“…and Meloidogyne spp. Groups of plant parasitic nematodes have been characterized (Caswell-Chen et al, 1992;Cenis, 1993;Erickson et al, 1993;Roosien et al, 1993;Chacon et al, 1994;Romero et al, 1996;Thiery et al, 1996;Blok et al al., 1997a, b;Williamson et al, 1997;Yu et al, 1998;Fullaondo et al, 1999;Kaplan et al, 1999;Lecouls et al, 1999;Orui, 1999;Boiteux et al, 2000;Silva et al, 2000;Zijlstra et al, 2000;Ambrogioni & Irdani, 2001;Randig et al, 2001;Xu et al, 2001;Meher et al, 2003;Adam et al, 2007;Karajah et al, 2010). RAPD was also used in the species identification of entomopathogenic nematodes and genetic variations among Steinernema carpocapsae, S. feltiae, S. glaseri, Heterorhabditis bacteriophora and H. megidis isolates were determined (Welsh & McClelland, 1990;Williams et al, 1990).…”
