was found that M. javanica was the more susceptible species. A greater proportion of the nematodes encumbered with 5-8 spores eventually became infected than did juveniles that were encumbered by fewer spores.
