GOMEZ, Lucila; GANDARILLA, Hortensia  and  RODRIGUEZ, Mayra G. Pasteuria penetrans AS A BIOLOGICAL CONTROL AGENT OF Meloidogyne spp. Rev. Protección Veg. [online]. 2010, vol.25, n.3, pp.137-149. ISSN 1010-2752.

The objective of this paper is to summarize the current knowledge of the biology, ecology and potentialities of P. penetrans and others Pasteuria members as biological control agents Pasteuria penetrans is a mycelial, endospore-forming, bacterial parasite that has shown great potential as a biological control agent of root-knot nematodes. Considerable progress has been made during the last years in understanding its biology and importance as an agent capable of effectively suppressing root-knot nematodes in field soil. Pasteuria spp. are distributed worldwide and have been reported from 80 countries, parasitizing 323 nematode species belonging to 116 genera of free-living, predatory, plant-parasitic, and entomopathogenic nematodes. Temperature and physico- chemical conditions, as well as biological factors in the soil play an important role in their biology and pathogenesis. Artificial cultivation of P. penetrans has met with limited success; large-scale production of endospores depends on in vivo cultivation. The potentialities of P. penetrans in management of Meloidogyne spp. populations are also examined in this review.

Keywords : Pasteuria penetrans; Meloidogyne spp; biological control; ecology; adhesion mechanisms.
