Suppression of Meloidogyne incognita and M. javanica by Pasteuria penetrans in Field Soil.
The role of Pasteuria penetrans in suppressing numbers of root-knot nematodes was investigated in a 7-year monocuhure of tobacco in a field naturally infested with a mixed population of Meloidogyne incognita race 1 and M. javanica. The suppressiveness of the soil was tested using four treatments: autoclaving (AC), microwaving (MW), air drying (DR), and untreated. The treated soil bioassays cons...
متن کاملAffect of Different Ages of Second Stage Juveniles of Meloidogyne Chitwoodi on the Attachment of Pasteuria Penetrans to the Cuticle of Nematode
Pasteuria penetrans is a bacterial parasite of some plant parasite of nematodes whichcan attach to the cuticle of nematode. Differences in attachment of P. penetrans spores to the second stag juvenile (J2) cuticle may provide evidence for nematode cuticle diversity even between different ages of J2s. For investigating this purpose, we studied the effect of different ages of th...

متن کاملPasteuria penetrans for Control of Meloidogyne incognita on Tomato and Cucumber, and M. arenaria on Snapdragon.
Meloidogyne incognita and Meloidogyne arenaria are important parasitic nematodes of vegetable and ornamental crops. Microplot and greenhouse experiments were conducted to test commercial formulations of the biocontrol agent Pasteuria penetrans for control of M. incognita on tomato and cucumber and M. arenaria on snapdragon. Three methods of application for P. penetrans were assessed including s...
متن کاملMeloidogyne incognita Fatty Acid- and Retinol- Binding Protein (Mi-FAR-1) Affects Nematode Infection of Plant Roots and the Attachment of Pasteuria penetrans Endospores
Root-knot nematode (RKN) Meloidogyne incognita is an economically important pest of crops. Pasteuria penetrans, is a nematode hyperparasitic bacterium capable of suppressing the reproduction of RKN and thereby useful for its management. Secreted fatty acid and retinol-binding proteins are unique in nematodes and are engaged in nutrient acquisition, development and reproduction; they are also a ...
