Resumen

GALLEGOS-MORALES, Gabriel et al. Beneficent Microorganisms Associated to Meloidogyne incognita (Kofoid & White) Chitwood in Guava (Psidium guajava L.) of Calvillo, Aguascalientes, México. Rev. mex. fitopatol [online]. 2009, vol.27, n.2, pp. 106-112. ISSN 0185-3309.

The root-knot nematode species Meloidogyne incognita was identified as the one species that parasites guava orchards in the Calvillo region (Aguascalientes, Mexico). Beneficent fungi and bacteria were isolated as well, associated to soil and roots collected from the Cerro Blanco, Mesa Grande, La Labor and Malpaso locations. Twenty different Meloidogyne sp., samples were identified taking adult female perinea pattern characteristics into account, as well as the male anterior region observation. The Meloidogyne incognita species was identified in all the samples. The isolated beneficent microorganisms and associated to guava rhizosphere with a potential use in biological control, belong to the Bacillus cereus, B. subtilis B. megaterium and Paecilomyces farinosus species. Furthermore, the Rhabditis and Mononchus soil nematodes were identified in the samples.
